Processor loses 8 percent accuracy, slashes power draw
Researchers from Rice University and other institutions have unveiled an "inexact" computer chip that is built to allow for errors. The design forsakes 100 percent accuracy in an effort to save power; in its current form, the chips are claimed to be up to 15 times more efficient than current technology.
Use would recylcle underutilized TV spectrum
Ofcom, the regulatory and competition authority for the UK communications industry, has approved the use of "white space," the unused segments that exist in the spectrum currently solely used by analog TV broadcasts, for wireless Internet access. The low frequency of this spectrum enables signals to travel long distances and penetrate walls at speeds up to 22Mbps, making it attractive for a wide range of new consumer applications including rural broadband, and behavior like Wi-Fi with up to twice the range of today’s technology.
White space wireless already in live testing
Rice University had the distinction of being the first to implement the recently cleared white space wireless in real-world conditions. Houston restaurant worker Leticia Aguirre has been given a prototype connection that for the first time has given her a reliable Internet link in her area. The addition was part of a larger rollout that would give about 3,000 East Houston locals the long-range wireless access.
