Evidence mounts for using white spaces for rural broadband

摘要

A trial conducted at Microsoft's research laboratory in Cambridge, England, late last year demonstrated that using TV white-space spectrum to deliver broadband services to rural and underserved areas - and to fill in urban coverage gaps - works well and without interference to incumbent broadcasters, according to Jim Carlson, president of Carlson Wireless, one of the equipment vendors that participated in the event. The trial, which involved numerous field tests, was conducted over six months.
