The Federal Communications Commission (FCC) today approved, in a 5-0 unanimous vote, the plan to open up unused, unlicensed portions of TV white space spectrum for wireless applications and devices. However, to prevent interference, FCC has also placed some "rigorous certification process" which device offered by a technology company for use on the white spaces will have to go through. more
The Federal Communications Commission (FCC) has just voted to open up the so called TV Whitespaces for UNLICENSED use. This is incredibly good news for rural America in particular but actually for all of America. It's not as important as the election the rest of us in the US voted in today -- but this action is a very, very big deal. Just a few of the benefits... more
I've been following the "white spaces" for as long as it has been happening -- four, maybe five years -- and I must admit that I am surprised by FCC Chairman Kevin Martin's sudden fondness for them. Until the last days of his chairmanship, Martin never cared for this somewhat radical notion: allowing techies and community activists to spew electromagnetic frequencies in zones currently occupied (at least ostensibly) by the broadcasters. more
Like several other engineers, I'm disturbed by the white spaces debate because it focuses on what I regard as the wrong question. The White Space Coalition argues that showing that a system can be constructed that prevents interference between White Space Devices and television broadcast signals compels the Commission to offer up the White Spaces for unlicensed use. This is far from obvious. more
Google Inc. and T-Mobile USA today unveiled the highly anticipated smart-phone G1, the first in the industry to be based on Android, Google's operating system for mobile phones. Currently available for T-Mobile customers only, the T-Mobile G1 combines full touch-screen functionality and a QWERTY keyboard with a mobile Web experience that includes popular Google services such as Google Maps Street View, Gmail, YouTube and others. The T-Mobile G1 is also the first phone to provide access to Android Market, where customers can find and download unique applications to expand and personalize their phone to fit their lifestyle. more
The Swedish morning daily Svenska Dagbladet on their editorial page yesterday writes about the EU threat to intervene at mobile roaming costs for voice, SMS and data. The editorial is pushing the point that it's wrong for the EU to try and price regulate the market, but instead the free market will prevail. They even seem to be indicating that the current pricing is fair and that an EU price regulation would hamper investments. In very general terms I would agree with the editorial... 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
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
Just about everyone I talk to is very excited about mobile Internet. In 2006, the Japanese government proudly announced that more people used the Internet through their mobile phones than through their computers. Online services are all talking about their "mobile strategy" and VCs are flocking to fund the latest "mobile startup". I don't think there is anything wrong with mobile or with some of the great new mobile applications and devices, but we have to be careful to remember that most mobile networks that actually work are built on infrastructure that is operated by a small number of mobile operators who use a lot of regulated and closed technology... 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
Want a gig (1000 megabits per second) of Internet access bandwidth? Google says you could have it by the end of next year "from Manhattan to rural North Dakota (sic, I think they meant Vermont)" if their proposal to the FCC is accepted forthwith according to CNET's newsblog. Not only a gig but a mobile gig, accessible by cellphone or roaming computer -- no fiber required. Sound too good to be true? -- it isn't, IMHO! Engineering is not the problem... more
Today the FCC announced the winners of the 700 MHz auction -- and you can see from pp. 62-63 of this document that Verizon won Block C. (Block C was set up in two nationwide paired blocks of 11 MHz each, which were auctioned off in very large geographic areas -- 12 licenses, each covering a "Regional Economic Area Grouping". Verizon won seven of the twelve licenses, covering all of the US except Alaska, Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.) Why does this matter? more
Lee Dryburgh initiated a great thread in the Emerging Communications public group entitled What would your perfect phone be? There are 14 messages there at this moment with a lot of good ideas, but my first thought was the term "phone" is too limiting. Indeed, some of the correspondents' ideas also go far beyond the idea of a telephone. Here's what I want and fully expect to see, eventually. more
Comcast has been in the news recently for deliberately "slowing down" some subscribers and applications in its broadband cable service. There was an article in the Washington Post today updating the case, and there was a recent article in Network World that actually favors the groups filing the complaints and calls for the FCC to crack down on Comcast. more
