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.
Carlson Wireless has developed RuralConnect IP, a software-defined radio that uses TV white spaces to deliver wireless broadband service to homes, businesses and municipal entities in rural and underserved areas.
In wireless communications, spectrum inherently is the lifeblood of operations. Without spectrum, all the technology in the world is worthless in terms of establishing and maintaining a wireless network. This reality makes last week’s launch of the first network operating on the unused frequencies between active TV channels, known as TV white spaces, in the small town of Claudville, Va., extremely notable.
