Short range wireless transfers at 15 Gigabits per second

Forget about USB and Firewire with its cables. Georgia Tech is promising very high speed wireless peer-to-peer data transfers in a couple of years:

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.

I use Bluetooth for connecting to the internet via my mobile, synchronizing my PDA etc but Bluetooth is too slow for devices requiring high data transfer rates like hard disks, video cameras, streaming etc. Transfer rates of 15 Gbps means that it can replace cable in most cases.

I thought it would be outright dangerous to be close to a something transferring data via radio at 15Gbps but it looks like I am wrong:

Even when sitting on a user’s desk, Pinel stresses, a multi-gigabit wireless system would present no health concerns. For one thing, the transmitted power is extremely low, in the vicinity of 10 milliwatts or less. For another, the 60 GHz frequency is stopped by human skin and cannot penetrate the body.
