As the Federal Communications Commission is still debating over the approval of free, unlicensed use of the slices of spectrum between television channels, better known as “white spaces,” Google decided to take action.

The search giant launched Free The Airwaves, an advocacy site dedicated to spreading the word about the advantages of using the white spaces. The website also includes a petition, as well as an invitation to bring the issue to the public’s attention by submitting videos through YouTube.

Google is now pushing for the use of the slices of unused spectrum in between television channels that were originally intended to prevent radio waves or adjacent channels from interfering with each other, which make up for three-quarters of the airwaves spectrum.

“This vast public resource could offer a revolution in wireless service of all kinds,” said Google, explaining that “freeing the white spaces represents a vote for the future of the Internet.”

The Federal Communications Commission will decide whether to allow this spectrum for anyone’s use this fall. FCC Chairman Kevin Martin is among the supporters of using the white spaces idea, which he considers would benefit everyone.

Google isn’t the only one pushing for white space use; Microsoft, as well as other companies, such as Intel, HP and Dell, want the same thing. However, broadcasters don’t like the idea that much.

TV broadcasters have presented FCC with their arguments against the use of white spaces earlier this year, when they explained that the device tests have shown that the use of the white spaces interferes with TV broadcasting.

Google, together with other white space supporters, suggested that after February 2009, when analog television will turn into digital television, the spectrum could be used for data services, which would significantly increase data transmission speeds.
