Expanding Wireless Communications With "White Spaces"

Download Now Free registration required

Executive Summary

Valuable White Spaces spectrum in the underused broadcast TV channels is freed up by the DTV transition in the U.S. This spectrum can be used to expand the bandwidth available for wireless communications. Using the White Spaces requires coexistence technologies to ensure that incumbent users such as TV broadcasts, wireless microphones, and medical telemetry devices are not inadvertently subjected to interference. With strong advances in radio technology, engineering solutions to the coexistence challenge are within sight. The IT and consumer electronics industries, including Dell, are working with the FCC to develop and test these coexistence technologies and bring them to market when they are proven and mature.
