ABSTRACT:
A communication system includes a high data capacity microwave link in the millimeter band. A defined frequency band is segmented allowing for direct video transmission in a first segment while at the same time achieving full duplex operation within a second segment. The system provides a wide variety of data and video services including two-way video communication and data transfer, direct broadcast video, video teleconferencing, video library access and telephony. A subscriber transmits a request for custom video, a real-time two-way data link, or a non-real time asymmetrical data download. The hub allocates the appropriate bandwidth necessary for the service and assigns a carrier frequency and time-slot to the subscriber. The hub retrieves the appropriate video or data and transmits it to the subscriber, or establishes a data link between the subscriber and a data network.
