Professor Allen Hammond, Director of the Broadband Institute of California, offers a perspective on the importance of broadband access and a prescription for making it available and affordable for all U.S. residents.  Recommendations for Digital Inclusion, U.S. Broadband Policy, a national wireless network, funding and measurement tools are also included in this interview. 

Most of us take broadband Internet access for granted.  We watch videos, play music, multi-media games, upload and download large files without even thinking about it.  But not everyone in the U.S. is that fortunate.  A large number of the U.S. population lives in rural or “underserved” areas where broadband access is not available.  Many low income, inner city residents can’t afford cable or DSL based broadband access.   And municipal wireless networks that were promised to provide such access for cities and counties have been delayed or cancelled. 

Those without affordable access to broadband are at a competitive disadvantage; they are at risk of being marginalized and left behind, as more and more mandatory services migrate to the broadband Internet.  Today, most skilled jobs require PC and web based interfacing skills, which are more likely to be learned by those that have broadband Internet access.  Government services (such as Unemployment and Disability claims), education and training (including webinars), health care, travel information, and banking are offered on-line and have become pervasive on the web.  But without broadband access, these services are not conveniently or easily available.  What if you’re bank branch office has been recently closed and you’re told to do most of your banking on-line?  What if you’re applying for a job that requires web surfing, quick access to information, uploading or downloading .ppt or zip files from web sites?  Not good if you don’t have broadband Internet access or related skills.  Those that don’t will be left behind. 

Professor Hammond firmly believes that “Broadband access is a civil rights issue.”  It should not matter if one lives in a sparsely populated or rural area, an inner city, or a suburb.  Rich or poor shouldn’t matter either.  Broadband access should be made available to all that want it at affordable rates.

What’s Digital Inclusion and Why Is It Important?

The Wired for Wireless? Summary Report¹ uses the term “Digital Inclusion” to denote the ability of everyone to have access to broadband and the related information technology.  Specifically it states:  “Digital Inclusion means that everyone — regardless of who they are or where they live — can participate in and take advantage of the economic, educational, health, and civic opportunities afforded by broadband and related information technology. 

More than just access to the Internet, Digital Inclusion means that all stakeholders are engaged in the planning and implementation of technology systems; that all potential users can access the technology and know how to use it; and that with these technologies come more services, increased information, and greater community access. As digital technology is increasingly used for educational, employment, health, commercial, and informational purposes, Digital Inclusion is critical for full engagement, participation, and opportunity in the social, economic, and civic life of society.” 

The report found that “wireless networks are effectively supporting government operations and services. Wireless technology is being used for a large range of government tasks: traffic light control, meter reading, data transport from regional offices to headquarters, video surveillance, communication between emergency vehicles, and much more. These projects have proven successful when jurisdictions commit funding toward the deployment and maintenance of the network.   Project research indicates that many local governments in California pursued or are pursuing a wireless network in order to bring broadband access to underserved communities. In most of these cases, the wireless networks were intended to enhance or fill in gaps left by existing deployment.”  However, the deployment of most of those CA municipal wireless networks, e.g. Wireless Silicon Valley, San Francisco, Fresno, etc have gone into hibernation status or they’re just plain dead.

U.S. Government Broadband Stimulus and Plan

The U.S. is one of the few developed countries that does not have a national broadband plan and up till this year, has done little to accelerate or drive broadband deployment.  The federal government has taken the position that broadband Internet is the job of the private sector.  This is in sharp contrast to the public sector build out of roads, highways and bridges.   

On February 17th, 2009, the American Recovery and Reinvestment Act of 2009 (Recovery Act) became law.  This was the government’s first step to making broadband more available in the U.S.  In particular, the Act allocated $7.2 billion in grant and loan funds for broadband build-outs.

India’s 3G and WiMAX spectrum auctions are planned to commence this year paving the way for Mobile Internet and Fixed Broadband Wireless Access.

Introduction

India’s IT/ Telecommunications Minister, Andimuthu Raja, has stated that the government will start the auction of licenses for high-speed wireless services within the next three months.   Many feared that the long delayed auctions might not start until sometime in 2010, so this could be good news.   In November 2008, India’s Telecommunications ministry picked NM Rothschild & Sons Ltd.  as the independent auctioneer to help it sell the permits and aimed to complete the process by early 2009, but that never happened.

The auction to operate 3G mobile-phone services and fixed wireless broadband (WiMAX) services will earn India about 250 billion rupees (US$5.1B), Raja said.   The starting price for each slot of 3G spectrum is 35 billion Indian Rupees (US$716M), lower than the (US$827M) price previously signaled by the government but higher than the original (US$413M) price suggested.   "Since the number of slots are only four, the auction price will be more," Raja said.  

Three available blocks of spectrum in the 2.3 and 2.5GHz band will be auctioned separately for fixed broadband wireless access services.   The so called "WiMAX auction" will be held after the 3G auctions are completed and are expected to follow a similar process.   The government ministers also set a base price of 17.5 billion rupees for permits to operate fixed broadband wireless (WiMAX) services.

As noted above, the 3G and WiMAX spectrum auctions had been scheduled to take place in January this year, but were subject to repeated delays that have allowed government controlled operators BSNL and MTNL to deploy 3G services ahead of privately owned rival carriers.   Those operators had already received licenses for one of the five blocks of spectrum to be allocated for wireless broadband (more in the next section of this article).

It was hoped that early auctions of 3G and WiMAX licenses would result in a growing market for mobile Internet in India, which has much potential and promise.   India is now the second largest wireless market in the world, but almost all of it comes from cellular voice and SMS (rather than from wireless Internet access).   India’s cellular operators added 11.59 million subscribers in May, taking the country’s total to 415.25 million, according to the latest figures from Telecom Regulatory Authority of India (TRAI).

Introduction:

Managed services and outsourcing of wireless and wireline network operations has become an emerging trend in the global telecom industry. 

Here are a few recent examples:

-Last year, Embarq outsourced its Network Operation Centers (NOCs) to Nokia Siemens Networks (NSN).
-In a blockbuster deal announced a few months ago, Sprint announced it will pay Ericsson as much as $5 billion over seven years to manage its CDMA and iDEN wireless networks as well as its fixed-line network.
-Alcatel-Lucent has joint ventures with Indian operators Reliance and Airtel for mobile and fixed networks, respectively.
-Light Reading stated this week that Huawei has made significant strides in its managed services provisions in India. The Financial Times reports that BT will outsource the upkeep of its local phone network to a joint venture of Carillion and Telent, in a £1bn deal expected to be agreed in the next two months.
-WiMAX rural operator Open Range today announced an agreement with IP backhaul vendor Harris Stratex to run its NOCs for five years.
-Bharti Airtel signed a managed services deal with Comviva, making it the first telco in the world to have a managed services agreement for all its value-added services portfolio.

Rajeev Suri, Director of NSN’s managed services business unit says the global managed services is a $277 billion market.  Which carrier will be next to outsource its operations? Will that make them more competitive and profitable? And how much new managed services business will traditional network equipment vendors get?  We focus our attention on the new managed network players in this article.

The new kids on the Managed Network block include Huawei,  Carillion and Telent joint venture, and Harris- Stratex.

Opinion:  The newer, greenfield operators that don’t have any experience in managing networks or operations might be better off by outsourcing network operations and/or managed services/ NOCs.

What’s your opinion?  Do you think Clearwire would do well by outsourcing its network maintenance and management services to another vendor?

Mobile Internet Data Traffic Trends and  Implications for the Wireless Industry

Can the growth of mobile data live up to the hype given the current capacity of wireless networks? Interview with Andrew Odlyzko, Professor of Mathematics at the University of Minnesota and expert on internet traffic patterns and growth.

Introduction:

Due to the success of smart phones, app stores, and open platforms, a strong consensus now holds that mobile data is creating the next telecom revolution.  The volume of data transmitted over mobile wireless networks is skyrocketing, growing at rates over 100% per year. 

But is that growth rate sustainable? Bandwidth per user will continue to be limited by overall 3G-network capacity.  Moreover, considerable CAPEX would be required to upgrade mobile networks to 4G.  Also, most subscribers are unwilling to pay rates in excess of $50 or even $70 per month, which most mobile operators need to get a reasonable ROI .  Yet wireless data growth conjures up "visions of sugar plums" for many telecom professionals and wireless industry stakeholders.

To examine the hype vs.  reality of mobile Internet data growth, we checked in with Professor Andrew Odlyzko – a former AT&T Researcher who exposed the myth of exponential (wireline) Internet traffic growth back in 1998 – just prior to the dot com bust and optical networking melt down.  Odlyzko has been tracking Internet traffic trends for over 12 years.  During most of that time period, the actual traffic growth did not live up to the over-hyped projections.

Here’s the lead-in:Realizing the Mobile Internet- new functions, technology and innovative applications

Abstract:

In the second article resulting from our in depth interview, Siavash Alamouti, CTO of Intel’s Mobile Wireless Group comments on the roadmap, potential new applications, functions, and technical requirements for 4G mobile networks. Specifically, he envisions several intriguing mobile Internet applications and value added services, delineates major performance and feature upgrades for 4G (it is not an evolution from 3G as many think), identifies several technical issues/ problems to be resolved, and explains why LTE is not the panacea many believe it to be.
 

Introduction

While the pump is primed for mobile broadband, significant investments in next-generation broadband wireless networks will be needed to deliver on the promise and potential of the mobile internet experience.   If that is not the case, then all the predictions for explosive mobile Internet growth are a myth- similar to the Internet traffic growth stories of the late 1990s

Report of IEEE 802.16m Meeting -Session #62 on 13-16 July 2009 in San Francisco, CA

Most notably, the IEEE 802/16 Working Group met a major milestone by agreeing to open a letter ballot on the first draft (P802.16m/D1) under the 802.16m project. The 16m Task Group will issue a request for input on specific technical topics (LBS, E-MBS, Relay, and SON- see below for acronym definitions), to be submitted prior to Session #63 in Jeju, Korea and discussed at Session #63.5 on the big island of Hawaii.

The IEEE 802.16 Session #62 Report summarizes the outcomes:

http://ieee802.org/16/meetings/mtg62/report.html

From Jose Puthenkulam, IEEE 802.16 Vice Chair:

The important news items are:

– The first IEEE 802.16m Draft Standard (D1) will be issued shortly, before August 1st.

– The 802.16 Working Group Letter Ballot on the IEEE 802.16m Draft Standard will start soon after.

– A lot of contributions (60) on 802.16m Femto-cells were submitted last week. Work on Femtocells will continue throughout the letter ballot phase.

– Also optional features like Enhanced Location Based Services (LBS), Enhanced Multicast-Broadcast Services (EMBS), Integrated Relay and Self Organizing Networks (SON) will start being developed soon.

– The IMT-Advanced Proposal development also progressed very well. The complete proposal will be ready by mid September and finalized by the Sept 21-24 Hawaii meeting.

– IEEE 802.16m Systems are expected to deliver performance >300Mbps in 4×4 MIMO configurations using 20MHz channels

From Siavash Alamouti, CTO of Intel’s Mobile Wireless Group – on IEEE 802.16m capabilities in the 2010-2011 timeframe:

-Peak sector throughput over 300 Mbps Downlink* (in a 20 MHz channel)
-TDD & FDD support
-Multi-carrier support; BW of up to 100 MHz
-Increased VoIP capacity
-Even lower link access latencies
-Enhanced coverage
-Enhanced multi-radio coexistence and inter-technology handover
-Integrated multi-hop relay
-Self-organizing base stations
-Increased mobility: Up to 350 km/hr*

*Note: Actual mobility & throughput depends on environmental conditions and Service Provider provisioning. Aggregate peak sector throughput calculated using 20 MHz channel for Downlink.
