British mobile bandwidth hogs won't have to curb their data enthusiasm anytime soon if a scheduled ' super WiFi ' trial minds it manners. Led by Microsoft and backed by the UK's biggest TV providers, this roided-up wireless network surfs along the spare 150MHz spectrum that terrestrial television avoids. Christened the ' white spaces ,' networks abroad (and in the US) maintain these unused frequencies to prevent signal interference, but with MS' Dan Reed calling spectrum "...a finite natural resource," operators don't have much else to mine. Set for testing in Cambridge -- chosen for its dense cluster of buildings old and new -- this repurposed TV signal walks through walls its weaker mobile brethren smack into (at up to 16Mbps, no less!). With a similar British Telecom rollout already underway in Scotland, we'd say the tech has an imminent Anglo-future -- pity the US can't seem to unravel the red tape fast enough for a homegrown build-out.[Image credit via ZDNet UK
