Faster Wi-Fi in works to transfer movies, other large data files
With a wave of his hand over a homemade receiver,Georgia Tech professor Joy Laskar shows how easily — and quickly — large data files could someday be transferred from a portable media player to a TV. USA Today reports.
"While Wi-Fi and Bluetooth have emerged as efficient ways to zap small amounts of data between gadgets, neither is well suited for quickly transferring high-definition video, large audio libraries and other massive files.
Laskar and other scientists at the Georgia Electronic Design Center have turned to extremely high radio frequencies to transfer huge data files over short distances.
The high frequencies — which use the unlicensed 60 gigahertz band — have been a mostly untapped resource. Researchers say it could one day become the conventional wireless way to zap data over short distances."
