A team of Scientists in Pisa, Italy are reported to have set a new world record in wireless data transmission speed. Italian researchers from Sant'Anna University along with the Japanese Waseda University and the National Institute of Information and communication technology in Tokyo, for the "first time in the history of telecommunications" achieved throughput speeds of above 1.2 Terabits per second. Previous record, set in Korea, had been160 Gigabits per second. more
The WiMAX Forum has released an Interactive Deployment Database, providing a resource of more than 300 WiMAX deployments across the world. Available for public use, this tool includes detailed information on each of the operators, stage and type of deployment, as well as spectrum utilized. The database is planned to be updated quarterly with the latest information. more
Last week American Airlines launched their Aircell wireless Internet access on a limited number of flights. It didn't take long before a few folks tried to make voice and video calls (in violation of Aircell's terms-of-service according to their PR folks), and it didn't take long before someone figured a way around their voice/video blocking efforts. more
The Federal Communications Commission (FCC) has proposed a ban on some wireless microphones and other low-powered devices that operate in the 700-MHz band after the digital TV transition in February, next year. This is part of an attempt to clear any potential interference with the "white spaces" spectrum which will be fully available for "public safety as well as commercial wireless services". more
Both the Internet and North American cellphones are choking under a 32 bit limitation and reactions from protagonists involved in both cases offer striking similarities. 1983 saw the debut of IPv4 and North American mobile telephony started in earnest with Bell's analog AMPS (Advanced Mobile Phone Service). Responding to the need to uniquely identify the growing number of mobile devices in order to bill their owner, the FCC ordered that handsets be equipped with a unique identification number embedded on a chip. This became the 32 bit ESN... more
What could be bad about free wireless Internet access? How about censorship by federally mandated filters that make it no longer "Internet." That's the effect of the FCC's proposed service rules for Advanced Wireless Service spectrum in the 2155-2180 MHz band, as set out in a July 20 Notice of Proposed Rulemaking. Acting on a request of M2Z Networks, which wants to provide "free, family-friendly wireless broadband," the FCC proposes to require licensees of this spectrum band to offer free two-way wireless broadband Internet service to the public, with least 25% of their network capacity. So far so good, but on the next page, the agency guts the meaning of "broadband Internet" with a content filtering requirement. more
The news that Comcast, Time Warner, and AT&T are all considering capping use of their networks -- so that "overuse" would trigger a charge -- has prompted intense discussion of just why these network operators are moving in this direction. One camp suggests that these operators have to do *something* to manage congestion, and because any protocol-specific discrimination plan raises howls of protest from the Net Neutrality side of the fence adopting bit-usage discrimination schemes is inevitable. It's the least-bad approach, following this view. more
Google co-founder Larry Page came to Washington last week to take on the National Association of Broadcasters (NAB), the lobbying group that represents over-the-air television stations. It's a whole new adversary for the beleaguered broadcasters, who have been fighting cable and satellite television for years. The Federal Communications Commission is currently considering a proposal, by Google and other tech players. It would allow tech companies to build electronic devices that transmit wireless internet signals over the "white spaces," or the vacant holes in the broadcast television band. "We have an ambitious goal called pervasive connectivity through ubiquitous broadband networks," said Page... more
The long rumored reorganization of the telecommunications sector in China has begun. Now China will have three major companies, each with both mobile and fixed networks. The focus for fixed network growth is broadband Internet access. The focus for mobile will be continued growth in mobile subscribers and the launch of 3G services, with the three companies using three different 3G technologies. more
There is a germ of truth (perhaps a prion-sized germ or maybe just an amino acid) in the idea that transmitters in "white spaces" in the TV band *might* disrupt patient monitoring equipment if designed by a lunatic who believes in sending massive pulses of energy in a whitespace in the TV band (perhaps amplified by a large parabolic dish antenna the size of a trashcan lid or larger, aimed at the patient monitor system. But that risk is completely shared with zillions of other potential radiators of energy in the entire electromagnetic spectrum... GE, of course, owns NBC. There is a MAJOR conflict of interest at the corporate level of GE... more
The new Clearwire could be game-changing, but the rules of the game may not be quite as Clearwire presents them. I have been wondering since last July whether something significant would happen in the Google/Sprint world. The deal announcement earlier this weekseems to be that key development... In a nutshell, Sprint will contribute its substantial spectrum licenses in the 2.5 GHz range and its WiMAX-related assets and intellectual property. Google, Intel, Comcast, Time Warner Cable, and Bright House Networks will invest a total of $3.2 billion. more
Last week there was a flurry of stories about China's 3G plans after Jonathan Dharmapalan of Ernest & Young was quoted as saying he expected it to take 12 to 24 months from the start of China's commercial TD-SCDMA trials, i.e. from now, until 3G licenses were issued. But there was little analysis or comment on what's really happening. 3G licenses are a formality. They delay the deployment of 3GSM & CDMA 2000 which could otherwise happen rapidly -- just plug new cards into existing radios and offer established handsets (already being manufactured, in China, for the world market). more
Modern travel means interminable waits, but it's a good time for reading. I finally read Wireless Pittsburgh: Sustainability of Possible Models for a Wireless Metropolitan-Area Network by Jon M. Peha, published in February as a working paper of the New America Foundation. The good news: it's full of interesting cost estimates and projected subscriber take rates based on specific demographics in Pittsburgh, Minneapolis and Philadelphia... The flaws in this study...

In February, the FCC's Office of Strategic Planning and Policy Analysis published three studies (1, 2, 3) on spectrum licensing and spectrum utilization. Thanks to Nick Ruark for pointing them out... Reading on I was struck by a gaping hole in their assumptions. more
The white spaces proceeding is the next big opportunity for experiments in alternative ways of providing wireless highspeed internet access... A key advantage of unlicensed spectrum is that experiments in new technology can be carried out without asking the permission of spectrum licensees. To date, we have made very little spectrum available for unlicensed use and experimentation. The FCC has the discretion to decide whether the digital television "white spaces" may be used on an unlicensed basis... more
