I’ll send a separate note to Steve Diamond, who is coordinating it.

I am looking forward to following up with you regarding the virtual networks effort.

There is also RTF research group on virtual networks  called:
Virtual Networks Research Group (VNRG).

From Gary Mazzaferro:

I enjoyed your comments about the need for cloud standard initiatives. I”m of the same opinion and have slowly been moving towards a more collaborative initiative. The largest challenge is balancing time and funding. I have little time because of the lack of funding for the project. 🙂   I do have an idea how to make it work and gain participation by the user community

From InformationWeek:

The bigger message was that there is still much work to do in this area. With a ton of standards bodies emerging today, and vendors coming to market with their own unique APIs, it’s becoming difficult to have one voice.

If cloud is going to gain any kind of traction, let alone achieve the nirvana of the Inter-cloud, then we must have some level of standards in place to make it happen. As we’ve seen historically, not having standards in place has created challenges around interoperability, as well as vendor lock-in. The value proposition around cloud computing is negated if interoperability is not possible. It’s as simple as that. No ifs, ands, or buts.

http://www.informationweek.com/cloud-computing/blog/archives/2010/03/4_thoughts_from.html

NIST, a federal agency that has been instrumental in defining cloud computing, will take on an additional role as a central publisher of cloud use cases accompanied by a recommended reference technology implementation. “But the airing of strong use cases where a technology set is deemed suitable for a particular problem could lead to a specification for a standard, a NIST representative at the Cloud Connect show in Santa Clara, Calif., said Wednesday in an interview.”

Here is a link to view what others have written about the Cloud Connect Conference I attended in Santa Clara, CA:

http://www.cloudconnectevent.com/2010/in-the-news.php.

At the March 10th IDC 2010 Directions Conference in Santa Clara, IDC analysts Amy Lind and Carrie MacGillivray predicted a 32% compound annual growth rate (CAGR) for global mobile broadband connections, which were projected fo reach over 350M by 2013.  [We wonder if those include M2M connections, which are potentially much larger than human held device connections].

More significantly, LTE was predicted to have a CAGR of 471%, with 2012 (and later for some countries) as the critical inflection point for LTE mass adoption.  The technology was said to: offer improved capacity, full mobility (vs “mobile” WiMAX portability), be Initially oriented toward PCs  with pricing In flux as operators continue to rethink their business models.  

By 2013, IDC predicts:

• Mobile broadband will be ubiquitous and the defacto way of communicating
• Business models will be focused on revenues per subscriber or device   
• Global mobile services spending will surpass $975 billion
• Iconic 4G devices will be critical to success

The two IDC analysts offered their essential guidance to session attendees:

• Wireless carriers should place emphasis on data services, which are essential for revenue growth.  
• Detailed market segmentation is required to focus devices (and apps) on relevant audiences.  To achieve this objective, IDC believes that wireless network operators will deepen partnerships with device and application vendors (AT&T and Clearwire are already doing this now).
• Integration key to staving off wireless displacement and driving mobile broadband adoption

In a separate presentation, IDC Research Manager Godfrey Chua was very optimistic about LTE.  This author was stunned to hear Mr. Chua predict that LTE infrastructure equipment sales would overtake all WiMAX infrastructure sales by 4G 2011!  That’s less than 18 months from now!   According to Mr. Chua, both AT&T and VZW are looking to LTE to effectively deliver high quality mobile broadband service at the lowest cost per bit possible (through the more cost efficient OFDM based modulation and multi-carrier transport).  He sees 2012-2013 as the LTE market inflection point, which is consistent with the opinion of other IDC Analysts.  Why have all the major global cellular operators made such an early committment to LTE?  Here are a few reasons given: 

• To deliver high quality mobile broadband at the lowest cost per bit
• To relieve 3G capacity pressure by migrating laptop users to LTE
• To create a more robust platform for applications and services –that lead to new business models and therefore revenue streams         

Godfrey next compared the rationale and position of LTE (vs WiMAX):

• To address capacity pressure in 3G networks (vs WiMAX to address underserved broadband connectivity demand)
• Full mobility is the value proposition (vs WiMAX portablity of netbooks/notebook access)
• Geared towards developed markets (vs WiMAX orientation toward emerging markets)
• Relevance to emerging markets not until 2015 (vs WiMAX being always relevent to emerging markets)                                 

2010 will be a critical year for LTE network equipment companies as they all seek to build momentum. in the forthcoming global market.  Mr. Chua sees Ericsson and Huawei as early leaders in providing LTE gear.  He says that Alcatel – Lucent’s Verizon Wireless win is key, but now they must convert trials into contracts.  Meanwhile, Nokia Siemens Networks is  looking to maintain relevance in LTE.  The competitive pressure will surely intensify as other players –Motorola, ZTE, NEC and Fujitsu –seek to up the competitive ante. 

In closing, Godfrey offered the following essential guidance: 

• Realization of the long-held vision for the network is near
• Mobile data traffic will continue to explode
• Network transformation is critical, it is key to remaining competitive
• Green efforts will persist, it goes hand in hand with the transformation process
• Vendor positions will continue to shift

Some additional predictions from IDC Analysts:

John Gantz, Chief Research Analyst: 

-By the end of 2010, there will be 1B mobile Internet users and 500K mobile phone apps.   1.2 billion mobile
phones will be sold; 220 million smart phones.  630 million laptops in place; 80 million netbooks. 

–There will be many intellgent devices communicating with machines/computers.  M3M is a potential high growth area.

-Complexity will increase 10X in the next 10 years

-By 2020, there will be 31B connected devices, 2.6 billion phones, 25M apps, 450B interactions per day, 1.3T tags/sensors

Rick Nicholson, Vice President, IDC Energy Insights:

Disclaimer: Unlike many “would be journalists” that are either always negative on WiMAX, or are perennial Pollyannas that produce an endless stream of recycled “happy talk,” this author tries to be balanced and objective of WiMAX in general and the WiMAX events covered in particular. We have been covering WiMAX for over 6 years now, with more than 200 published articles on that technology.  This author has no business relationships with Clearwire or any other WiMAX related company or entity. Please read on……

 Introduction

Clearwire briefed potential application developers at a well attended CLEAR Developer workshop in Santa Clara, CA on March 2, 2010. The key sessions were Upcoming 4G WiMAX APIs and Tools, The 4G WiMAX Business Opportunity for Developers, and the wrap up session revealing where Clearwire is now and where they’re going. You can find all the Sessions and speakers here.

We will skip the discussion of WiMAX APIs and Tools, which was already covered in detail at the Feb 10th IEEE ComSoc SCV meeting (you can access the slides at:  http://www.ewh.ieee.org/r6/scv/comsoc/Talk_021010_CLEARDeveloperOverview.pdf).

Nonetheless, we noticed a lot of keen interest amongst developers who were accessing Clearwire’s Silicon Valley 4G Innovation Network using 4G USB sticks attached to their notebook PCs. It seems indoor coveraged worked fine in the Santa Clara Convention Center, where the workshop was held.

However, we were quite disappointed that neither Comcast or TW Cable had any new services to tell us about, despite the video content and managed networks they each own. More about this later in the article.

The Wholesale Opportunity

Clearwire (CLRW) was said to own more licensed spectrum in major cities than any other wireless network operator. Their “4G”+ network, known as CLEAR, is now covering more than 34 million points of presence (POPs) as of 4Q-2009. It’s also commercially available in 28 different U.S. cities including Seattle, Honolulu and Maui. CLRW plans to build out their mobile WiMAX network to reach 120 million POPs by end of 2010. They’ll have launched CLEAR service in most major U.S. cities by the end of the year including New York, San Francisco, Boston, Houston, Kansas City and Washington, DC. By this time next year, the CLEAR network will stretch from coast to coast and cover all the major U.S. cities.

In addition to selling “4G” fixed and mobile wireless broadband Internet access, Clearwire has MVNO (wholesale) agreeements with three of their large investors –Sprint, Comcast, TW Cable– who are reselling the service under their respective brand names. These partners were said to have a combined customer base of approximately 75M subscribers and their well known brand names would help the combined entities achieve a critical mass of customers much quicker than if only Clearwire was selling WiMAX services. Wholesale resellers will also drive WiMAX ecosystem development and investment, according to Randy Dunbar, Vice President, Wholesale Marketing & Strategy, Clearwire.

Mr. Dunbar told the audience that Clearwire will be signing up more MVNO resellers in the near future. These may include companies involved in: consumer electronics, retailers, CLECs, pre-paid/targeted market segments, smart grid and M2M (least understood by Clearwire, but with tremendous potential). The new resellers will help Mobile WiMAX deployment in diverse market segments such as: mobile consumer, home entertainment, power Internet user, SOHO, small business, large enterprise, vertical business’, road warriors (business travellers).

Currently, there is only one known hand held device available for CLEAR -the Samsung Modi. “4G” access is currently obtained using an external USB modem or “dongle,” embedded WiMAX in a PC, or a “personal” WiFi hotspot (many of which require an external USB dongle to access the WiMAX network). But Mr. Dunbar said that a “range of connected devices” are coming for CLEAR. These devices include: smart phones, STBs, DVR, mobile modems, MIDs, Consumer Electronics gadgets (such as portable media players). Randy hit my hot button when he stated that programmed video and time/place shifted video would be delivered via the 4G CLEAR network (see next section of this article).

+ IEEE 802.16e-2005 based Mobile WiMAX (being deployed by Clearwire and partners) is actually 3G according to the ITU-R;   IEEE 802.16m will be the 4G version of mobile WiMAX, but Clearwire has not committed to that yet.

Cable (MSO) MVNOs reselling Clearwire’s mobile WiMAX network

Comcast, the largest MSO in the U.S., resells the CLEAR network as “Hi Speed to Go.” It’s branded mobile WiMAX service is available in Portland, Atlanta, Chicago, Philadelphia, Seattle/Bellingham area. Katie Graham, Director, Wireless Business Development said there were two ways mobile WiMAX could be purchased from Comcast:

• Fast pack: Cable Internet (home access) bundled with High Speed to Go
• Bolt on: 4G mobile WiMAX only or 3G/4G (using Sprint’s EVDO network for 3G)

A free WiFi router is included with a Hi Speed to Go subscription. More details on the Comcast mobile WiMAX service is at: http://www.comcast.com/highspeed2Go/#/highspeed2go

TW Cable has been completely spun off from Time Warner as a separate company (which means they don’t own any video content). Their CEO had recently stated that high speed Internet was replacing video as the firm’s core product. TW Cable currently serves 14.6M customers in 28 states. They claim to be the third largest broadband ISP in the U.S. with 9M subscribers. Brian Coughlin, Manager, Wireless Platforms for TW Cable told the audience that data oriented wireless products and services would be first priority for the company, with voice and mobile phones later. Brian stated that “Digtial media and service must be adaptable” and that an ecosystem would be required for this. I took this to mean that digital media and video services needed to be able to adapt to broadband access via mobile WiMAX, but I was wrong (see below for the reason).

The two MSO behemoths were asked by this author why they haven’t offered any premium video services or VoD over mobile WiMAX and they appeared to be stumped. Some of the explanations given were:

“The technology is ahead of the business models.”  Clearwire

“The industry hasn’t figured out how to monetize the video applications.”  TW Cable and Clearwire

“It’s definitely on our radar screen, but we don’t have anything we can announce at this time.”  TW Cable

“Digital content rights are based on a given device, not on a service.”  Comcast

We were preplexed by these statements. In particular, we do not understand why Comcast can offer On Demand Digital Video* over their managed network and cable Internet service, but not over mobile WiMAX.

* For details on Comcast On Demand On line service please visit:

http://www.comcast.net/on-demand-online/

Kittar Nagesh, Service Provider Marketing Manager at Cisco also participated in this panel. He made three statements I thought were very important:

• “Video will be 66% of mobile video traffic by 2013.”
• “The spectrum Clearwire owns is remarkably important. It’s important to make use of the spectrum (a wireless network operator) you have. It doesn’t matter if it’s used for WiMAX or LTE.”
• “M2M applications will be phenomenally important. It will be an inflection point (for the broadband wireless industry). Innovation will explode in an unbounded fashion.”

Shortly after this event, Cisco withdrew from the WiMAX RAN equipment market. They had been selling WiMAX base stations (from the Navini acquisitiion), but they now think there are better opportunities in the mobile packet core via their acquisition of Starent Networks).

Wrap Up Session: Clearwire now and in the near future

Dow Draper, Clearwire Vice President for Product Development and Innovation, told the audience that the average Clearwire customer is using 7G bytes of downloaded data per month — a number that Clearwire only expects to increase over time. That compares with an average 3G data card download of 1.4G bytes/month and an iPhone 3G average download of 200 M bytes/month.

Mr. Draper also said that the S.F. Bay Area can expect commercial WiMAX service by “late 2010,” and that “multiple smart phones” would be running on the Clearwire network before year’s end. Dow also hinted at other upcoming devices for CLEAR: MIDs, Portable Media Players (PMPs), tablets and embedded devices. He distinguished between category 1 devices which are tested and sold by Clearwire and category 2 devices which are sold through channels (and presumably retail stores).

“Clearwire will support multiple Operating Systems, especially Android,” said Mr. Draper. In summing up he said that thrid party developers, differentated devices, services, and applications are all critical in attracting customers for Clearwire and their MVNO resellers. While we completely agree with that statement, we think that the devices need to come to market very quickly (they’ve been promised for quite some time by Intel but haven’t materialized). But even more important are the differentiated services, such as video- either for entertainment, education, or surveillance.

IEEE ComSoc SCV February 10^th, 2010 Meeting Report

“Developer Opportunities with CLEAR WiMAX 4G”

This very informative and exciting meeting drew a large audience of over 85 attendees. Those present heard directly from Clearwire’s about their Silicon Valley Innovation Network (based on IEEE 801.16e-2005/Mobile WiMAX) and tools that are being made available for CLEAR 4G applications developers. Representing Clearwire were Allen Flanagan, Manager, Silicon Valley Innovation Network, and David Rees, Manager, Developer and Partner Enablement. The event featured excellent presentation by both speakers followed by Q&A as well as a panel discussion where meeting attendees were able to ask questions not already covered in the talks. The presentations and subsequent Q&A were moderated by Sameer Herlekar, ComSoc SCV Technical Activities Director, while the panel discussion was chaired by Alan Weissberger, ComSoc SCV Chairman.

Presentation Highlights:

David Rees, in his talk on “Application Developer Enablement,” first provided some background on Clearwire and its network.  Clearwire was said to be a broadband wireless network provider currently operating in 25 markets and reaching 30 million people with the potential to cover 80 markets and reaching 120 million people by the end of 2010. (Note that “people” here refers to the total populace in these markets, not the actual number of Clearwire customers.) Dave told us that Clearwire’s “4G” WiMax network (following the IEEE 802.16e-2005 standard) operates nationwide in the 2.5 GHz spectral band with an average of 150 MHz spectrum available per market. The principal funding sources for Clearwire’s 4G network deployment plans include Sprint, Comcast, Intel, Time Warner, Google and Bright House Networks. In fact, Clearwire received over $3.2 billion in funding and resources from these sources in 2008 alone. Additionally, the talk elaborated on the benefits of the WiMax-based 4G network over the contemporary 3G networks based on EV-DO and HSPA in terms of higher data rates and spectrum capacities, stronger device mobility support, and amenability for low-cost deployment via an all-IP network. Specifically, based on results from drive-testing their network in Portland, OR over a 17-mile distance at an average speed of 35mph and a top speed of 55mph, Clearwire claims that their network’s performance is an order of magnitude superior to the 3G networks over the same route in terms of peak and mean data rates as well as network latency. Clearwire’s teams attained a peak data rate of 19 Mbps, a mean data rate of 6.5 Mbps and a mean latency of 83 ms during the drive testing.

Mr. Rees then shifted to Clearwire’s plans for Application Developer Enablement, i.e., the platform which enables (or, to be precise, which Clearwire seeks to enable) application developers and OEMs devise applications and services which leverage the enhanced speed and capacities of the 4G network. David Rees then explained Clearwire’s philosophy of an “open network for open devices”, where any WiMax-enabled device including those based in MIDs, camcorders, netbooks and smartphones will be able to access the 4G WiMax network. In fact, the devices do not even have to be necessarily provided by the carriers. However, they will need to be certified by the WiMax forum before they can be considered admissible on Clearwire’s 4G network.

The presentation then explained how, in order to support the “open network for open devices” paradigm and the mobile internet applications operating thereupon, appropriate application program interfaces (APIs) need to be made available to developers and service providers. These APIs need to be able to access the mobile device’s location information as well as be aware of the network itself, thereby providing a superior quality of experience to the end-user. Clearwire seeks to provide location information via APIs that employ a client/server service whereby applications can determine their own locations (“where am I?”), a server/server service which enables geo-fencing or tracking (“where are they?”), enabling location in browsers themselves including Chrome, Firefox and IE, and also by working with existing location providers to use WiMax for reporting location information. For example, a lightweight JSON/HTTP service allows client applications including browsers to query their locations and obtain their latitude/longitude information from the server. Clearwire is also working on adding direct support for Google Gears, Firefox and other browsers. Similarly, the server/server service employs the device’s IP address or MAC address to determine the device’s location. Network-awareness will be provided via Session Information and includes enhanced location awareness via triangulation, radio-signal quality information, as well as diagnostics collection and reporting such as round-trip time to each neighbor (future enhancement) and neighboring sector information (also a future enhancement). The session information is sought to be provided by a single, or common API, the so-called CAPI, which Clearwire is currently standardizing and promoting. As a matter of fact, CAPI 1.2.1 has already been implemented on a variety of chipsets including Intel’s WiMax-enabled laptops. Moreover, CAPI 2.0, which is currently being standardized, will (when available commercially) include such features as neighboring sector information, handoff notification and a list of applications requesting a particular quality of service (QoS).

Suggesting that Clearwire views mobile video as a major application for the 4G network-enabled mobile internet, the talk elaborated on Clearwire’s efforts to ensure a high-quality end-user experience by supporting in-network video optimization as well as session information provision to video clients, video servers and video service providers to help them optimize their transmission/reception performances.

The final part of the Developer Enablement portion of the presentation focused on QoS and its current status vis-à-vis Clearwire’s 4G network deployments. The talk explained that traffic streams such as video are specified to have a particular service-level in terms of throughput, latency (network delay) and jitter (delay variation). The network then identifies these streams and attempts to provide the desired service-level to each stream with a goal of minimizing the likelihood of network congestion while concurrently supporting different service-levels. At this time, while QoS has been implemented in Clearwire’s network, it will be offered to users only after Clearwire concludes its ongoing open-internet NPRM talks with the FCC and it’s (Clearwire’s) partners on when QoS-on-demand should be formally deployed. Additionally, Clearwire is yet to finalize its strategy with respect to load balancing (balancing QoS demands from a plurality of end-users), as well as network management once full QoS-on-demand becomes available, possibly in the third quarter of this year.

The Developer Resources section of the talk was presented by Allen Flanagan, where the 4G WiMax Innovation Network, also known as CLEAR was explained in detail. According to the presentation, CLEAR is a pre-commercial network deployed in parts of Silicon Valley including Palo Alto and Menlo Park, Mountain View and Santa Clara for testing mobile device-based applications. Registered service, application and content developers may make use of this service for free for the duration of the program. Noting that the CLEAR program encourages app developers to create applications which take advantage of the mobility aspect of the device, the talk pointed out that the Innovation Network is, however, not a testbed for hardware nor is it intended for end-users. When invited to suggest an example app for the 4G Innovators Network, Allen Flanagan outlined an application for public safety teams which could perform voice recognition and possibly translation. Such an app could be very useful for disaster-hit areas where local first-responders need to communicate with emergency workers who may not speak the native language. The talk concluded with an invitation to the audience members to receive free passes to the 4G WiMax Developer Workshop to be held in Santa Clara Convention Center on March 2^nd of this year.

Panel Session:

The panel session, moderated by Alan Weissberger, addressed a number of issues which were raised even during the Q&A sessions following the speaker presentations. Both the Clearwire reps provided a wide-range of information on device and app certification, locations (stores) where the apps may be obtained, as well as the all-important question of QoS. During the panel discussion, audience members came to learn that:

There will be no special app store for CLEAR-developed applications. Clearwire welcomes apps purchased through stores belonging to their partners like Intel, Google, Apple and Palm.

Clearwire certifies devices approved by the WiMax forum and will certify only those apps which are provided by Clearwire; any other developed apps will not be certified by them.

Clearwire’s handheld WiMax device will become available later this year.

Network usage and available capacity will be monitored over time and adjustment of capacity will be made based on backhaul traffic statistics. While real-time capacity adjustments are not possible, Clearwire will leverage the 150 MHz of available spectrum to help meet any projected increase in user demand for capacity.

When pressed on whether Clearwire’s business model takes into account a point of network failure due to conflicting user demands for QoS, or whether Clearwire can guarantee that a fixed QoS will be supported by their network for a (statistical) percentage of communicating devices for a (statistical) fraction of the time, the Clearwire reps acknowledged that the QoS-on-demand issue is a major challenge to network planners and that they will relay the question to the their engineering teams as developer feedback.

When asked whether Clearwire’s future WiMAX enabled phone would use mobile VoIP or cellular voice, Clearwire’s Allen Flanagan understandably refused to answer as the product has not been officially announced. For speculation on what type of voice would be used on WiMAX handsets, please see:

http://viodi.com/2010/02/16/wimax-handsets-for-clear-vs-mobile-skype-over-vzw/

Analysis and Opinion:

The 4G WiMax network being deployed by Clearwire as a means to enable the mobile internet is certainly a very strong response to the tremendous attention being accorded to LTE in recent months. Additionally, the 4G Innovation Network program, a.k.a. CLEAR is a clever approach to attract app and content developers by providing them with free access to the WiMax network prior to any commercial deployments. That the CLEAR program targets Silicon Valley is not surprising either, given the vast number of hi-tech innovations which have been born in the valley. With regard to air interfaces, Clearwire’s drive-testing results showed that the OFDM-based WiMax combined with 150 MHz of available spectrum can achieve significant mobility support for major bandwidth-hungry applications such as mobile video (we note, however, that Clearwire’s drive-testing was undertaken at off-peak hours to minimize any loading effects).

Many industry experts predict that mobile video is the killer application for the true mobile internet. This viewpoint does not seem to have been lost on Clearwire, given their emphasis on supporting mobile video on their 4G network. In order to support apps which feature mobile video as well as other applications, Clearwire will provide APIs which support RF awareness, location awareness and network awareness. On the crucial issue of QoS, Clearwire has enabled QoS in it’s networks even though it is not yet available to end-users, pending talks between Clearwire, it’s partners and the FCC.

The solid attendance for this meeting and the number and variety of questions raised by the attendees points to great enthusiasm among potential app and content developers to leverage the promise of Clearwire’s 4G network.

Besides the current unavailability of QoS guarantees to support applications like mobile video, the network’s ability to support multiple bandwidth-hungry applications from multiple users (numbering in the hundreds of thousands in some markets) is still an open question which Clearwire’s engineering teams will no doubt be actively engaged in to answer. However, Clearwire has undertaken notable steps in its quest to acquire a lion’s share of the mobile internet network operator market including enticing potential app and content developers and service providers to develop a plethora of mobile apps via the CLEAR program. It is now up to developers to unleash their creativity and devise apps which are innovative, timely and which truly provide end-users with a superior quality of experience on their mobile devices. Simultaneously, Clearwire needs to live up to it’s promise of providing a network which supports high mobility and highly differentiated network services including QoS-on-demand for an overall customer base which potentially numbers in the millions.

This very informative, analyst – only panel discussion assessed the outlook for new and growing markets throughout the semiconductor industry. While several markets were covered, this summary will focus exclusively on the hot communications related markets and products. During the meeting, analysts from FBR Capital Markets, iSuppli, Databeans and Gartner shared their perspectives and predictions on what’s hot and why in several markets of interest to communications and network practitioners.

Craig Berger of FBR Capital Markets singled out smart phones and Set Top Boxes (STBs) as key semiconductor industry drivers. He said that China’s 3G infrastructure build-outs would have ripple effects across the industry and accelerate in late 2010. China is expected to spend over $60B in 3G related telecom equipment over the next two years. That’s certainly impressive! Craig opined that he expected India to "ramp up" 3G network production, but didn’t say when (India’s 3G licensed spectrum auctions have been postponed for well over one year now). In addition to 3G, Mr. Berger commented that wireless interfaces, such as WiFi, Bluetooth, and GPS, were propogating much more broadly into hand held devices that didn’t have much or any IC content previously.

FBR see a continued proliferation of smartphones, with +15% growth in 2009 and +25% expected in 2010. Handset chip content is actually increasing versus recent years. Other gadgets are expected to do well – Tablets, eBook readers, and MIDs. Chip makers that will benefit from this advanced wireless handheld trend are Qualcomm, Infineon, Broadcom, Marvell, Nvidia, Intel, and STMicro, according to Craig.

Distributed computing is another trend to watch. As broadband becomes faster and increasingly available, PCs do not need to have large amounts of on board storage, expensive operating systems and processors. Instead, they can be ‘dumb terminals‘ that just interface to Internet or cloud computing based servers.

Success is created when products are specifically designed to address a particular market niche. For example, Bluetooth is really 20 different sub-markets, depending on application and usage models. Broadcom has done paricularly well in these sub markets by offering a wide variety of components and combo chips that address the different requirements of the sub markets.

Introduction:

IEEE ComSoc SCV chapter meeting held on January 13, 2010 offered two hot topics of interest to attendees: the Mobile Packet Core (MPC) for 3G and 4G wireless networks and the outlook for Broadband Wireless Access (BWA) in India.  There were two presentations followed by a panel session which covered both the mobile packet core and BWA in India. This IEEE ComSoc SCV chapter meeting was chaired by Sameer Herlekar, ComSoc SCV Technical Activities Director. The meeting was well-attended, with the 72 people in attendance receiving the speakers’ presentations and panelists’ views with enthusiasm and often engaging the panelists in a lively debate on the issues involving MPC and BWA India.

Jay Iyer, Distinguished Engineer at Cisco Systems and Eric Andrews, VP of Product Management for WiChorus/Tellabs Company (who replaced Rehan Jalil, Senior Vice President, Mobile Internet, Tellabs) were the speakers who presented their respective companies’ perspectives on MPC and later participated in the panel discussion on the same subject. They were joined on the panel discussion by Arpit Joshipura, Vice-President, Strategy & Market Development, at Ericsson Silicon Valley who articulated Ericsson’s views on MPC as well as provided his views on BWA in India.

Presentation Highlights

 Presenting the first talk of the evening titled “The Mobile Internet Edge”, Jay Iyer elaborated on how intelligent networking built on an all-IP network foundation can help mobile broadband service providers monetize their investments while, at the same time, deliver a high quality of mobile experience to their subscribers. The user (subscribers’) experience will be marked by a rich suite of services including mobile video, enhanced voice and messaging, cloud-based services, other personalized services and featuring seamless interoperability over an array of devices. The talk also addressed how Cisco’s all-IP next generation network (NGN) architecture, named IP NGN 2.0 enables the ubiquity of these services. Noting that the mobile internet data traffic is projected to grow sixty-six fold by 2013-14, the presentation asserted that 64% of the mobile internet traffic by 2013 will be composed of mobile video, with speed of services and quality of service the key to user satisfaction and operator revenue generation. Additionally, the talk described the business models for new markets and services including collaboration cloud services and machine to machine (M2M) application services.

The second presentation of the evening, by Eric Andrews, was titled “Mobile Packet Core Trends” and focused on smart 4G packet cores for the mobile Internet. The talk observed that mobile operators the world-over are facing a severe shortfall of revenue following their introduction of mobile data services such as HSPA, in spite of actual mobile data traffic seeing an exponential increase over the same period. However, the talk also noted that the 103 million HSPA subscribers (as of Q4 2008) represented only 2% of the total mobile service subscribers. In order to meet this explosive mobile Internet data traffic growth, the mobile packet cores form a crucial network component within the new flat all-IP network architecture. Furthermore, the talk explained why smart 4G packet cores are well-positioned to not only handle the exponential volumes of data traffic (thereby enhancing the mobile subscribers’ quality of experience), but also enable network optimization and content monetization for the service operators’ benefit. Content and application awareness at the network, geographic and user levels, and a QoS guarantee enforced on identified content define the smart quality of these 4G packet cores. Additionally, the presentation elaborated on how a distributed core network architecture with internet offload at the network edge results in significant OPEX and CAPEX savings to the service operators while causing minimal operational impact on the network itself..

Panel Discussion

The three panelists concurred that the mobile Internet itself is the killer application for wireless communications, and that serious efforts need to be made towards extending the internet to help meet growing user demand for the mobile internet. Furthermore, the panelists asserted that the mobile packet core, in conjunction with either WiMax or LTE as the radio access technology is an ideal means to handle the exponentially-large volumes of data traffic expected from the mobile internet users. Eric Andrews noted that mobile users are demanding ever-increasing bandwidth for their mobile device applications and that the available bandwidth is never enough. This has been particularly true for the current state of the mobile internet, where the amount of bandwidth available to users has been far below the user’s expectations. A controversy erupted between a few of the audience members and the panelists on the question of whether off-portal services were threatening the traditional mobile operator business model and the walled-garden services. The audience members expressed their view that mobile operators have been restricting subscribers from accessing the services which they (subscribers) truly want while the panelists responded by stating their own case from the business angle.

The subject of BWA in India was then introduced by the panel moderator, Sameer Herlekar, who proffered his views on the topic, and was followed by each of the panelists who provided their own perspectives. Sameer Herlekar observed that the Indian government has initiated the BWA project in an effort to connect people in the rural areas of India to the Internet by leveraging wireless communication via WiMax as the transmission medium. This approach was mainly due to the inadequate reach of copper phone lines to the underdeveloped and remote parts of India. The three panelists observed that India is the single-largest WiMax market in the world and therefore offers mobile operators an invaluable business opportunity. However, according to Arpit Joshipura, the BWA in India will have to be deployed in the so-called metro (urban) areas first, and consolidation will need to take place among the operators before the rural markets can be tapped profitably. The panel and moderator also noted that bureaucratic hurdles are a serious impediment to the deployment of BWA in India, including the spectrum auction date which is still undecided despite a delay of over one year.

Analysis:

The opening of the airwaves to the Internet by mobile broadband is expected to spawn a host of new applications, user interfaces, services and technologies geared for mobile Internet subscribers. These applications and technologies promise mobile subscribers a whole new experience of the Internet by truly extending the Internet’s reach well beyond their desktops or laptops to their very person. Meanwhile, the mobile packet core (MPC) pledges to not only help the mobile operators monetize the tidal wave of mobile Internet data traffic expected to hit the backhaul networks, but also enable a brand-new user experience built on highly-personalized and innovative applications running on mobile devices. Companies like Cisco via their acquisition of Starent and Tellabs through their purchase of WiChorus are preparing for the aforementioned data traffic tidal wave, which has already begun. At the moment, MPC promises a win-win situation for both operators (from a business angle) and for subscribers for their Internet experience. If successful, the mobile Internet enabled by MPC and 4G radio architectures like LTE and WiMax could ultimately change the quality of our lives by providing true Internet access on-the-go. However, only time will tell if these prophecies eventually turn out to be as true as the operators are betting on, and as the mobile subscribers are looking forward to.

That the BWA market in India is potentially the single-largest WiMax market in the world is not in question. Please see this article by Alan J Weissberger for corroboration:  Study Predicts India to be Largest WiMAX market in Asia Pacific by 2013

http://www.wimax.com/commentary/blog/blog-2009/february/Study-Predicts-India-to-be-Largest-WiMAX-market-in-Asia-Pacific-by-2013-0209

Additionally, the Indian government’s belief that the far-flung areas of India can be connected to the Internet wirelessly is reasonable, if one is to consider the astounding success of the cellular phone services in India where 442 million subscribers currently enjoy the services and, on an average, 10 million new subscribers have been added per month over the last 2 years. However, the promise of monetizing the Indian BWA market will depend on when the BWA spectrum is auctioned and allocated to operators, which, as of the time of the writing of this article, was still not finalized. Furthermore, as Alan Weissberger has noted, the BWA deployment in India will feature WiMax for fixed broadband wireless access rather than true mobile WiMax, as Indian mobile operators plan to use 3G services for mobile broadband access. This result is rather surprising, as one would expect the WiMax supporters to have left no stone unturned to leverage the vast Indian mobile broadband access market potential and showcase mobile WiMax’s capabilities versus LTE.

IEEE ComSocSCV is extremely fortunate to have Clearwire reveal details of its "4G" Developer network at our Feb 10th meeting. Here are the preliminary details of what promises to be a very informative, exciting, and highly interactive panel session:

Mobile WiMAX (as provided by CLEAR, Sprint, Comcast, and Time Warner in the United States and by other carriers worldwide) and 4G represent an opportunity for a new generation of product and services that take advantage of true mobile broadband. CLEAR understands the true value of 4G WiMAX will be realized through these new product and services, and with this in mind is focused on enabling 3rd party services and devices for the CLEAR network.

What’s the next rev of CLEAR (which is currently based on IEEE 802.16e-2005 standard)?:

In recent interviews, Clearwire has backed off of its committment to a future version of Wimax (IEEE 802.16m AKA Wimax 2.0) and hinted it might consider deploying LTE as its true 4G technology.

In a discussion with Unstrung, Clearwire CTO John Saw said the company might begin testing equipment based on the pending IEEE 802.16m standard in 2011. The IEEE could approve the new 802.16m air interface specification this summer, but Mr. Saw says the company wouldn’t begin commercial deployment until 2012.

In a separate article, CNET’s Marguerite Reardon hints that Clearwire may eventually migrate to LTE- a competing technology that’s expected to be used by most of the world’s major wireless operators.

Clearwire may consider 4G alternatives to WiMax

This panel discussion, with brief presentations by the panelists followed by open discussion, offered fresh perspectives, 25 years after divestiture, on how it has worked out and what we need now.  An audience of 35-40 Globecom attendees including John Vig, the 2009 President of IEEE, joined the discussion.

The three panelists were Paul Kuehn, Chair of Communication Networks and Computer Engineering at the University of Stuttgart; John Cioffi, Hitachi America Professor Emeritus of Engineering at Stanford University (presently CEO/COB, ASSIA Inc.), and Daniel Wedemeyer, Chair of the School of Communications at the University of Hawaii.  Steve Weinstein, a past President of the IEEE Communications Society, served as moderator.  The panel had been organized by Jeremiah Hayes, Professor Emeritus at Concordia University, who was unfortunately unable to attend.  The History Session, stimulated by ComSoc’s communications history chair Mischa Schwartz, Professor Emeritus at Columbia University, was put together by Professor Jacob Baal-Schem of Tel Aviv University and Professor Hayes.

None of the panelists shed the usual tears for the loss of the Bell Labs of pre-divestiture days.  It was generally agreed that the pace of innovation had increased, not decreased, with the end of the period of Bell Labs dominance.  The term “innovation” itself has come more to mean products and applications rather than new technical knowledge.  Innovation in technology and applications has been taken up by a variety of structures including industrial-university collaboration, government-funded institutions and projects, and innovation by new small companies, many founded by entrepreneurs who spent time at the old Bell Labs.  In fact, the greatest loss from the disappearance of the old Bell Labs may be its role as “Bell Labs University”, a training ground for future entrepreneurs. 

There was discussion about the replacement for this training camp.  The panelists noted several developments, including regional government-industry projects and new university emphasis on entrepreneurial, environmental, and societal aspects as well as an interdisciplinary technical foundation.  Online access to vast bodies of knowledge and professional networking also support professional development    President Vig prompted the panelists to consider the role of  IEEE, which the panelists agreed had much to offer coming generations of innovators through enhanced distribution of technical information and building a broad technical community.

There was concern that some fundamental research aspects have been overlooked in the post-divestiture environment, with the fast outcome-oriented approach of today discouraging thorough study before products are put in the market, and sometimes neglecting more general applicability possibilities and security and privacy issues.  The panel hoped that both fast market launches and these more thoughtful considerations might somehow merge into a more holistic approach, with the European research funding programs a model, if not always an efficient one. Strong funding of basic research is desirable, not by a private or monopolistic organization as the Bell System used to be, but by "Center of Excellence" type organizations in universities or research institutes, in cooperation with corporate research. 

In summary, the Panel felt that the pre-divestiture Bell Labs was an important and necessary model for its time, but that the world had changed and there are new ways of creating a strong cadre of competent technical innovators.  As suggested above, these include government-industry-university collaboration and direct and indirect government funding of applied research and the transition of technical knowledge into product innovation.

Summary by Steve Weinstein
