Telecom in China: After the Dust Settles

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.

Is Mobile Internet Really Such a Good Thing?

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...

The New Clearwire

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.

Sprint’s Big Deal: New Life for WiMax

The Wall Street Journal is reporting the terms of a yet unannounced deal which will finance a massive rollout of WiMax by a Sprint-Clearwire joint venture. Outside funding is to be provided by Intel, Google, Comcast, and Time Warner Cable as well as Bright House, a small cable company. Assuming the deal is for real, this is good news for US users of broadband and, indirectly, other users around the world.

China’s 3G License Delay is a Smoke Screen

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).

Google’s Gigabit Gambit

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...

700 MHz Auction Winners: Why Block C Matters

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?

The Perfect Phone

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.

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world...

WiMAX vs. WiFi

In fact WiFi (technically standard 802.11) and WiMAX (802.16) don't compete for broadband users or applications today. That's partly because WiFi is widely deployed and WiMAX is still largely an unfulfilled promise and partly because the two protocols were designed for very different situations. However, if WiMAX is eventually widely deployed, there will be competition between them as last mile technologies. Some people describe the difference between WiFi and WiMAX as analogous to the difference between a cordless phone and a mobile phone...
