> The chip, just 5 mm per side, has a tiny 1 mm antenna and uses the 60 GHz 
> 'millimetre-wave' spectrum - an unlicensed band of 7 GHz between 57 GHZ 
> and 64GHz.
> NICTA's CEO David Skellern says the technology will allow the wireless 
> transfer of audio and video files at rates up to 5 gigabits per second. 
> almost ten
> times faster than what is currently possible. And the fabrication which 
> uses a 130 nanometre CMOS process, may lead eventually to chips priced as

> An IEEE Task Group no. 3C was formed in 2005 to develop this new WPAN
