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:

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.

Session Title: Developer Opportunities with CLEAR WiMAX 4G

Abstract:   David Rees and Allen Flanagan (see below for bio’s) will provide an overview of CLEAR’s network, nation-wide rollout, and device plans. They will provide details on CLEAR’s Innovation Network program and how Silicon Valley developers can get discounted aircards and free network access through 2010 to develop and test their 4G ideas. We will also walk through the available and planned platform and device services that CLEAR will be providing including location, network session information, connection management, activation, and provisioning. We will discuss some of the use cases of these services including proactive video optimization and location-enabled services.

Bio’s:

Allen has worked in the High Tech industry for over 15 years in a variety of roles from Enterprise Application development to Technology Channel Marketing. He holds a BS from the US Naval Academy and an MBA from the University of Texas.

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.

U.S. Vice President Joe Biden, speaking today in Dawsonville, Ga., said that $2 billion in grants and loans directed at broadband access buildouts will be dispersed over the next 75 days.  Biden’s initial announcement includes $182 million for 18 projects in 17 states awarded through programs administered by the departments of Commerce and Agriculture. Those projects have been matched by $46 million in private investment, the administration said.  

The grants announced today will fund both last-mile projects to connect remote homes in rural areas, and "middle-mile" infrastructure to connect communities to the Internet backbone.   This money is to be spent for new network deployments.  They will also include programs to promote broadband adoption and to fund public computing centers.  Besides Georgia, other projects in the first set will be in Maine, New Hampshire, Ohio, Arizona and Alaska.

The U.S. Departments of Commerce and Agriculture will award the remainder of the $2 billion on a rolling basis over the next 75 days.  So at long last, the dispersal of the $7.2 billion in total broadband stimulus funding set aside in the American Recovery and Reinvestment Act begins in earnest. The agencies overseeing the funds -NTIA and RUS- have already made modest grants to organizations in 18 states and the District of Columbia for efforts to map broadband coverage. (NTIA and RUS officials had told a panel of Senators in October that the initial awards would be delayed due to a flood of applications for grants and loans seeking a total of $28 billion.  That was more than seven times the amount that was made available in the first tranche of funding.)  

Joined by Gov. Sonny Perdue, Biden told a crowd of workers, business leaders and lawmakers that creating the networks could help smaller businesses compete globally.   "We’re forming the tools that will fashion the work of the 21st century," Biden said. "We are laying the foundation for the economy of tomorrow."  He also tied broadband to the future success of the country’s manufacturing industry and middle class.

"We were losing ground for the past 25 years in manufacturing," Biden said. "We don’t want an economy built on another bubble. We want to do what our grandparents did … and build on a solid foundation."  He also tied broadband to the future success of the country’s manufacturing industry and middle class.

"These critical broadband investments will create tens of thousands of jobs and stimulate the economy in the near term," the White House National Economic Council said in a report accompanying today’s announcement. "By providing broadband-enabled opportunities to previously underserved communities, these investments will also lay the foundation for long-term regional economic development and foster a digitally literate workforce that can compete in the new knowledge-based economy."

The administration plans to award a total of $2 billion in grants and loans on a rolling basis over the next 75 days as it starts doling out the first round of stimulus funding for broadband, which Biden said could be used to help struggling rural areas like Dawsonville with distance learning, telemedicine and real-time pricing for farmers.

The awards are targeted to accommodate four primary missions:

• Middle Mile: $121.6 million to build and improve connections to communities lacking broadband access.
• Last Mile: $51.4 million to connect end users like homes, hospitals and schools to the middle mile network points.
• Public Computing: $7.3 million to expand computer center capacity for public use in libraries, community colleges and other public venues.
• Sustainable Adoption: $2.4 million to fund innovative projects that promote broadband demand "with population groups where the technology has traditionally been under-utilized."

The Department of Agriculture also announced $53.8 million in funding for eight projects on Thursday, and the Commerce Department announced $129 million in funding for 10 projects. Those projects together also will put up another $46 million in matching dollars.

The Recovery Act requires NTIA and RUS to allocate all of the $7.2 billion by Sept. 30, 2010.

Here’s a summary of three Clearwire presentations:

1. Clearwire’s Scott Richardson confidently stated that “spectrum trumps technology” and that “the spectrum owned will separate WiMAX from LTE.”

Mr. Richardson made another interesting observation: “Most 4G wireless networks are limited by self interference (i.e. Self NEXT), rather than how far the signal can travel.” We interpreted this to mean that mobile WiMAX does not produce the self interference than LTE, as we don’t know of any other “4G wireless networks.”

In a somewhat ironic statement, Mr. Richardson said, “new applications drive bandwidth consumption.” With an average of only 100ms round trip latency, developers are able to deliver “more snappy applications, at higher speeds than 3G.” We wonder if that performance advantage, by itself, will be sufficient to entice application developers. especially with no hand held devices available?

Continuing, Mr. Richardson very confidently stated, “We have a super fast (wireless broadband) network which you can think of as a bit factory” for all IP traffic- for both households and machine-to-machine (M2M2) applications. The bits will go to retail or wholesale customers (MVNOs). In the future, we will have other wholesale customers that will use CLEAR as a backbone network. Our evolving business model(s) will enable a whole new set of applications. This will enable a richer web experience for mobile users. Clearwire will have U.S. nationwide coverage by 2011 and will be able to fill the broadband mobile Internet vortex. By 2011, the killer 4G application will be cloud computing on the go.”

2. Clearwire Developer Program Initiatives:

Disclaimer:  many of the items described are "works in progress

Clearwire hopes that the two platforms described here and others to come (see below) will be exploited by independent software developers to build new applications that will make CLEAR service more attractive to subscribers.

According to its Developers web site
( http://developer.clear.com/innovation), Clearwire now offers two types of platforms to provide its customers with an end-to-end solution to develop, implement, and activate Clearwire’s suite of services.

“The Clearwire Location Platform, or CLP, is for developers with location-based services. Developers can leverage Clearwire’s enhanced and dynamic location interfaces to develop cutting-edge location-based services that are an integral part of their website or application.” More about location in the section below.

“The Clearwire Client Connectivity Platform is for developers who want a platform-independent framework to connect to the entire WiMAX network using a device that complies with the WiMAX Forum-supported Common API. The Client Connectivity Platform leverages a new WiMAX Connection Manager and provides public APIs for developers to manage their devices and connections.”
 

3.  Functional modules available (soon) to apps developers and device makers

At the October 27th Sprint Conference 4G Developers” session, Clearwire disclosed many functional modules or capabilities that developers could use to create new apps for mobile WiMAX. The common API was said to be implemented in WiMAX I/O drivers from Intel, Comsys, Samsung and Beceem chip sets. There may be other WiMAX silicon vendors also implementing that API. The new modules (platforms?) that applications will be able to use include:

–Location*: client/server to determine device’s location; server/server to determine location of a device owned by a friend or family member (see details below).
–Access Authentication: using a secure mutual certificate.
-RF Awareness: will be very important for mobile video apps. Signal strength, signal quality, transmit power and other RF parameters will be made available to the application/ video player to enable it to dynamically adjust resolution, frame or data rate (perhaps even change the encoding/decoding/compression scheme?). Note that in a mobile video streaming or 2 way real time video chat/conferencing environment, the received signal quality is constantly changing. So dynamic video parameter adaptation is essential in providing a good video experience to the mobile user.
-Data Session continuity: keep data sessions up while switching between WiMAX, WiFi, EVDO/ CDMA
-Device Management: will be device dependent
-Connection Management*: Connecting and disconnecting a device to the CLEAR network
-Diagnostics: for enhanced troubleshooting
-Service Level QOS: is targeted for end of 2010 or 2011. It will allow the application to request a “better level of service” for selected traffic types, e.g. voice, real time video conferencing, emergency/1st responders, etc.

*These modules are described on the CLEAR developers web site

Clearwire sees location as a key enabler for the types of services that take advantage of WiMAX bandwidth and mobility.

-Client/Server location is based on the Call Sector (1/3 of a Cell) that the device is physically present. No GPS or client hardware is required. The result provided is a longitude/ lattitude for the center of the Sector. A corresponding street address may be optionally requested. Acccuracy was said to be withing 400m to 800m. Computation time is < 1 second.

-Server/Server location allows one server to ask another for a remote device location using the latter’s IP or 802.16 MAC address. The resulting response is the longitude/ lattitude for the center of the Sector the remote device is in.

-Assisted GPS capability is targeted for sometime in 2010. In this scenario, GPS queries the network service to more quickly fix the device location.

-Multi-lateration is targeted for late 2010. In this situation, a given device type is connected to more than one Base Station located in different Sectors.

The IEEE 802.16 Working Group met in its Session #64 the week of 16 November 2009 in Atlanta, GA, USA. The IEEE 802.16 Session #64 Report summarizes the outcomes

–From IEEE Contribution 802.16-09/0023 -Project Planning Adhoc Report (by Jose Puthenkulam; 2009-11-17):

Smart Grid:
An IEEE 802.16 GRIDMAN Study Group (SG) on "Greater Reliability In Disrupted Metropolitan Area Networks" has been created. The proposal was approved by the IEEE 802.16 WG and the IEEE 802 Executive Committee. It will study the synergies among IEEE 802.16 wireless metropolitan area network technologies aimed at Smart Grid, Public Safety, Avionics, Airport Surface Communication, and Surveillance applications. The SG needs to create an adhoc/plan for engaging with the NIST Smart Grid project and co-ordinate with other IEEE 802 WGs on this topic. It will first meet at IEEE 802.16 Session #65.
