ETNO, GSMA: EU should adopt “fresh approach” to support fiber & 5G investments; GSMA says 5G SA coming soon?

The European telecom network operators industry group ETNO together with the GSMA have called on the EU to make support for fiber optics communications and 5G investments part of the bloc’s economic recovery plans. In a joint statement to mark the start of the German presidency of the EU, the associations said a fresh approach is needed to ensure the focus is on closing the digital divide and that plans to alleviate that should not become bogged down in regulatory discussions.

“We encourage all institutions to take stock of the socio-economic context and shift regulatory modes from ‘business-as-usual’ to a fresh and comprehensive approach aimed at unleashing the full power of network investment, at full scale and at full pace,” the statement said.

The joint communique then delineated ways policymakers can support the investment in improved connectivity for the EU:

  • Spectrum auctions are timely and conditions for spectrum assignment support network deployment. This includes taking a long-term view to spectrum prices, rather than imposing punitive fees that hamper 5G investment. Also, access and coverage obligations should not diminish the speed and scale of investment in network roll-out;
  • Sharing agreements for Radio Access Network (RAN) are supported and incentivised, so that they contribute to a speedy 5G deployment;
  • All fibre investment models are adequately incentivised at the national level, including co-investment and other forms of partnerships;
  • Innovative infrastructure solutions, such as cloud, edge and quantum computing, are given the appropriate support;
  • Future EU initiatives dramatically reduce roll-out costs for both mobile and fixed networks. This should tackle, for example, unreasonable costs for using public ground as well as complex authorization procedures for both fixed and mobile networks;
  • Open and interoperable interfaces in the RAN are supported. Initiatives such as Open RAN have the potential to support Europe’s multi-vendor approach, while reducing deployment costs, further strengthening the security of the equipment and unleash more network innovation.

The most important thing is helping grow adoption of the new technologies by citizens and businesses, the statement said. This includes supporting digital skills education and training. “Finally, workers of all ages should be put in the condition to develop the necessary digital skills – both through upskilling and reskilling – to thrive in innovative and fast-paced markets.”

Demand stimulus measures can also help bring digital services to public sector organizations like schools, hospitals and local administrations. That would not only support Europe’s economic recovery, but also can contribute to the EU’s climate goals.

The GSMA and ETNO also called on the EU governments to combat the attacks against telecom infrastructure and misinformation surrounding 5G. To date they have counted over 180 arson attacks against mobile antennas in 11 countries.

Separately, GSMA says “5G Stand Alone to Become Reality“:

“The deployment of fully virtualized networks using 5G Stand Alone Cores, thereby facilitating Edge Computing and Network Slicing, will enable enterprises and governments to reap the many benefits from high throughput, ultra-low latency and IoT to improve productivity and enhance services to their customers,” said Alex Sinclair, Chief Technology Officer, GSMA.

“5G Stand Alone Option 2 can meet various and more stringent requirements and provide optimal and differentiated solutions, thereby empowering more businesses and unlocking the potential of many services. 5G is changing our society and life,” said Liu Guiqing, Executive Vice President of China Telecom.

“NTT DOCOMO has been actively promoting virtualisation of our core network; we believe that this virtualisation technology is already mature and that our operational know-how will be our advantage. In the future we expect to build dedicated networks, optimised for consumer use cases, such as AR /VR and gaming,” said Hiroyuki Oto, General Manager of Core Network Development Department, NTT DOCOMO, Inc.

The latest version of the 5G SA guidelines ‘5G Implementation Guidelines: SA Option 2 will be released 30th June at 17:00 Beijing time during Thrive China, a new virtual event from the GSMA.

NOTE that those GSMA guidelines come before 3GPP Release 16 5G Architecture (including 5G Core) spec 23.501 is finalized/frozen at 3GPP’s July 2020 meeting.  It seems there will be many versions of 5G core networks:

Alex Quach, VP of Intel’s Data Platforms Group: “The way different service providers implement their 5G core is going to vary. Every service provider has unique circumstances. The transition to a new 5G core is going to be different for every operator.”

Asked if SK Telecom has now completed its 5G Standalone core network, the South Korean carrier was vague in an email reply to FierceWireless. “To commercialize standalone 5G service in Korea, we are currently making diverse R&D efforts including conducting tests in both lab and commercial environment. Our latest achievements include the world’s first standalone (SA) 5G data session on our multi-vendor commercial 5G network.

5G Stand Alone to Become Reality

 

NeoPhotonics demonstrates 90 km 400ZR transmission in 75 GHz DWDM channels enabling 25.6 Tbps per fiber

NeoPhotonics completed experimental verification of the transmission of 400Gbps data over data center interconnect (DCI) link in a 75 GHz spaced Dense Wavelength Division Multiplexing (DWDM) channel.

NeoPhotonics achieved two milestones using its interoperable pluggable 400ZR [1.] coherent modules and its specially designed athermal arrayed waveguide grating (AWG) multiplexers (MUX) and de-multiplexers (DMUX).

Note 1. ZR stands for Extended Reach which can transmit 10G data rate and 80km distance over single mode fiber and use 1550nm lasers.

  • Data rate per channel increases from today’s non-interoperable 100Gbps direct-detect transceivers to 400Gbps interoperable coherent 400ZR modules.
  • The current DWDM infrastructure can be increased from 32 channels of 100 GHz-spaced DWDM signals to 64 channels of 75 GHz-spaced DWDM signals.
  • The total DCI fiber capacity can thus be increased from 3.2 Tbps (100Gbps/ch. x 40 ch.) to 25.6 Tbps (400Gbps/ch. x 64 ch.), which is a total capacity increase of 800 percent.

NeoPhotonics said its technology overcomes multiple challenges in transporting 400ZR signals within 75 GHz-spaced DWDM channels.

The filters used in NeoPhotonics MUX and DMUX units are designed to limit ACI [2.] while at the same time having a stable center frequency against extreme temperatures and aging.

Note 2.  ACI stands for Adjacent Channel Interface; it also can refer to Application Centric Infrastructure.

What is 400ZR? - Ciena

NeoPhotonics has demonstrated 90km DCI links using three in-house 400ZR pluggable transceivers with their tunable laser frequencies tuned to 75GHz spaced channels, and a pair of passive 75GHz-spaced DWDM MUX and DMUX modules designed specifically for this application. The optical signal-to-noise ratio (OSNR) penalty due to the presence of the MUX and DMUX and the worst-case frequency drifts of the lasers, as well as the MUX and DMUX filters, is less than 1dB. The worst-case component frequency drifts were applied to emulate the operating conditions for aging and extreme temperatures, the company said in a press release.

“The combination of compact 400ZR silicon photonics-based pluggable coherent transceiver modules with specially designed 75 GHz channel spaced multiplexers and de-multiplexers can greatly increase the bandwidth capacity of optical fibers in a DCI application and consequently greatly decrease the cost per bit,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “These 400ZR coherent techniques pack 400Gbps of data into a 75 GHz wide spectral channel, placing stringent requirements on the multiplexers and de-multiplexers. We are uniquely able to meet these requirements because we do both design and fabrication of planar lightwave circuits and we have 20 years of experience addressing the most challenging MUX/DMUX applications,” concluded Mr. Jenks.

Windstream Wholesale and Infinera Complete Successful Trial of LR8-Based 400GbE Client-Side Services

Windstream’s Wholesale Division recently completed a 400 gigabit Ethernet (400 GE)  trial pairing the client-side transmission with 400GbE-LR8 QSFP-DD pluggable interfaces on Infinera’s platform.  Transmission used a single-carrier 600G wavelength, which the companies announced as an industry first.
Pluggables have gained momentum in optical technology as web-scale companies, service providers and data center operators look to deploy some 400G gear this year and even more next year.
“The ability to support 400GbE services with a wide-variety of client interfaces and to carry those services across metro, regional and long-haul distances enables Windstream to seamlessly support their customers’ evolving connectivity needs,” said Infinera’s said Glenn Laxdal, senior vice president and general manager of product management, in a press release.
Infinera’s 600-Gbps enabled Groove (GX) G30 Compact Modular Platform was used in the 400 GE trial.  A G30 version of the Groove was fitted with a 2x600G per wavelength muxponder via a CHM-2T sled. The 400GbE service was carried via a single-carrier 600-Gbps wavelength.Coriant, which originally developed the Groove platform, announced 600-Gbps capabilities for the system shortly before the company was acquired by Infinera in 2018 (see “Coriant adds 600G transmission to Groove via CloudWave T” and “Infinera closes Coriant acquisition”).

Nokia Bell Labs sets world record in fiber optic bit rates

Nokia Bell Labs announced that its researchers set the world record for the highest single carrier bit rate at 1.52 Tbps over 80 km of standard single mode fibre, the equivalent of simultaneously streaming 1.5 million YouTube videos – which is four times the market’s existing approximately 400 Gbps. The company said this world record, along with other announced optical networking innovations, will further strengthen its ability to create networks for the 5G era that meet the ever-growing data, capacity and latency demands of Industrial Internet of Things (IIoT) and consumer applications.

Several of these achievements were presented as part of Nokia Bell Labs’ post deadline research papers at the Optical Fiber Communications Conference & Exhibition (OFC) that took place during March 9-15, 2020 in San Diego, CA. In addition, Nokia Bell Labs researcher Di Che was awarded the OFC Tingye Li Innovation Prize.

The highest single-carrier bitrate at 1.52 Tbps was set by a Nokia Bell Labs optical research team led by Fred Buchali. This record was established by employing a new 128 Gigasample/second converter enabling the generation of signals at 128 Gbaud symbol rate and information rates of the individual symbols beyond 6.0 bits/symbol/polarization. This accomplishment breaks the team’s own record of 1.3 Tbps set in September 2019 while supporting Nokia’s record-breaking field trial with Etisalat.

Nokia Bell Labs researcher Di Che and his team also set a new data-rate world record for directly modulated lasers (DML), which are crucially important for low-cost, high-speed applications such as datacenter connections. The DML team achieved a world record data rate beyond 400 Gbps for links up to 15 km.

Marcus Weldon, Nokia CTO and President of Nokia Bell Labs, said:

“It has been fifty years since the inventions of the low-loss fiber and the associated optics. From the original 45 Megabit-per-second systems to more than 1 Terabit-per-second systems of today – a more than 20,000-fold increase in 40 years – to create the fundamental underpinning of the internet and the digital societies as we know it. The role of Nokia Bell Labs has always been to push the envelope and redefine the limits of what’s possible. Our latest world records in optical research are yet another proof point that we are inventing even faster and more robust networks that will underpin the next industrial revolution.”

In addition to these world records, Nokia Bell Labs researchers have also recently achieved significant achievements in optical communications, including:

  • The first field trial using spatial-division-multiplexed (SDM) cable over a 2,000km span of 4-core coupled-core fiber was achieved by researchers Roland Ryf and the SDM team. The experiments clearly show that coupled-core fibers are technically viable, offer high transmission performance, while maintaining an industry standard 125-um cladding diameter.
  • A research team led by Rene-Jean Essiambre, Roland Ryf and Murali Kodialam introduced a novel new set of modulation formats that provide improved linear and nonlinear transmission performance at submarine distances of 10,000 km. The proposed transmission formats are generated by a neuronal network and can significantly outperform traditional formats (QPSK) used in today’s submarine systems.
  • Researcher Junho Cho and team experimentally demonstrated capacity gains of 23% for submarine cable systems that operate under electrical supply power constraints. The capacity gains were achieved by optimizing the gain shaping filters using neural networks.

The researchers that achieved the world record and research results are part of Nokia Bell Labs’ Smart Optical Fabric & Devices Research Lab, which designs and builds the future of optical communications systems, pushing the state-of-the-art in physics, materials science, math, software and optics to create new networks that adapt to changing conditions and go far beyond today’s limitations.

Fiber optic cables, made of thin strands of glass, are used by #telecommunications companies to transmit telephone signals, Internet communication and cable television signals. These thin fibers are cabled and resemble pipes that carry information and data. #fiberoptics

Google Fiber drops 100Mb/s; Goes ‘All In’ on 1 Gig Internet Access

Google’s affordable, high-speed Fiber internet service has been around for quite some time, but only in select areas of the U.S. As it continues its very slow expansion to more cities and regions, Google is looking to streamline its operations by eliminating one of its only two Fiber based Internet access subscription plans.  Google Fiber is dropping its $50/month, 100Mb/s subscription for NEW CUSTOMERS.  100Mb/s FTTP has always been a slightly cheaper alternative to its 1 Gigabit plan, which is only $20 more at $70/month.

“Starting today, we’re recommitting to our roots. We’re going all in on a gig, just like we did all those years ago. We will no longer offer a 100Mbps plan to new customers,” Google said in a blog post.  “We are excited to turn our attention back to our gig service, still offered for $70/month—the exact same price it cost back in 2012 when we first launched,” Google added.

Currently, the Fiber service is available in 18 U.S. cities: Atlanta, Georgia; Austin, Texas; Charlotte, North Carolina; Chicago, Illinois; Denver, Colorado; Huntsville, Alabama; Kansas City, Missouri; Miami, Florida; Nashville, Tennessee; Oakland, California; Orange County, California; Provo, Utah; San Antonio, Texas; San Diego, California; San Francisco, California; Salt Lake City, Utah; Seattle, Washington; and The Triangle, North Carolina.. Even in Fiber-connected cities, not every geographic area within the city will have access to the 1 Gig service.

“With increasingly connected homes and ever-improving technologies, speed is more important than any time in our history—and becoming more important every day. And with our fiber networks, we’re uniquely positioned to deliver it,” Google said.  “You won’t have any data caps to interrupt even the most impressive binge-watching session. And with the power of a gig, you’re able to use all your connected devices at home at the same time,” the company added.

If Google Fiber sounds like the internet plan for you, please visit the Google units official website to check if your location is supported.

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

In its seven-year lifespan, Google Fiber has never had a single price increase.  Its straightforward, month-to-month (cancel any time) payment model has always been more attractive than what many competing services offer (many require a one year contract with huge cancellation fee).

Google Fiber’s ambitions are a lot more modest than they used to be. So the news applies to a pretty small percentage of Americans. Fiber scaled back its roll-outs in the mid-2000’s and had to pull out of Louisville, Kentucky earlier this year, following problems with its cable installations beneath the city’s roads.  Google put the brakes on most of its expansion efforts, like in the author’s home town – Santa Clara, CA.  Apparently, there were just too many hurdles, including the cost of expanding into certain areas, getting permission from the city councils, disputes over access to utility poles, and other challenges.

Altice Portugal Interview: 10Gbps services to build the ultra-connected future

Interview of Alexandre Fonseca, CEO of Altice Portugal by Chris Kelly of Total Telecom

Portugal is one of the most ambitious nations in Europe with regards to FTTH penetration targets. How are you progressing with this and what challenges are you facing?

Due to the work developed by Altice Portugal in the last years, Portugal is today an international case study with proven experience in several countries, such as USA, France, Russia, New Zealand, India, the UK or Brazil, regarding FTTH projects. Altice Portugal presents one of the best and largest next generation network infrastructures, reaching 4.8 million of households in Optical Fiber, moving closer to the 2020 target of 5.3 million. This brings Portugal as one of the first countries in Europe to reach nearly 100% of the population. We deployed FTTH throughout the country, both in urban and rural areas, boosting the economic development and digital inclusion.

Despite the significant investment performed, it is important to underline that Portugal still awaits for a 5G Roadmap, regarding the availability of frequencies and licenses in order to launch 5G commercial networks. The country needs a clear strategy and vision for 5G, to continue to take the lead, as in previous technology generations of telecommunications.

Does Europe need to agree a single unified switch off date for its existing copper networks?

The optical fiber infrastructure is more robust and more reliable in technological terms, being more immune to adverse weather conditions, thefts or vandalism, with a much lower failure rate than the copper networks and, consequently having better operational responsiveness, besides the significantly better performance it brings to Services.

The replacement of copper by optical fiber, being a natural evolution both for technological and business reasons, depends on each country´s dynamics, not being determinant the existence of a single date for this to happen. However, this change is essential for Portugal to remain at the forefront of Europe and is also sustained by the fact that copper networks are obsolete and unable to support new innovative services. Optical fiber is undoubtedly the technology that makes it possible to offer a set of new future proof services and features that copper no longer supports. Altice Portugal has started a pilot project in parishes of six Portuguese municipalities that were 100% covered by fiber. The project contributes to digital inclusion growth, broadening access to advanced services, promoting economic development and modernization and of course, copper decommissioning.

 

With the emergence of new technologies, what scope is there for delivering 10Gbps services?

10Gbps services will help us build the ultra-connected future we all require. The predicted increase in number of devices and data volumes requires intelligent networks with a new level of speed and capacity. Homes with 50-100 connected devices will drive unprecedented demand. Now, life-changing technologies for connected health, augmented and virtual reality, will deliver incredible experiences and require significant speed, low latency and high capacity. 10Gbs services are becoming more crucial for the enterprise market, namely for data center access, data center interconnection and trunk circuits to collect high bandwidth traffic from data, video & voice under virtual private networks.

The launch of new technologies is not a goal in itself – what really matters is the experience provided by services and the added value for customers. That’s the world we are building, one in which everything is connected everywhere.

 

What role will fibre play in underpinning 5G mobile network rollout in Portugal?

5G technology is not simply about faster internet connections, it will bring huge changes in network architecture and services. It will enable a step change of ultrafast broadband connections, boosted by low latency, ultra-reliable communications, massive machine-type communications and slicing capabilities. The major characteristics introduced by 5G can be summarized in the Throughput, Latency and Density of the connections.

Fibre optics will be a key enabler of 5G, especially as a backhauling technology, once it provides the extremely high speeds, capacity and low latency required to connect each 5G station. FTTH rollout is a key differentiator for providing nationwide 5G coverage and Altice Portugal is ready and prepared for 5G rollout, with over 95% of its mobile stations already connected through fiber. Besides the FTTH deployment, Altice Portugal performed the first 5G live demonstration in a commercial network environment with pre-commercial terminals in July 2018 and the first live television broadcast in Portugal using the 5G network in real environment in June 2019.

How much of a game changer is 5G going to be in regard to IoT uptake?

5G will have a fundamental role boosting the era of smart connectivity, capable of taking advantage of unreachable response times with today’s technologies, to grant new scenarios of digital interactivity on multiple devices. 5G will reinforce applications for B2B, B2C and B2B2C markets, especially in areas as IoT, or IIoT, industrial automation and critical services, especially in Healthcare, Smart Grids, Smart cities, Industry 4.0 or Autonomous Vehicles, being a relevant factor in the development of the economy of each country and the world in general.

Altice Portugal has been exploring, for a long time, the opportunities related to IoT. In 2018 we opened the Golabs.IoT, a live technology Lab that generates synergies between developers, universities, startups and industry players.

Altice Labs, our R&D unit, also has projects in 5G and IoT landscape, with several national and international institutions, including Portuguese municipalities, such as the city of Aveiro, with 5G being available for the development of early adoption services for cities or citizens, on an open community enviroment.

What predictions do you have for the industry over the next 12-18 months?

Companies and businesses are undergoing a very important digital transformation process…the telecommunications sector is amongst the ones suffering the most, but also well positioned to have a leading role on this transformation.

We will surely see a transition´s process from automation to true digitalization. Digitalization has accelerated information production and distribution, innovation and process disruption, together with the integration of the physical and virtual worlds and the use of real time data. All this has a huge impact on organizational structures, business models, logistics operations and products and services themselves.

But this is not just a business-level transformation. This represents a social transformation, with new ways for people to relate themselves, to learn, to work and providing all equal access to technologies.

The process of digital transformation and technological development requires us to always innovate and our effort and commitment must be dedicated to always bring more and better services to the Portuguese.

We believe that the Smart Living concept will bring forward a set of new and combined technologies, for personal and business usage that will improve our live, generate the opportunity to save time and therefore improving our work life balance. Technology will continue to improve people’s life’s and business productivity, providing quality time to individuals, families and communities, turning content and experience the most relevant killers Apps in this new technology generation.

Nokia successful field trial of single-carrier, 50.8 terabit-per-second on Etisalat’s WDM fiber optic network

Nokia and Etisalat (UAE) report the completion of a multi-terabit-per-second, single-carrier data transmission over an operator-deployed fiber network in a field trial.  Nokia said in a press release that a terabit-per-second is enough bandwidth to download the entire “Game of Thrones” video series in HD in under two seconds.

Using Etisalat’s wavelength division multiplexing network, the companies were able to reach a transmission speed of 50.8 terabits per second over 93 kilometers of optical fiber.

Nokia said the trial successfully transmitted a record 50.8 terabits per second using multiple wavelengths, each with a net information rate of 1.3 terabits per second, over a 93-kilometer fiber route of Etisalat’s wavelength division multiplexing (WDM) network.

The Nokia field trial showed that Etisalat’s existing network could support the higher optical wavelength bit rates that will be required to support high-bandwidth services such as 5G extreme mobile broadband, fiber-to-the-home (FTTH) and data center interconnect (DCI) cloud services.

Here are the key points:

  • Trial is the world’s first terabit-per-second, single-carrier data transmission over an operator deployed fiber network.
  • New transmission capacity record comes as Etisalat invests in core network infrastructure in anticipation of a new generation of high-bandwidth services.
  • Results move Nokia Bell Labs’ experimental lab records of terabit-per-second single-carrier transmission to a deployed operator network.

In addition to the speeds, higher bit rates per wavelength enable power and space savings, improved network simplicity, as well as increased spectral efficiency and capacity. It also enables reduced cost per bit compared to optical networks composed of lower rate channels, according to Nokia.

Using a single optical carrier operating at 100 Gigabaud, the terabit wavelengths tapped into Nokia Bell Labs’ probabilistic constellation shaping (PCS) to intelligently shape the signal to achieve maximum capacity for the specific fiber route. Nokia said its Photonic Service Engine 3 was the first coherent digital signal processor to implement PCS.

Esmaeel Alhammadi, Senior Vice President, Network Development at Etisalat, said:

“We are pleased to have partnered with Nokia Bell Labs to demonstrate that our optical network is capable of transporting a terabit per second over a single wavelength, and a total per-fibre capacity of over 50 terabits-per-second.  Increasing network capacity helps us to provide bandwidth-hungry services such as 5G extreme mobile broadband, fibre-to-the-home and DCI for enterprises.”

Sam Bucci, Head of Optical Networking at Nokia, said:

“The introduction of 5G will require a network that can support dramatic increases in bandwidth in a dynamic fashion. This ground-breaking trial with Etisalat is testimony to Nokia’s commitment to continue to invest in coherent and optical component technologies required to meet the 5G networking challenge at the lowest total cost of ownership for our customers.”

Nokia has a long history of advancing the frontiers of optical transmission. It was the first to demonstrate single-carrier 100G transmission in a deployed production network in 2007, and the first to commercialize single-carrier 100G and 200G wavelengths in 2010 and 2013, respectively. More recently, the Nokia Bell Labs optical research team published the world’s first terabit-per-second transmission lab trials in 2015 and 2017.  By extending these records to a deployed operator network, Nokia Bell Labs is bringing the age of terabit wavelength networks a big step closer to reality.

Details of the Nokia trial with Etisalat were published in a post-deadline co-authored paper at the European Conference on Optical Communication (ECOC), held last week in Dublin, Ireland:

Verizon CEO: 5G will require fiber optic expansion, mobile edge computing and continue to use mmWave spectrum

Verizon 5G Overview:

Verizon’s 5G network strategy is centered on three deliverables with fiber optics for backhaul playing a huge role in all of them:

  1.  5G mobile for businesses and consumers,
  2.  5G home broadband (see Note 1. below) —delivering home internet over the air—and
  3.  Mobile edge computing, which is essentially miniature data centers distributed throughout the network so they’re closer to the 5G endpoints.

The company’s CEO Hans Vestberg said that a total of 30 5G mobile cities will be launched by Verizon this year. He also plans to restart Verizon’s fixed wireless 5G Home service [1] later this year. 5G Home currently is in four U.S. markets.

Note 1.  There is no standard for 5G fixed wireless and none is even being worked on.  It is not an IMT 2020 use case within ITU.

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

Fiber and Mobile Edge Computing:

The U.S.’s #1 wireless carrier by subscribers will continue to install fiber at a rate of 1,400 miles per month in support of its 5G network builds for between two and three years.  Verizon will begin to provide mobile edge computing [aka Multi-access edge computing (MEC)] during the upcoming quarter, Vestberg said at a Goldman Sachs Communacopia investor conference on Thursday, September 19th.  Verizon fiber deployments are critical to supporting a mixture of services, Vestberg said.

As part of its Fiber One project, two years ago Verizon signed a $1.1 billion, three-year fiber and hardware purchase agreement with Corning to build a next-generation fiber platform to support 4G LTE, 5G, and gigabit backhaul for 5G networks and fiber-to-the premise deployments to residential and business customers. Also in 2017, Verizon also announced a $300 million fiber deal with Prsymian Group to provide additional fiber for its wireline and wireless services.

“The whole Intelligent Edge Network was basically all of the way from the data center to the access point we have one unique network for redundancy. And then, of course, in between fiber to the access point and then you decide if its 5G, 4G, or fiber to the home or fiber to curb, or fiber to the enterprise,” Vestberg said. “In that, the fiber deployment for us was extremely important.”

“One part of the whole intelligent edge network was that . . . all the way from the data center to the access point you have one unique network with a lot of redundancy and, in between, a lot of fiber to the access point and then you decide if it’s 3G, 5G, 4G or fiber to the home or fiber to the curb or fiber to the enterprise,” he explained.

Vestberg said: “You have one unique network with a lot of redundancy and, in between, a lot of fiber to the access point,” he said of edge computing, which has become a priority for many wireless and wireline network operators.

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

mmWave for 5G:

Verizon will continue to deploy millimeter wave (mmWave) for its 5G network for the foreseeable future, Vestberg told the investor conference audience.  High frequency band mmWave has great download speeds but its range is very limited, which requires many more small cells.

“Maybe you have 50 to 70 megabits per second on a 4G network today, when you get 1 gig [on 5G] it’s a totally different experience and what you can do with it,” Vestberg said. “What we saw in the 4G era was enormous innovation coming with that [greater] coverage and that speed [over 3G]. It’s going to be the same with 5G for sure,” he added.

“Now we have 2 gigs [gigabits per second] on the phones,” Vestberg said. The range, however, can veer from 2,000 feet to 500 feet and the network can’t deliver flashy streaming videos — or, in fact, any kind of service — indoors.  Verizon is the only US carrier solely dedicated to the highband (28GHz) approach to 5G for now. AT&T and T-Mobile plan to launch low and mid band 5G networks next year, along with limited mmWave deployments. Sprint has mid band 5G launched so far.

“We can launch nationwide with millimeter wave,” the Verizon CEO insisted.  “Any spectrum will have 5G in the future,” Vestberg noted. Verizon will also offer dynamic spectrum sharing (DSS) in the future. DSS will allow operators to share spectrum instantaneously and simultaneously between 4G and 5G networks. But not for mmWave, since that doesn’t share spectrum with any 4G networks.

Vestberg said Verizon has all the spectrum it needs now to do a nationwide network on mmWave, and that adding more antennas in a given area or making software adjustments are also options for increasing capacity on existing spectrum bands.

Vestberg insisted that the mmWave-based service will be “self-install.” This would be more economical than the “white glove” — a.k.a. professional — installation model that 5G Home started with in October 2018.

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

Verizon’s mobile network:

A growing percentage of Verizon’s mobile subscribers are on unlimited data plans, with about half today.  “This is a way for us to continue to see that our customers have a great journey from metered plan to Unlimited (data) plans and then they can move up…to 5G,” Vestberg said.

“We think that we are best equipped to leverage the best network and continue to partner with [media companies] rather than us managing it.  Others might have better qualities for doing that but we don’t, Vestberg said.
