The White Spaces Coalition is a group of companies working together to win FCC approval for use in the United States of devices that use the frequencies in between
DTV broadcasts, the so-called "white spaces" where no channel is being broadcast, for wireless communication. To date, one device tested by the U.S. regulatory agency has failed, causing interference with existing (licensed) frequencies in the process. A second device has been submitted to the FCC, and is currently being tested. Although it's also had problems operating correctly, unlike the first test unit it hasn't interfered with existing broadcasts when it's broken down, and therefore is still being considered by regulators.
Proponents of white space networking claim that it could be used to allow broadband internet connections of up to 80Gbps (80 billion bits per second), or 10GBps (10 billion bytes per second).
Companies in the White Spaces Coalition:
- Dell
- Earthlink
- Google
- Hewlett-Packard
- Intel
- Microsoft
- Philips
- Samsung Electro-Mechanics
Opposition
Opponents say it poses too much risk of interfering with licensed TV broadcasting, and shouldn't get FCC approval. The majority of these concerns are being raised by broadcasters and broadcast industry groups.
