Abstract
Abstract A broadband radio access method device and system includes a first wireless communication segment that operates under 10 GHz, and a second wireless communication segment that operates over 20 GHz. Coordination between the first segment and second segment occurs when establishing links with a subscriber, such that the broader band services available from the second communication link, are assigned to the subscriber, when the communications channel is available to support line-of-sight communications with the subscriber. When the communications channel does not support the second communication segment, the subscriber is assigned to operate with the first communication segment. An integrated first and second segment terminal is provided to provide a transmodulation device for converting signaling protocols between the two different segments so as to support communications between the subscriber and the intended recipient even if the two use apparently incompatible signaling protocols.
