Wireless News: Microsoft SPOTs a New Opportunity "What is particularly intriguing about Wednesday's announcement is that the SPOT devices will use a nationwide WAN (wide area network) based on FM subcarrier technology, much like that used by the Muzak piped-in music service.
Dubbed DirectBand, the technology includes a custom radio-receiver chip and new radio protocols to transmit information to smart objects via FM broadcast bands. By using radio frequency, Microsoft has access to nearly every FM station in the country. DirectBand's initial coverage area will include some 100 of the largest population centers in North America, the company said, representing cities in all 50 states and in Canada.
Broadcasters Clear Channel Communications, Entercom Communications, Greater Media and Rogers Communications are among those working on the project with Microsoft."
