FAQs

  1. What is “white space” spectrum?

    • “White spaces” are unused spectrum between licensed broadcast channels in the 150MHz to 700MHz spectrum bands.
  2. Who is opposing the use of “white space” spectrum?

    • The National Association of Broadcasters (NAB) and other broadcasters, such as ABC, CBS, NBC, and Fox.
  3. Why is the NAB opposing the use of “white space” spectrum?

    • They claim that wireless devices using this spectrum will cause interference in the neighboring spectrum bands.
  4. What does the FCC report say about interference from “white space” devices?

    • The FCC’s Office of Engineering Technology report states that devices with geolocation and sensing technologies could be used without interference.
  5. Who is lobbying the FCC to open up “white space” spectrum?

    • Several technology companies, including Motorola, Microsoft, and Google.
  6. What do technology companies believe “white space” spectrum can be used for?

    • To enhance or create new wireless broadband services, such as data transmission over long distances and through walls.
  7. What is the FCC’s proposal regarding “white space” spectrum?

    • FCC Chairman Kevin Martin will submit a proposal to the commissioners to vote on, which would open up white spaces for unlicensed use.
  8. What is the date of the FCC vote on “white space” spectrum?

    • November 4th, 2008.
  9. What is the potential spectral capacity of “white space” spectrum?

    • Between 300MHz and 400MHz of unlicensed spectral capacity.
  10. What is the ideal use case for “white space” spectrum?

    • Wireless data transmission over long distances and through walls.
  11. What are the key technologies to prevent interference from “white space” devices?

    • Geolocation and sensing technologies.
  12. What is the next step in the “white space” spectrum debate?

    • The FCC’s vote on Chairman Martin’s proposal on November 4th.

Summary

The FCC is considering opening up “white space” spectrum for unlicensed use, which has sparked a debate between broadcasters and technology companies. The NAB and other broadcasters argue that white space devices will cause interference, while technology companies claim they can develop products that won’t interfere. The FCC’s report supports using white space with geolocation and sensing technologies, and Chairman Martin will put forward a proposal for a vote on November 4th. This spectrum has the potential to provide between 300MHz and 400MHz of unlicensed spectral capacity nationwide, which could lead to new wireless broadband services.
