TVWS supporters such as Google contend the unlicensed spectrum is suitable for bringing cost-effective broadband service to rural and remote areas in the United States and around the world. The FCC has authorized use of five spectrum blocks for TVWS operations: 54 to 60 MHz, TV channel 2; 76 to 88 MHz, TV channels 5 and 6; 174 to 216 MHz, TV channels 7 to 13; 470 to 608 MHz, TV channels 14 to 36; and 614 to 698 MHz, TV channels 38 to 51. Database systems such as Google's, which provides a list of available TVWS channels, are necessary to support unlicensed radio devices transmitting in the spectrum bands used by broadcast television. In order to avoid creating interference, TV band devices (TVBDs) must contact an authorized database system to obtain a list of channels that are available at their individual locations and operate only on those channels.
