usage types: broadband services to homes and businesses at a higher power level tofixed devices over larger geographical areas; and wireless portable devices at a lowpowerlevel in indoor environments.To prevent interference with TV transmissions, both device types must employ geolocationcapability with 50-meter accuracy (although fixed devices can store their positionduring installation), as well as having the ability to access a database that lists permittedchannels for a specific location. In addition, all devices must be able to sense thespectrum to detect both TV broadcasting and wireless microphone signals. The rulesinclude transmit power limits and emission limits.The frequency-sensing and channel-change requirements are not supported by today’s3GPP, 3GPP2 and WiMAX technologies. The IEEE, however, has developed a standard,IEEE 802.22, based on IEEE 802.16 concepts, that complies with the FCC requirements.IEEE 802.22 is aimed at fixed or nomadic services such as DSL replacement.The industry is in the very early stages of determining the viability of using white-spacespectrum and, at this time, there are no products or services available.Transition to 4G: 3GPP Broadband Evolution to IMT-Advanced, Rysavy Research/3G Americas, Aug 2010 Page 120
