ABSTRACT:
Microcellular low power wireless networks for interactive, full duplex communication of video, data and telephony signals at microwave frequencies. Networks according to the present invention link a number of remote node transceivers to a central head office via fiber optic link. The remote node transceivers convert optical signals to radiofrequency energy in the microwave (preferably MMDS) range for robust and reliable communications that can, among other things, support basic lifeline telephone service. Low power and cross polarization techniques according to the present invention, together with modulation and multiplexing techniques, allow the limited bandwidth allotted in conventional microwave bands to accommodate analog and digital video, video on demand, data communications including graphics-rich internet traffic, and voice and digital telephony, in a full duplex, bi-directional fashion.
