Just days before the Federal Communications Commission members are scheduled to cast their vote on the plan to enable the unlicensed use of the spectrum between TV channels referred to as “white spaces,” Microsoft lobbies for the plan to be approved.

In a conference call on Monday, Microsoft chief research and strategy officer Craig Mundie explained that there is virtually no risk of interference between the white spaces devices and TV signals, and that this is an opportunity the United States should take. Bill Gates is also a supporter of using the white spaces for Wi-Fi services.

The Federal Communications Commission recently released a report which worried TV broadcasters and other companies opposing the use of the white spaces. The report stated that the devices are very less likely to interfere with other communications.

Microsoft responded immediately after the report was made public, congratulating the FCC for crossing a milestone in the path to establish the final rules of the road for the use of the white space.

On the other hand, the National Association of Broadcasters filed an Emergency Request with the Federal Communications Commission, arguing that the findings of the second round of testing are in fact suggesting that unlicensed devices relying solely on spectrum threaten the viability of TV reception.

The Commission is expected to make a decision on November 4. In the meantime, more and more names get involved on either side of the white spaces plan. Among them, Dolly Parton, who sent an open letter to FCC, asking them for more time to review it: “the importance of clear, consistent wireless microphone technology cannot be overstated.”
