Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes is implemented without the use of wires, such as a computer network. Wi-Fi is a commonly used wireless network in computer systems which enable connection to the internet or other machines that have Wi-Fi functionalities. WiMAX, the Worldwide Interoperability for Microwave Access, is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. One example of an important use for wireless networks is as an inexpensive and rapid way to be connected to the Internet in countries and regions where the telecom infrastructure is poor or there is a lack of resources, like most developing countries.

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»
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»
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...

Scott Cleland claims the open access rules on 700MHz spectrum triggered by Google's bid fleeced the US taxpayer by $7bn. I don't buy it, even as a signed-up fully-paid network neutrality opponent. Firstly, the numbers ignore economics. If the C block was encumbered, that would raise the prices of the A and B blocks. So you need to take a much smaller differential as to the cost of the encumbrance. more»
By providing mobile and fixed-line operators with a single routing mechanism, PathFinder simplifies and reduces the cost of delivery of a wide range of IP-based services to end-users. It will serve as a central 'directory' for all operators, and enables them to rapidly launch new IP services. ›››

When the .mobi domain launched in September 2006, people quickly understood it was a Top-Level Domain (TLD) designed to locate mobile content in the same way - for example - that .se locates Swedish content or .museum helps users recognize genuine museum activity. In short, think "mobile phone" when you think ".mobi". Now, the .tel domain is launching... So do you still need a .mobi domain? ›››
