Editor’s Note

On May 23, IEEE ComSocSCV and IEEE Power Electronics members were treated to a superb talk and tour of the Coresite Multi-Tenant Data Center (DC) in Santa Clara, CA.  There are a total of 11 network operators and cloud service providers that have brought fiber into that DC for their customers who share fiber access.   The SMF or MMF from each customer’s co-lo cage is physically routed (under the floor) to a fiber wiring cross-connect/patch panel maintained by Coresite.  The output fibers are then routed to a room where the network/cloud providers maintain their own fiber optic gear (multiplexers/switches, DWDM equipment, etc) which connect to the outside plant fiber optic cable(s) for each provider.

The outside plant fiber fault detection and restoration are done by each fiber provider- either via a mesh network or 1:1 or N:1 hot standby.  Coresite’s responsibility ends when it delivers the fiber to the provider cages.  They do, however, have network engineers that are responsible for maintenance and trouble shooting in the DC when necessary.  Very impressive indeed!

 

5G Telecom Investments, Hype, Huawei & 5G replacement for cable broadband?

Wharton’s Kevin Werbach and Jeffrey Reed from Virginia Tech discuss whether 5G technology will live up to its promise.

Telecom companies and other providers will have to invest billions to make 5G a reality — not only to buy more spectrum, but also to build out the infrastructure. Because it’s yet uncertain how much revenue 5G will bring, for now the most prudent path for telecom firms is to upgrade the capacity of their 4G networks by reclaiming airwaves allocated for 2G and 3G, as well as buying more spectrum, according to a report by McKinsey. (The lower bands can be used for 5G as part of the carrier’s network management plan, even though data capacity won’t be as good.)

But there will come a time when these tactics won’t be enough. Historically, data traffic rises by 20% to 50% a year, and 5G could put the traffic increases at the higher end of that range, the McKinsey report said. That means most telecom companies will have to embark on a “significant new build out” between 2020 and 2025. Also, to handle higher traffic, carriers have to install fiber in their wired networks, where wireless connects to the internet. “It’s rather ironic that the projected performance goals of 5G wireless will depend on the availability of wireline fiber,” an executive at telecom equipment maker Ciena said.

Carriers can’t just label their service 5G, which is a lesson AT&T learned when it was sued by Sprint for putting “5GE” on its service despite not using true 5G. AT&T reportedly settled the lawsuit, explaining that “E” stands for “Evolution.” A Verizon spokesman tweeted that “5GE” stood for “5G Eventually.”

Regarding using millimeter wave spectrum for 5G:

“When you’re transmitting and receiving at very high frequencies, it is very efficient for carrying lots and lots of data,” said Gerald Faulhaber, Wharton professor emeritus of business economics and public policy and former FCC chief economist. “You can carry much, much more data than you ever could using our 4G phones.”

But a key drawback is that these signals travel only short distances. The wavelengths in this band range from 1 mm to 10 mm — the FCC’s December auction is called the millimeter wavelength auction — so these can’t reach very far and are easily degraded. “Very high frequency radio signals travel in direct, straight lines, and they attenuate very quickly,” Faulhaber said. In comparison, very low frequency 30 hertz signals can travel more than 10,000 km, or 6,200 miles. Lower frequencies also can better penetrate solid objects like buildings and walls.

Because millimeter wavelengths are short, they need more antennas to connect. “One of the things that 5G requires is a much denser network,” Werbach said. “You need many more nodes. That is partly how the capacity increases, which means either more towers or more cells in more places. You need equipment that is running on those cell sites, and then you need chips that go into people’s handsets and devices.” At least, the 5G antennas are small and can be installed easily on top of telephone poles and other locations, Faulhaber said.

Because it requires density, 5G mainly is feasible for more populated areas where many antennas can be placed close together. “The nature of the infrastructure is that it works in dense areas; it doesn’t work as well in other areas,” Faulhaber said. “Will there be 5G in [rural areas]? The answer is yes, but it won’t be over these high-frequency antennas. It will be basically where 4G is today, so you won’t get the high-capacity [service].”

Telecom carriers have deployed limited 5G commercial service.

  • In April, AT&T said mobile 5G is live in parts of 19 cities, with more cities to come. In the same month,
  • Verizon said 5G service has launched in parts of Chicago and Minneapolis, where typical early adopters experience download speeds of 450 Mbps and peak speeds of 1 Gbps. That is six and 14 times faster than the median fixed broadband speed of 72 Mbps respectively, according to a December 2018 FCC report. Verizon expects to deploy limited 5G in more than 30 cities this year. Last fall, it launched a limited 5G home internet service in four cities.
  • Sprint is rolling out 5G in nine markets this year.  On May 31st Sprint announced the availability  for its first two 5G devices, LG V50 ThinQTM 5G and HTC 5G Hub. Both devices will initially be available to customers in the first four 5G markets – Atlanta, Dallas, Houston and Kansas City.
  • T-Mobile is calling out its rivals over their 5G hype. “I have the exact same 5G mmWave network equipment and software that AT&T and Verizon do, and there’s no way we would launch this for customers right now,” CTO Neville Ray wrote in a blog. The millimeter wave signal “doesn’t travel far from the cell site and doesn’t penetrate materials at all,” he said. Ray’s blog even embedded a moving image showing that millimeter waves can’t even go through a door. T-Mobile will bring 5G to market, he said, “when the technology is ready for everyday customer use.”

Telecom analyst Craig Moffett of MoffettNathanson echoed similar doubts on CNBC. “There’s zero chance that 5G is ubiquitous technology” by 2021, he said. “The promises around 5G being insanely fast are partly because the standards for 5G were set for insanely wide blocks of spectrum. But you can’t find insanely wide blocks of spectrum anywhere except in these kind of stratospherically high frequencies,” which has its own technical problems. He noted that China, which is surging ahead on 5G, doesn’t use millimeter wave but rather lower band spectrum below 6 GHz, while Europe is using a combination of the two.

Politics also influences U.S. carrier adoption of 5G. The government has security concerns about using 5G telecom equipment from China’s Huawei because of fears over spying. Huawei is the world’s largest maker of telecom equipment, including that needed for 5G. It became a colossus, and “a key reason for that is they produce very inexpensive equipment. It is much cheaper than [that of] their European competition,” Reed said. Huawei doesn’t have any U.S. competition, because infrastructure providers left the business about 20 years ago, he added.

Today, Europe and other parts of the world are customers of Huawei. Britain and Germany specifically are resisting pressure from the U.S. to stop using Huawei. Their carriers have used Huawei in their networks for years, so “for them, it is very difficult to say … ‘rip it all out and go find someone else,’” Werbach said. “They’re just not going to do it.” Added Reed: “Even though a security threat exists with Huawei, companies tend to look the other way to maximize profits, lower costs.” As for security, “that’s way down on their list,” Reed said.

Werbach explained that the U.S. can’t address these security concerns by merely saying it will not use this equipment. It has to be more proactive. “We need to invest in companies in the U.S. and bring trust around the world that, for example, the U.S. is not putting similar kinds of back doors into equipment made by U.S.-based service providers.”
Will 5G Replace Cable?

Even with 5G’s drawbacks, enthusiasm for it remains unabated. One big hope is that 5G could be a viable alternative to the wired broadband service provided by cable and telecom companies. “Could 5G … be the new single pipe into the home?” Faulhaber asked. But before one gets excited about competition bringing lower prices and better service, remember that the same companies currently providing wired broadband to the home are the ones launching 5G. “Guess who are the two dominant wireless operators that have … a big chunk of the spectrum in the service? AT&T and Verizon, who, of course, are also major wired broadband providers,” Werbach noted.

However, Werbach acknowledged that there potentially could be other players in 5G, such as T-Mobile, Sprint and Comcast. Indeed, T-Mobile and Sprint have been trying to convince regulators to let them merge because then they would have the heft to deploy 5G nationally. But The Wall Street Journal reported in April that the deal is unlikely to be approved as structured.

As for Comcast, Faulhaber pointed out that the cable giant already has installed plenty of Wi-Fi receivers, including in customers’ routers that other folks on its network can use to access the internet. “Xfinity Wi-Fi is all over the place and I would suspect we would see something like that with 5G,” he said. But Faulhaber also pointed out that Comcast has time to figure out a response to 5G since it won’t have to worry about competition from this new technology in the near future.

Comcast CFO Michael Cavanaugh put it this way at a recent conference: “The threat of 5G to our broadband business is not significant any time soon. That’s because [cable is] going to be the most economic way to deliver high-quality broadband, period.”

Any cable rival will need “high capacity, high speed and … high reliability,” he said. “Between the different ways, different levels of spectrum and approaches to 5G, it’s really hard to see how there’s a path to any one of those being a broadly addressable solution for residential [broadband] in the U.S.”

Inside Verizon’s 5G lab + Sunday NY Times: Can Holograms Give Surgeons X-Ray Vision?

Verizon showed off new technology at its Cambridge, MA lab last week, seeking to demonstrate that (pre-standard) “5G” networks are as much about reducing latency as they are about providing blazing speeds.  (That’s bizarre because the low latency component of 5G won’t be specified until 3GPP Release 16 and IMT 2020).

The #1 U.S. wireless telco showed out a robot that could potentially rescue people in dangerous situations and explained how 5G will lead to advances in education, medicine and other areas.  “With 5G, the robot and the operator can communicate instantly,” said Yan Gu, an assistant professor of mechanical engineering at the University of Massachusetts, Lowell.

Verizon paid for a “5G” flyer ad insert in Sunday’s NY Times: Verizon 5G Ultra Wideband Brings AR Surgery to Life.  It was quite impressive, but very futuristic in this author’s opinion.  “Verizon 5G Ultra Wideband is a new canvas for innovation.” said CHRISTIAN GUIRNALDA, DIRECTOR OF VERIZON’S 5G LABS.

At Columbia University, staff and students use Verizon’s 5G Labs to experiment with remote physical therapy using virtual reality. The technology allows patients and therapists to use a virtual reality headset and controller to manipulate shared objects within a virtual environment. This level of smooth interactivity and responsiveness is possible with Verizon 5G Ultra Wideband connectivity.

Current Status of “5G” in U.S.:

In the US, Verizon and AT&T, the nation’s two biggest wireless carriers, have switched on mobile 5G networks in only a small handful of locations. Sprint just turned on its network in four cities at the end of May, right about the same time that wireless carrier EE became the UK’s first 5G provider.

Verizon customers looking to experience “5G” right now will have to head to Chicago or Minneapolis, and then find the right street corners — plus buy one of the very few 5G-capable phones out there at the moment. By the end of this year, you won’t have to look quite so hard. Verizon plans to double the coverage area in those two cities, and also drop “5G” into 30 additional cities. (In addition, the company has a “5G” home service in Houston, Indianapolis, Los Angeles and Sacramento, California.)

……………………………………………………………………………………………………………………………………………………………………..

5G use cases and applications -from remote surgery to mixed reality and autonomous cars – are expected to thrive. “They just get better with 5G,” said Christian Guirnalda, director of Verizon’s 5G Labs.

To help drive that point home, Verizon’s demo before a group of journalists showcased a small array of projects experimenting with 5G in health care, manufacturing and public safety, tapping into the company’s Ultra Wideband service. It was a showcase of winners of the company’s 5G Robotics Challenge and other partners working in the Cambridge facility.

The Cambridge lab, set in a colonial-style brick building on a leafy side street nestled next to the Harvard University campus, is one of five that the company’s currently operating. The others are in New York; Washington, DC; Los Angeles; and Palo Alto, California.

With a Verizon 5G small cell lurking overhead, software maker Proximie, based in Bedford, Massachusetts, demonstrated its cloud-based, augmented reality-capable telemedicine platform on a high-resolution screen with multiple livestreams — as many as three upload and six download streams running at about 10 to 12 megabits per second each.

A Proximie product manager moved her hand across a blank tabletop in front of a camera, and the screens showed the hand overlaid on a cutaway model of a mock patient’s midsection. It illustrated how a doctor in LA could provide AR input to a surgeon performing an operation in New York without lag or dropped signal. The system could also allow, say, radiology images to be matched up with the view of the patient.

“Once it’s rolled out, it’s gonna change the game,” said Auri Vizgaitis, Proximie’s lead software architect.

“5G lets us get more computing off the device,” said Rahul Chipalkatty, CEO of Boston-based robotics software maker Southie Autonomy.

But even with these industrial applications in mind, there’s still a spot for 5G-enabled smartphones. Pittsburgh-based robotics company RealBotics demonstrated how 5G could help get factory employees up to speed on managing robots, through a combination of smartphone speed, low latency, HD video and augmented reality via edge computing.

The advances these companies are envisioning — highly capable autonomous cars, far-flung surgeons collaborating in real time, the internet of things working in high gear — are the future that 5G’s been dangling in front of us for a while now, and probably will for some time still to come.

“It will exist at some point in the future,” said Palmer. “This lab is about how do you innovate on top of that network.”

India’s 5G may lag due to low telecom infrastructure growth rate and insufficient fiber for backhaul

by Muntazir Abbas (edited by Alan J Weissberger) from Economic Times:

India’s 5G ambition may be thwarted as mobile infrastructure expansion is likely to remain low-paced following policy bottlenecks in the federal governance structure.  Add to that India’s weak fiberization, which is mandatory for high-speed wireless network backhaul.

The country’s existing telecom infrastructure catering to a billion active subscribers may require rapid expansion, but the absence of clarity on active network sharing, distributed right-of-way norms and thin fibre penetration, may not bring 2020 a true 5G year.

The Narendra Modi-led government is eyeing to make 5G services commercially available by next year after soon-to-start field trials which would be followed by a mega spectrum sale with 275 Mhz of airwaves earmarked for the newer technology.

Plagued with high debt, the telco incumbents  Vodafone Idea and Bharti Airtel, have not made much network investments over the past few years.  In a constrained scenario, sharing of active and passive networks assume much significance.

The Tower and Infrastructure Providers Association (Taipa) Director General Tilak Raj Dua says, “In order to make 5G a success story in India, it is essential to invest on network densification heavily through provisioning of fiber, small cells and mobile towers.”  Taipa represents telecom infrastructure companies in the country.

The India Department of Telecommunications (DoT), over the past few years, has apparently not been able to bring telecom tower companies to mainstream despite their ever-growing role in India’s digital service delivery.

The much-sought ‘infrastructure status’ accorded to the sector in 2012, has not materialised so far with firms seeking the Narendra Modi government to bring about radical reforms before the 5G make a debut.

Fiberization— A must do

Fibre-based backhaul is still in infancy in India. Industry’s assessment suggests that India’s robust 5G network would require 100 million fibre kilometres (m fkm) optic-fibre cable a year which has been growing at merely a rate of nearly 25 mfkm a year currently.

The government has recognized it as the strategic element for a high-speed data network, and has put a huge thrust and aims to increase fibre footprint to five fold or 7.5 million kilometres by 2022, from the current 1.5 million kilometers. In addition, the national policy aims to fiberise at least 60% of telecom towers by 2022, eventually accelerating migration to 5G.

“Achieving such speeds make fiber connectivity essential. India’s high population density also translates into deeper and denser fiber network,” ratings agency ICRA in its finding said, adding that the country has about 500,000 towers of which only 22% are fiberised as against 80% in China.

Earlier, telecom secretary Aruna Sundararajan said that that the department would want to benchmark how much fibre is being deployed every day to achieve 4G and 5G, and it has to become a national priority, and added that if the industry ever wants to take 5G to the villages without fibre, it would not happen, as fiberisation remains a key driver.

State-run Bharat Sanchar Nigam Limited (BSNL) that has the largest fibre base of up to 8 lakh kilometres is considering to lease out dark fibre to private players in a run up to 5G rollout that according to analysts would help operators cut Capex by leveraging state telco’s infrastructure as per need basis.

ICRA estimates the present market value of fiber assets owned by major private telecom operators stand at nearly Rs 1.25 lakh crore, with the extent of fiber rollout over the next few years would require investments of Rs 2.5 lakh crore to 3 lakh crore and sharing of fiber among multiple telcos would be the driver for a reasonable return on capital.

“5G rollout is the biggest driver for all major investment into fibre infrastructure in next five years. The next generation of technology’s performance will be dependent on the overflow of content to and from data centres,” Sandeep Aggarwal, Managing Director of Paramount Communications said, and added that the only medium capable of meeting these demands is fiber which will need to be available at every nook and corner of the country.

The government, in a recently-unveiled national policy also talked about setting up of a National Fibre Authority (NFA), but ironically there has been a dismal activity so far to take the ambitious vision forward.

The challenges, from the fibre standpoint, however, continue to remain making the 5G ride not so smooth with fibre companies together with telecom carriers seeking the Narendra Modi-led government to accelerate efforts and carve out an incentive regime.

Reliance Jio, a pure-play 4G operator that has up its ante in fibre deployment for the ambitious fibre-to-the-home (FTTH) offering dubbed as JioGigaFiber said that that to incentivise telcos, the department should draw out incentives so that operators are not challenged to deliver on fiber which is a critical element for India’s digital growth.

Earlier, Mumbai-based Jio chief Mathew Oommen said that, “service providers should use incentives for creating a deeper fiber with the redundancy of routes,” and believes that incentives should be in the form of “conducive policy to attract more investments in building fibre infrastructure” by telcos.

“5G is an interesting initiative. There is still a lag in fiber deployments in remote locations. We have learnt how to roll out fiber throughout the country, and modern technologies aligned to 5G is also one of the important factors,” R&M chairman Hans Hess told ETT.

“5G needs fiber highways and tower fiberisation is essential to be accelerated and the establishment of National Fiber Authority similar to the National Highway Authority or NHAI. These aim towards a significant portion to be invested in fibre roll out,” Sterlite Technologies Limited (STL) Group CEO Anand Agarwal told ETT.

Company’s top executive said that the national policy has accorded fibre the status of a public utility, and since fibre is essential for both wireline and wireless networks, a greater level of confidence in fibre investment was much needed.

R&M’s Hess seconded Agarwal’s views, adding that a robust fibre-based backbone would be a vital element for a network of next generation of networks.

“There would be an increase in consumption of data due to the Internet of Things (IoT) proliferation. In order to produce more data faster, a strong backbone is needed that can be built on fiber,” the Swiss company’s executive added.

“5G technology will also require a multi-fold increase in small cells deployment, with each small cell having backhaul on fibre. We are woefully inadequate in terms of optic-fibre cable density both in urban and rural areas and a special focus for its densification in a time bound manner is essential for 5G deployments,” Agarwal added.

India’s fiber coverage in kilometre per capita works out to 0.09, which is far behind 0.87 for China and more than 1.3 for the United States and Japan, according to ICRA.

The Gurugram-based firm believes that fiber density in India would have to increase at least four-fold, and that would also mean that it would evolve as a separate industry in some time, similar to the telecom tower segment in the past two decades.

Active network sharing— Do it now

The 5G, based on low latency technology, requires a dense network to seamlessly deliver Internet connectivity enabled through a telecom infrastructure such as in-building solutions, small cells, fiber and fiberised mobile towers.

In a view to ease out financially-stressed operators, the government, in the policy has envisaged active network sharing that would allow telcos to share their networks and thereby reducing their capital (Capex) as well as operational (Opex) investment. Currently, the contours of the new regime are under a discussion stage together with the department and industry, and is expected to bring much respite to 5G rollouts.

The national policy, however, talks about encouraging sharing of active infrastructure by enhancing the scope of Infrastructure Providers (IP) and promoting deployment with incentives for common sharable, passive as well as active infrastructure.

“This (active network sharing) should be done in a more structured manner. All telecom service providers should make active sharing as freely as possible that could also help them reduce Capex as well as Opex in a scenario where margins are thin,” BSNL Chairman Anupam Shrivastava said.

Shrivastava further said that it would be going to help all service providers, and added that BSNL was offering its network for sharing and the same was expected from other operators.

Sector watchdog Telecom Regulatory Authority of India (Trai), in one of its whitepaper estimates the savings on account of active infrastructure sharing to the extent of 25-35% in Opex and 33-35% in Capex.

Network sharing, according to industry analysts, can significantly bring down 5G networks rollout as well as maintenance cost. New York-based McKinsey & Company in its finding has estimated the cost reduction of up to 40% — with major savings in rollout of small cells.

Current telecom infrastructure growth rate may play spoilsport to India’s 5G party5G network, according to Taipa’s director general Dua, will enable a new set of applications such as the connected devices and cars which could become a reality only if the coverage becomes ubiquitous.

In order to have a pervasive 5G and for contiguous operations, there would have to be mushrooming of small cells over a city. Infrastructure providers can play a vital role in faster deployment of small cells that comes with a huge investment and thus support telcos to save on Capex and Opex,” he added.

Telecom carriers with 5G ambitions would be able to leverage 4G unified license (UL) coverage through dual connectivity or UL-sharing and would be able to cover larger areas with the same number of sites. 5G coverage compared to 4G coverage using 1800 MHz (megahertz) spectrum band would be about 60%.

A greenfield 5G operator, according to Taipa estimates, would need to deploy about 66% more sites to compensate for penetration losses.

Right-of-way— Not so right

The industry, demanding ease in Right-of-Way (RoW) rules, has been under continuous discussions with the regulator as well as policymakers for shaping up a comprehensive ‘dig-once’ common duct policy framework that according to the industry would help in the proliferation of 5G infrastructure across the country.

The next generation technologies are shaping the world economies and the smart cities would be built on a fibre-centric network for enabling ubiquitous and seamless connectivity. Trai is expected to come out with a policy enabling ‘common duct’ that would take telecom infrastructure to a next-level of growth.

In the last two years, post industry’s continuous rigorous follow-ups, only 13 states have to some extent aligned their policies with the Centre’s RoW rules notified in November 2016, according to Taipa.

“There is an urgent need for the states to align their telecom infrastructure policies with the Indian Telegraph Right of Way Rules to facilitate deployment of mobile infrastructure and connect the unconnected,” Dua added.

Deployment of small cells is significant for a proliferation 5G in India, the network rollout would have to be facilitated through enabling policies, which, according to the group, should include mandatory provisions for small cells at government lands and premises with new business models to excite municipal corporations and state governments.

The infrastructure providers such as Bharti Infratel, ATC Corporation and GTL Infrastructure demand a uniform RoW charges and single-window clearances nationwide to facilitate the telecom infrastructure for the digital delivery of services as envisaged by the Centre.

GSA May Update: Gigabit LTE – Global Status

Editor’s Note:

Gigabit LTE will be the backbone of support for (3GPP Release 15) 5G NR-NSA as it’s used for signaling, evolved packet core (EPC), and network management.  5G with low latency, signaling and a 5G mobile packet core won’t be deployed in mass till IMT 2020 standard has been completed.

INVESTMENT IN GIGABIT LTE NETWORK TECHNOLOGIES WORLDWIDE:

  • At the end of February 2019, GSA has identified 101 operators in 60 countries or territories investing in all the three core LTE-Advanced features for Gigabit LTE (defined as Carrier Aggregation, 4×4 MIMO or higher, and 256 QAM modulation in the downlink)
  • 53 operators have deployed all three of these technologies and / or launched commercial services based on them
  • 313 operators in 133 countries are investing in at least one of the key technologies

DISTRIBUTION OF GIGABIT LTE NETWORKS AND DOWNLINK SPEEDS OF THE FASTEST NETWORKS:

Gigabit LTE does not always equal Gigabit speed. Some networks capable of delivering 1 Gbps downstream do so without using all three key LTE-Advanced (AKA IMT Advanced in ITU-R) features; some networks using all three features do not achieve 1 Gbps

The fastest networks in the GSA database are:

  • KDDI, SK Telecom, Swisscom, Telus, Turkcell:  1.2 Gbps
  • KT: 1.167 Gbps(achieved using MPTCP to combine LTE with 3CA and WiFi)
  • China Unicom:  1.156 Gbps
  • Bell Mobility:  1.15 Gbps
  • 3 Hong Kong, Singtel:  1.1 Gbps
  • Optus: 1.03 Gbps
  • Vodafone Italy:  1.023 Gbps

Key findings in OpenSignal’s “State of the Mobile Network Experience” report

According to a new OpenSignal report, South Korea is well ahead of any other country in the world when it comes to Download speed experience, with average speeds topping 50 Mbps.   Only Norway comes close, with even third-placed Canada a clear 10 Mbps behind.  OpenSignal saw a huge range of scores in this metric, with the lowest average score being less than 2 Mbps.

Download Speed Experience_Opensignal State of Mobile Network Experience 2019

The biggest variation between Upload speed experience scores of our users was at the top end of the table, where the gap between leader Denmark and tenth-placed Canada was over 5 Mbps.

In only 13 of the 87 countries we rated our users averaged Latency experience scores under 40 milliseconds, while none scored under 30ms. One continent dominated our Latency Experience analysis, with six European countries in our top 10.5G’s designers target much improved latency as one of their goals.

At the other end of the scale we inevitably have developing countries, but it’s surprising to see India still lagging at 6.8 Mbps average despite all the investment from Reliance Jio, which has been focused on coverage rather than speed.   India is doing a lot better in terms of 4G availability. The average Indian mobile user has access to 4G about 91% of the time according to OpenSignal.

Only four European countries made OpenSignal’s 4G Availability top 10 — the fewest of any of our award metrics. And both the U.S. and India made the top 10, despite being distinctly mid-table in all other key metrics.  One of the standout countries to feature in the top five of our 4G Availability rankings was the U.S. which was distinctly mid-table across all other key award metrics but managed a fifth-place finish in 4G Availability. In our most recent Mobile Network Experience USA report, we saw Verizon overtake T-Mobile following a fierce battle in this metric. This rivalry has driven up 4G Availability in the country, leading to a world-class position for the U.S. in our rankings.

4G Availability_Opensignal State of Mobile Network Experience 2019

Indeed, 4G is becoming more and more ubiquitous, even in developing markets. OpenSignal’s analysis shows that the average 4G Availability
across the 87 countries experienced by our users is close to 80%, with 15 markets scoring over the 90% mark. The top ends of our tables were
largely dominated by European countries, but no one country appeared in the top 10 for all five of our key metrics. European countries, however,
dominated, racking up far more top 10 entries than any other region.

In a ranking of the 10 countries who scored highly across all five key metrics, only two were from outside Europe.

Comparison of leading countries in Opensignal key metrics_Opensignal State of Mobile Network Experience 2019

Norway was #1 in the Video Experience category despite of being even worse than Korea when comes to latency.  Hungary was #2.  Astonishingly,  only six non European countries among the top 25 who all scored a Very Good rating (65-75 out of 100).

5G should mean more consumers will be able to enjoy a good mobile Video Experience more often because of the increased mobile capacity new high frequency 5G spectrum will provide to mobile operators.

MEF SD-WAN Service Standard Now Publicly Available; ITU-T SD-WAN Work a Dead End?

MEF SD-WAN Service Attributes & Services Standard:
The new MEF spec defines a SD-WAN service and its various attributes – the first time any standards body or forum has done this.  MEF got involved in the SD-WAN interoperability a few years ago, as part of its MEF 3.0 Global Services Framework.  It hoped to bring some order to a space where every SD-WAN vendor was defining its product and services a differently with no accepted definition of what a SD-WAN was or any inter-operablity (no UNI or NNI).

After incorporating extensive feedback from service providers and technology vendor members, MEF is now moving the draft SD-WAN Service Attributes and Services standard (MEF 70) through the last phase of MEF membership and Board approval. The document is available for download here.

“MEF’s team of SD-WAN experts has worked overtime to develop a robust and timely industry standard following multiple rounds of in-depth peer review,” said Pascal Menezes, CTO, MEF. “We will officially publish MEF’s SD-WAN service standard by mid-July 2019, but we are making the final draft publicly available now because broad industry alignment on common terminology will be healthy for market growth.”

MEF’s SD-WAN service definition standard describes requirements for an application-aware, over-the-top WAN connectivity service that uses policies to determine how application flows are directed over multiple underlay networks irrespective of the underlay technologies or service providers who deliver them.

SD-WAN service relies on two or more network connections, directing traffic over one connection or the other based on pre-defined parameters, traffic levels and other variables. For example, a company might use an MPLS VPN and a direct internet connection, with mission-critical traffic routed over the MPLS connection, while less critical traffic travels over the internet connection.

MEF defines the SD-WAN UNI, or User to Network Interface, as the point of demarcation between the service provider network and the enterprise network, determining where each party’s functionality and responsibility ends. SD-WAN Edge defines the services available on the customer premises, which could be available through on-premises equipment or in the cloud. And the Underlying Connectivity Service, or UCS, is the underlay wide-area network, typically MPLS, LTE, cable broadband — likely in combination — and possibly from multiple vendors. Additionally, MEF defines the Tunnel Virtual Connection (TVC) as overlay tunnels that are built over the UCS, which provide interconnects between locations.

In summary, the MEF SD-WAN service standard introduces four relevant SD-WAN terms:

  • SD-WAN UNI (user-network interface)
  • SD-WAN Edge, where SD-WAN functionality is achieved, which could be a physical or virtual appliance such as a virtual network function in the cloud
  • Underlay connectivity service (UCS), which is the wide area network service such as MPLS or IP
  • Tunnel virtual connection (TVC), the connection created over the underlay network

SD-WAN Service Constructs:

MEF SD-WAN Service Constructs May 2019-2

Definitions:
SD-WAN Edge:  Physical or virtual
SD-WAN Controller: Centralized management of SD-WAN edges & gateways
Service Orchestrator: Lifecycle Service Orchestration (LSO) of SD-WAN and other services
Subscriber Web Portal: Subscriber service ordering and modification
……………………………………………………………………………………………………

Standardization will enable a wide range of ecosystem stakeholders to use the same terminology when buying, selling, assessing, deploying, and delivering SD-WAN services. The SD-WAN service definition is a foundational step for accelerating sales, market adoption, and certification of MEF 3.0 SD-WAN services orchestrated across a global ecosystem of service provider networks.

Next Steps for SD-WAN Service Standardization: 

MEF already has begun work on the next phase of SD-WAN standardization (MEF 70.1), which covers more complex service attributes related to application business importance and prioritization, underlay network characteristics, and connectivity to private/public cloud services consistent with market priorities for SD-WAN services. MEF also is progressing standards work focused on LSO (Lifecycle Service Orchestration) APIs, application security, and intent-based networking for SD-WAN services.

Pilot MEF 3.0 SD-WAN Service Certification:

MEF remains on track to launch its pilot MEF 3.0 SD-WAN Service Certification program in 2019. This certification will test a set of service attributes and their behaviors defined in the SD-WAN standard and described in detail in the upcoming MEF 3.0 SD-WAN Service certification Blueprint. Service and technology companies interested in participating in the pilot should contact Alysia@mef.net

ITU-T SD-WAN work item:

ITU-T has a SD-WAN work item under study, but as far as I can tell, there is no output yet.  The project is named Signalling Requirement for SD-WAN service.

Summary: SD-WAN is an ecosystem of hardware (including customer-premises equipment, such as edge devices), software (including controllers), and services that enables enterprise-grade WAN performance, reliability, and security in a variety of ways. This Recommendation specifies signalling requirements for SD-WAN service. The signalling is to support the dynamically set up and manage the enterprise WAN connections.

The three contacts for this work all are from China Mobile.  Following are highlights from an unapproved draft spec:

Introduction:

[ITU-T Editor’s note in September 2018] It is needed to provide the difference between two types of SD-WAN, one is provided by enterprise itself, the other one is provided by the carrier. This Recommendation address the latter. Contributions are invited.

  • The SD-WAN services could be provided by two types of providers. One type is the enterprise and the other is carrier. This Recommendation addresses the latter. The main differences between the two types are shown as below:Network performance monitoring and statistic collection: The enterprise launched service is only able to monitor the performance parameters of its own end-to-end path. While the carrier launched service is capable of monitoring not only the enterprise specific path but also the performance of the whole network. The over view of the network is more helpful for carrier to plan the end-to-end paths for thousands of enterprise as a whole.
  • Service provision: when the path need to be switched over, the enterprises only has the authority to configure the CPE. If they need to change the path in core network, they have to ask the carrier to do so. In contrast, the service which is launched by carrier can be quickly changed by saving the communication time between enterprise and carrier.

The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below.

Huawei Ban Threatens Wireless Service in U.S. Rural Areas

“It’s really frustrating,” said Kevin Nelson was recently in the middle of his 1,538 ha farm in north-east Montana, about the poor cellular reception. “We keep being told it’s going to improve, it’s going to improve.”  NOT LIKELY ANY TIME SOON!

Plans to upgrade the wireless service near Mr Nelson’s farm halted abruptly this month when US President Donald Trump issued an executive order that banned the purchase of equipment from companies “posing a national security threat.”  That order was meant to bar network equipment from Huawei, the Chinese telecommunications giant, which is a major supplier of equipment to rural wireless companies.

The CEO of the wireless provider in Mr Nelson’s area said that without access to inexpensive Huawei products, his company could not afford to build a planned tower that would serve Mr Nelson’s farm.  Nowhere will the changes be felt more acutely than in rural America, where wireless service is spotty despite years-long government efforts to improve coverage. They also add to the economic uncertainty created by the White House’s trade war with China. Farmers are fearful of an extended hit to their exports.

Huawei is essential for many wireless carriers that serve sprawling, sparsely populated regions because its gear for transmitting cell signals often costs far less than other options.

Mr Trump’s ban is forcing carriers such as Nemont, which serves Opheim, to scrap expansion plans. In addition, some of the companies already using Huawei equipment fear that they will no longer receive government subsidies meant to help get service to remote areas.

U.S. intelligence officials have accused Huawei of being an extension of the Chinese government, and said that its equipment could be vulnerable to espionage and hacking.  President Trump also appears to be using Huawei as a bargaining chip in his escalating trade battle with China. “Huawei is something that is very dangerous,” he said last Thursday. “It’s possible that Huawei would be included in some kind of trade deal.”

Huawei has denied that it is a security risk, saying that it is an independent business that does not act on behalf of the Chinese government. It said that 500 carriers in more than 170 nations use its technology.  “Restricting Huawei from doing business in the US will not make the US more secure or stronger,” Huawei said in a statement. “Instead, this will only serve to limit the US to inferior yet more expensive alternatives.”

Much of Mr Trump’s focus has been on the next generation of wireless technology, known as 5G. But Huawei already provides equipment to about a quarter of the country’s smallest wireless carriers. The Rural Wireless Association, a trade group that represents 55 small carriers, estimated that it would cost its members US$800 million to US$1 billion to replace equipment from Huawei and ZTE, China’s other maker of networking gear.

Nemont, based near Opheim, is one of those companies. Its footprint is 36,260 sq km, bigger than Maryland, and requires huge amounts of wires, towers and other costly infrastructure. But the company has only 11,000 paying customers.  Nemont first reached out to Huawei nine years ago, when its members decided to upgrade their cellular network. With subsidies from the federal government, Nemont was prepared to spend about US$4 million on networking equipment such as routers and other gear to put on dozens of cell towers across the region.

Even at the time, officials in the Obama administration voiced concerns about Chinese equipment makers and their ability to break into US networks to steal intellectual property or hack into corporate or government networks. Defense Department officials and lawmakers said that they were concerned that the Chinese government and military could use the equipment to intercept American communications.

The officials were vague about their concerns over Huawei, then a little-known firm. But Mike Kilgore, the chief executive of Nemont, said that he had outlined Nemont’s plans to buy Huawei equipment in a letter to Senator Jon Tester, and asked whether Mr Tester had security concerns.  Mr Kilgore said that he was ready to go another route if Huawei’s equipment would put customers at risk. “I was begging for them to say, ‘No, don’t buy it,'” he said.

Mr Tester’s office called him and said that it did not see any major concerns with picking Huawei, Mr Kilgore said. A spokesman for Mr Tester said that an aide had told Mr Kilgore to contact the Federal Bureau of Investigation (FBI) and other intelligence officials for advice.  After the call, Mr Kilgore chose Huawei, which offered to customise its equipment and charge 20-30 per cent less than competitors.

…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………….

Nemont has since expanded its high-speed wireless network using almost all Huawei equipment. Mr Kilgore even visited Huawei’s headquarters in Shenzhen, China. He is the president of the Rural Wireless Association, the trade group. Huawei has a representative on the group’s board without voting rights, one of two board members who do not represent a wireless carrier.

“The other vendors hardly gave us the time of day, and now they have been acquired or are out of business,” Mr Kilgore said. “We took a gamble, but we clearly made the right bet.”

The technological upgrade changed lives. Kevin Rasmussen was recently in the cab of his tractor using an iPad connected to high-speed Internet beaming from a nearby cell tower. The connection worked with software on the iPad to help direct where the tractor poked holes in the soil and dropped seeds and fertilizer.

“I can sit up here in my tractor and do my banking, monitor six weather apps and read up on things like trade and Huawei, all on my phone,” Mr Rasmussen said. “Rural America needs this so badly.”

Many companies that extend wireless broadband to rural areas, like Nemont, depend on subsidies from the Federal Communications Commission (FCC). Ajit Pai, the FCC’s chairman, has proposed cutting off that money to carriers using equipment from Huawei or ZTE.

“We believe that it is important that networks are secure not just in urban areas, but in rural areas as well,” the agency said in a statement. “There are currently many rural broadband providers that use equipment that does not pose a national security risk.”

Mr Kilgore estimated that it would cost US$50 million to replace his Huawei equipment. If that is the only option, he said, he might have to shut down the company, leaving his customers without wireless service.  Mr Rasmussen said that would be a big blow to his farming operation. “We’re getting squeezed on all sides,” he said. “The tariffs and trade affect our prices, and now this could affect our ability to farm.

Pre-Pub Version of ITU-T G.9701-2019: Fast access to subscriber terminals (G.fast) – Physical layer for copper wire or coax cables

Overview of ITU-T G.9701-2019 (as of May 24, 2019):

Summary:

1.  Previous version: Recommendation ITU-T G.9701-2014 specifies a gigabit broadband access technology that exploits the existing infrastructure of copper wire-pairs that were originally deployed for plain old telephone service (POTS) services. Equipment implementing this Recommendation can be deployed from fibre-fed distribution points (fibre to the distribution point, FTTdp) located very near the customer premises, or within buildings (fibre to the building, FTTB). This Recommendation supports asymmetric and symmetric transmission at an aggregate net data rate up to 1 Gbit/s on twisted wirepairs using spectrum up to 106 MHz and specifies all necessary functionality to support far-end crosstalk (FEXT) cancellation between multiple wire-pairs, and facilitates low power operation.

2. Recommendation ITU-T G.9701-2019 integrates ITU-T G.9701-2014 and all of its corrigenda and amendments, and adds support for the following new functionality: LPM classes, optional extension of probe sequence length, short CLR/CL messages, Annex R – Showtime reconfiguration, and Appendix IV – Targeted generalized vectoring with active G.9701 supporting lines (TGVA). It also adds several clarifications, and fixes various errors and inconsistencies including ANDEFTR support, SRA triggering and PMS-TC parameter requirements, and conditions for an rtx-uc anomaly.

Scope:

This Recommendation specifies the operation of a broadband access technology that exploits the existing infrastructure of wire-pairs that were originally deployed for plain old telephone service (POTS) and, with Amendment 3, adds support for operation over coaxial cables.

This Recommendation supports transmission at an aggregate net data rate (the sum of upstream and downstream rates) up to approximately 2 Gbit/s.

While asymmetric digital subscriber line transceivers 2 (ADSL2) – extended bandwidth (ADSL2plus) uses approximately 2 MHz of the spectrum, and very high speed digital subscriber line transceivers 2 (VDSL2) uses up to 35 MHz of the spectrum, this Recommendation defines profiles using spectrum up to 106 MHz and 212 MHz and specifies all necessary functionality to support the use of far-end crosstalk (FEXT) cancellation between ITU-T G.9701 transceivers deployed on multiple wire-pairs. The availability of spectrum up to 106 MHz or 212 MHz allows ITU-T G.9701 transceivers to provide reliable high data rate operation on very short loops. This Recommendation can be deployed from fibre-fed distribution points located very near the customer premises, or within the buildings. This Recommendation is optimized to operate over wire-pairs up to approximately 250 m of 0.5 mm diameter. However, it is capable of operation over wire-pairs up to at least 400 meters of 0.5 mm diameter, subject to some performance limitations.

This Recommendation defines a wide range of settings for various parameters (such as spectral usage and transmitter power) that may be supported by a transceiver. Therefore, this Recommendation specifies profiles to allow transceivers to support a subset of the allowed settings and still be compliant with the Recommendation. The specification of multiple profiles allows vendors to limit the implementation complexity and develop implementations that target specific service requirements. This edition of the Recommendation specifies transmission profiles for inband spectral usage of up to 212 MHz and maximum transmit power up to +8 dBm. This Recommendation operates in compliance with the power spectral density (PSD) specification in [ITU-T G.9700].

As per ITU-T Recommendations in the ITU-T G.99x series, this Recommendation uses [ITU-T G.994.1] to initiate the transceiver training sequence. Through negotiation during the handshake phase of the initialization, the capability of equipment to support this Recommendation and/or ITU-T G.99x series Recommendations (e.g., [ITU-T G.993.2] defining VDSL2) is identified. For reasons of interoperability, equipment may support multiple Recommendations such that it is able to adapt to the operating mode supported by the far-end equipment.

It is the intention of this Recommendation to provide, by negotiation during the initialization, U interface compatibility and interoperability between transceivers complying with this Recommendation, including transceivers that support different combinations of options. The technology specified in this Recommendation provides the following key application features:

• Best aspects of fibre to the home (FTTH): up to 2 Gbit/s aggregate net data rate;
• Best aspects of ADSL2: customer self-install and operation in the presence of bridged taps, avoiding operator truck-rolls to the customer premises for installation and activation of the broadband access service;

• Coexistence with ADSL2 and VDSL2 on adjacent wire-pairs;
• Low power operation and all functionality necessary to allow transceivers to be deployed as part of reverse powered (and possibly battery operated) network equipment and to adapt to environmental conditions (e.g., temperature);
• Management capabilities allowing transceivers to operate in a zero touch deployment, avoiding truck-rolls to the network equipment for installation and activation of new or upgraded broadband access service;
• Control of the upstream vs downstream transmission time to adapt net data rates to the needs of the business and the residential customers;
• Vectoring (self-crosstalk cancellation) for increased net data rates on wire-pairs that experience far-end crosstalk from ITU-T G.9701 transceivers in the same vectored group operating on other wire-pairs in the same cable or operating on other wire-pairs originating from the same network equipment;
• Network timing reference (NTR) and time-of-day (ToD) transport for network frequency and time synchronization between network and customer premises equipment;
• Configuration of spectrum use, including configuration of the transmit power spectral density (PSD) limitations and notches to meet electromagnetic compatibility (EMC) requirements.

The technology specified in this Recommendation uses the following key functionalities and capabilities:
• Transparent transport of data packets (e.g., Ethernet packets) at an aggregate (sum of upstream and downstream) data rate of up to 2 Gbit/s;
• In-band spectral usage up to 212 MHz;
• Configurable start and stop frequencies, PSD shaping and notching;
• Discrete multitone (DMT) modulation (2 048/4 096 subcarriers with 51.75 kHz subcarrier
spacing);
• Time-division duplexing (sharing time between upstream and downstream transmission);
• Low latency retransmission, facilitating impulse noise protection (INP) between the V and T reference points at all data rates to deal with isolated erasure events at the U reference point of at least 10 ms, without loss of user data;
• Forward error correction based on Trellis coding and Reed-Solomon coding;
• Vectoring (self-FEXT cancellation), where this edition of the Recommendation uses linear precoding;
• Discontinuous operation where not all of the time available for data transmission is used;
• Online reconfiguration (OLR) for adaptation to changes of the channel and noise characteristics, including fast rate adaptation (FRA).

With these functionalities and capabilities, the technology specified in this Recommendation targets the following aggregate net data rates over a 0.5 mm straight wire-pair for 106 MHz profiles:
• 500 to 1000 Mbit/s on a wire-pair shorter than 100 m;
• 500 Mbit/s at 100 m;
• 200 Mbit/s at 200 m;
• 150 Mbit/s at 250 m;
• 500 Mbit/s at 50 m, while operating in the band above 17 MHz.

Germany’s Contentious 5G Auction May Squeeze Telcos

Germany’s auction of 5G frequencies, now into its 10th week, has drawn 6 billion euros ($6.7 billion) in bids so far.  That amount raised in a record 405 auction rounds for the 41 blocks on offer is more than experts thought companies would spend all together for all rounds.   The duration of this auction has no precedent in Germany, with country’s 4G auction in 2010 lasting for 224 rounds.

German telco market leader Deutsche Telekom has complained that the regulator has forced up prices by offering too little spectrum.  Deutsche Telekom leads in 13 of the blocks, with competitor Vodafone ahead in 12 and Telefonica Deutschland in eight, according to auction results published by the Federal Network Agency (BNetzA).

Source:  Deutsche Telekom

……………………………………………………………………………………………………

New entrant 1&1 Drillisch, a ‘virtual’ mobile player controlled by United Internet, leads in eight blocks, as billionaire CEO Ralf Dommermuth pursues his dream of becoming Germany’s fourth operator.

Drillisch, and United Internet, have slashed their dividend payouts to conserve cash so that they can stay in the game.

As the telecom industry prepares for the costly rollout of new 5G networks, with little prospect of any immediate revenue growth from new 5G services, the spectrum bill is a further squeeze. And while bidding has recently slowed, the contest is not yet over.

Industry leaders say that inflated auction costs would undermine their ability to invest the billions needed to build 5G networks – as happened in a pricey spectrum auction in Italy last year.

………………………………………………………………………………………………………….

German telcos appear to be grasping expensively for a small amount of spectrum in the 3.6GHz range, the “mid-band” that looks optimal for the delivery of 5G services. The fight would have been less damaging and drawn-out had German regulators put more of these airwaves up for sale, according to Timotheus Höttges, the head of Deutsche Telekom.  Instead, they chose to hold back 100MHz for industrial and local settings, such as German factories, leaving 300MHz to the telcos. Supply constraints have driven up the bids.

Competition has been especially fierce because of 1&1 Drillisch. Having previously bought network capacity from Telefónica, and functioned as a mobile virtual network operator, the broadband company is now determined to build a fourth mobile network using spectrum it picks up in the auction. After round 406, 1&1 Drillisch accounted for more than €1.1 billion ($1.2 billion) of the amount bid. Since the auction began, its share price has lost a quarter of its value as investors worry about the consequences of spending so much.

Outside Italy, Germany now values the mid-band at a higher level than any other European country that has licensed 5G spectrum. Were the auction to finish now, German telcos would pay about $0.16 per megahertz per head of population (per MHz pop, a common way of valuing spectrum) for 3.6GHz licenses. That edges Germany ahead of the UK, which raised about $0.15 (at current exchange rates) per MHz pop during a 3.4GHz auction in 2018. Spanish companies last year paid just €0.05 during a 3.6-3.8GHz auction (although this calculation does not consider usage fees they are also charged). Finland’s mid-band sale in October raised as little as $0.04.

However, the German auction is nowhere near Italy on this measure, and it will not even get close. After slapping just 200MHz of mid-band spectrum on the table, and slicing it like a badly cut pizza into uneven segments, Italian regulators made off with around $0.40 per MHz pop. The auction “winners” are now choking on their rewards. Telecom Italia and Vodafone, which landed the biggest mid-band concessions, are busy slashing jobs and pooling assets to ensure 5G rollout is affordable.

German telecom regulator Jochen Homann, the president of the Bundesnetzagentur, is said to have argued that bidders knew the conditions of the auction before it started and will have prepared accordingly. Yet analysts thought a spectrum sale would raise between €3 billion ($3.4 billion) and €5 billion ($5.6 billion), an upper limit the auction has now breached.

Light Reading says German authorities may still have cause to worry. While the country’s operators are in healthier shape than Italy’s, a large spectrum bill risks slowing down the pace of 5G rollout and jeopardizing national ambitions. With its large manufacturing sector, Germany is hopeful that 5G will support Industrie 4.0, a government initiative to bring communications technologies into factories and the workplace. The productivity boost this promises may be critical if Germany is to remain competitive with the US, China and other fast-developing Asian countries.

In the U.S., the FCC auctioned off 24GHz high-band spectrum in March 2019, with the announcement of more spectrum sales expected in the coming months.  The U.S. has yet to allocate any mid-band spectrum.
