Wireless system @transmission at 3Gbps

A team of researchers at the Tokyo Institute of Technology have developed a new wireless transmission system. The systemt works at the range of 300GHz to 3THz (terahertz), which is the Far Infrared (FIR) frequencies spectrum. That spectrum is currently totally unregulated by any country or standards organization in the world, making it ripe for development of new technologies. So far the Japanese researchers have transmitted data at 3Gbps, but in theory speeds of up to 100Gbps should be possible.
The new “T-ray” wireless transmission system is similar to WiGig in that it requires line of sight and can transmit large amounts of data at once. However, WiGig runs at “just” 60GHz, meaning it can actually work with distances larger than a couple of meters without significant power boosting. This T-ray system will be limited to 1-3 meters without significant power boosting. With power boosting, it could match or surpass WiGig in range.

walmart slashed iphone prices

 WALMART SLASHED IPHONE PRICES

Walmart reduced the prices for the AT&T version of the iPhone 4 and iPhone 4S on Friday,The 8GB iPhone 4 was reduced from US$88 to $34 with a two-year contract, and at least in one store the 16GB iPhone 4S price had dropped from $188 to $114. The Walmart website, however, lists the iPhone 4 at $117 and out of stock, while tagging the iPhone 4S as “Store pricing may vary.”

With the launch of the iPhone 4S, the iPhone 4 dropped in price and became available in only 8GB form. The iPhone 4S on the other hand is available in three sizes, 16GB, 32GB and 64GB. The iPhone 4S has been out since October and it has become the top selling phone on AT&T and Verizon and presumably at Sprint as well.
