New wave for wireless

An extra radio band will turn congested networks into a Wi-Fi
version of the autobahn
a second radio band at five gigahertz is being opened to bypass the crowding and boost the speed of today's home and office wireless networks, which run on the original Wi-Fi band of 2.4GHz.

"Five gigahertz lets you create what we call an 'entertainment-grade' network for online gaming from your Xbox or PlayStation as well as moving all your video and audio, all your high definition multimedia content, around your home to a TV screen," says Graeme Reardon, regional director for Linksys Australia and New Zealand.

"At the same time you can keep 2.4GHz for what we'd classify as your data network, which is email and web browsing and things like that."
