Microsoft Cognitive Radio Prototype Arrives at FCC

A 3/14/07 ex parte filing by the coalition of Dell, Google, HP, Intel, Microsoft and Philips confirms that the long awaited Microsoft-funded prototype cognitive radio has arrive at the FCC Laboratory for testing as part of Docket 04-186.

The coalition claims that this radio will function in the listen-before-talk mode and detect both TV stations and wireless microphones at low enough sensitivities in order to avoid occupied channels for TV band Wi-Fi-like use.

The FCC proposals in this proceeding have been extremely controversial, pitting new economy companies, such as the coalition members, against old economy companies like the TV broadcasters and manufacturers of UHF FM wireless microphones. At stake is providing low cost broadband access in rural America where TV frequencies are especially useful for long range communications in sparsely populated areas. The broadcasters claim the future of "free TV" is at stake.

The docket has accumulated 860 documents to date and no end is in sight.
