Google will be conducting a 45-day public trial with the FCC to create a centralized database containing information on free spectrum. The Google Spectrum Database will analyze TV white spaces, which are unused spectrum between TV stations, that can open many doors for possible wireless spectrum expansion in the future. By unlocking these white spaces, wireless providers will be able to provide more coverage in places that need it.
The public trial brings Google one step closer to becoming a certified database administrator for white spaces. Currently the only database administrators are Spectrum Bridge, Inc. and Telcordia Technologies, Inc. Many other companies are applying to be certified, including a big dog like Microsoft. With companies like Google and Microsoft becoming certified, discovery of white spaces should increase monumentally.
Google’s trial allows all industry stakeholders, including broadcasters, cable, wireless microphone users, and licensed spectrum holders, to provide feedback to the Google Spectrum Database. It also allows anyone to track how much TV white space is available in their given area. This entire process is known as dynamic spectrum sharing.
Google’s trial, as well as the collective help of all the other spectrum data administrators, will help unlock more wireless spectrum. It’s a necessity as there is an increasing number of people who are wirelessly connecting to the internet via smartphones, laptops, tablets, and other wireless devices. This trial will open new doors to more wireless coverage (especially in dead zones), Wi-Fi hotspots, and other “wireless technologies”.
