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
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
I see and hear a lot of confusion about next generation networks (NGN). In most cases people are using the term roughly as the ITU-T defines it: "A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies." but many people don't realize how little this has to do with the Internet... more
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. more
Last Friday (HT: IPDemocracy), Google filed a petition [PDF] asking that the Commission ensure that Verizon understands what those "open platform" requirements for the C Block really mean. Verizon has taken the position in the past that its own devices won't be subject to the "open applications" and "open handsets" requirements of the C Block rules, and Google says it is concerned that Verizon doesn't plan to follow those requirements in the future. This is big. Here's the background... 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
One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more
The New Jersey Supreme Court has issued an important decision on Internet users' right to privacy. The case involves a dispute about whether an ISP violated a user's privacy rights by turning over subscriber information (name, address, billing details) associated with a particular IP address. It ends up that the subpoena served on the ISP was invalid for a variety of reasons. As the user had a 'reasonable expectation of privacy' in her Internet activities and identifying information, and because the subpoena served on the ISP was invalid, the New Jersey court determined that the ISP should not have turned over the personal data... more
