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.

Moreover, Pinel said, users of multi-gigabit technology could wirelessly connect to any device that currently uses Firewire or USB. Wireless high-definition video could also be a major application of this technology. Users could keep a DVD player by their side while transmitting wirelessly to a screen 5 or 10 meters away.

Currently, Pinel said, the biggest challenge is to further increase data rates and decrease the already-low power consumption, with a goal to double current transmission rates by next year. The Georgia Tech team is seeking to preserve backward compatibility with the WiFi standard used in most wireless LANs today.
