FCC chooses nine firms to oversee spectrum white-space database

A database of open channels, or "white spaces," opening on the television spectrum for use by unlicensed devices, will be managed by nine companies, Television Broadcast reports today (Jan. 27). The companies, selected by the FCC, will oversee a database that will track white spaces within the TV spectrum and communicate those channels to unlicensed devices. It will be the sole source of interference protection for TV signals and wireless microphones, the industry publication said.
