SCALABLE WLAN WIRELESS COMMUNICATIONS DEVICE AND RADIO FOR WPAN AND WRAN OPERATION

摘要

An apparatus and method for wireless devices have a scalable bandwidth allocation for operating in different bands at different data rates and provide interference prevention between co-existing modes of operation. MAC frame logic selectively defines first characteristics of a first operational mode corresponding to a first wireless link type and second characteristics of a second operational mode corresponding to a second wireless link type. Interference detecting logic detects interference conditions in the first wireless link type and allocates suitable areas for operation of the second wireless link. The same principle used in scaling WLAN to WPAN operation, can also be applied at the lower bit rate of WRAN, in which case a larger range is achieved using a narrower bandwidth and lower a clock rate.
