Ultra-fast wireless data transfer – download a whole DVD in 3 seconds

Just how fast does wireless data transfer have to get before it ceases to be a limiting factor in application design? Researchers in Georgia are working on new ultra-high-frequency radio technology that has already achieved a phenomenal 15 gigabits per second (Gbps) over short distances. For reference, that’s a whole DVD worth of data transferred in a little over 3 seconds – and they’re hoping to double that speed within 12 months. With such transfer rates available, high-definition media streaming and file sharing becomes a blink-and-you’ll-miss-it affair. Backups and full hard drive synchronization between different machines will be quick and painless, and distributed application and file sharing around networks will become, for the most part, something the user will simply not have to think about. It’s estimated at about three years from hitting the market, but this amazing technology is set to make big waves.

New research at the Georgia Institute of Technology could soon make that tangle of wires under desks and in data centers a thing of the past.

Scientists at the Georgia Electronic Design Center (GEDC) at Georgia Tech are investigating the use of extremely high radio frequencies (RF) to achieve broad bandwidth and high data transmission rates over short distances.

Within three years, this “multi-gigabit wireless” approach could result in a bevy of personal area network (PAN) applications, including next generation home multimedia and wireless data connections able to transfer an entire DVD in seconds.

The research focuses on RF frequencies around 60 gigahertz (GHz), which are currently unlicensed—free for anyone to use—in the United States. GEDC researchers have already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters.

“The goal here is to maximize data throughput to make possible a host of new wireless applications for home and office connectivity,” said Prof. Joy Laskar, GEDC director and lead researcher on the project along with Stephane Pinel.

GEDC’s multi-gigabit wireless research is expected to lend itself to two major types of applications, data and video, said Pinel, a GEDC research scientist.

Very high speed, peer-to-peer data connections could be just around the corner, he believes – available potentially in less than two years.

Devices such as external hard drives, laptop computers, MP-3 players, cell phones, commercial kiosks and others could transfer huge amounts of data in seconds. And data centers could install racks of servers without the customary jumble of wires.
