Published in the April 2003 issue of the Journal on Selected Areas in Communication, this tutorial paper introduces "multiple-input-multiple-output (MIMO) space-time coded wireless systems" and discusses recent progress in their design and performance. Hailed as a breakthrough emerging technology that has profound implications for digital communications, these systems have the potential to resolve...
The University of New Hampshire has compiled this excellent collection of resources on networking and computer technology. Over twenty categories are represented, including emerging technologies such as 10 Gigabit Ethernet, Very high rate Digital Subscriber Line (VDSL), and wireless standards. Many of the resources are papers or tutorials written by researchers at the UNH InterOperability Lab,...
This Web site is the homepage of an initiative to create a new Java specification for wireless devices. Several documents are available for public viewing, including the Proposed Final Draft of the specification, which was released on June 4, 2003.
This is the home page of the Mobile Manufacturer's Forum, an international association of several leading "radio communications equipment manufacturers." Its purpose is to inform the general public about health policies and standards regarding radio frequency (RF) energy emitted by mobile phones and base stations. There are several documents and press releases that can be accessed on the Web site....
In the April-June 2002 special issue of the IEEE Pervasive Computing journal, a team from Carnegie Mellon University contributed with a discussion of their Project Aura. The project's goal is to increase computing efficiency, particularly in wireless environments, so that "distractions such as poor performance and failures" are minimized. With greater system reliability and fewer distractions,...

Pacific Northwest...
Mobile phone users must be conscious of their phone's settings wherever they go, and are required to adjust settings such as ring volume and vibration depending on the surrounding environment. This research paper introduces SenSay, an intelligent mobile phone system developed at Carnegie Mellon University that is designed to eliminate the constant attention required by current mobile phones. "It...
Created by the Pew Internet and American Life Project, this report focuses on the nature of broadband --- high speed communication --- use in American homes. The report reveals that nearly 24 million Americans (21% of all Internet users) have high-speed connections at home; as a result, they are able to spend more time online and perform more activities within a shorter period of time than dial-up...
