On Monday, Google sent a letter to the Federal Communications Commission (FCC) urging the Commission to open up vacant TV airwaves, known as white spaces, for use with mobile devices.

In the letter, Google suggested ways that the white spaces could provide high-speed wireless access to consumers without affecting TVs or wireless microphones.

Google is a huge advocate of open access and a member of the Open Handset Alliance. The alliance’s goal is to foster innovation on mobile devices and give consumers a better user experience through open standards.

In July, Google announced its intention to participate in the auction of spectrum in the 700 MHz band if the FCC adopted a framework requiring greater competition and consumer choice. Google urged the Commission to adopt four open platforms as part of the license conditions: open applications, devices, services and networks. The FCC decided to support two: open applications and devices.

And at the close of the auction last week, Google scored a victory when Verizon spent $4.7 billion on spectrum, which will be available for any legal device. Bids had to be more than $4.6 billion to trigger the open-access rules.
