Radio with antenna array and multiple rf bands

Abstract

A fixed wireless access radio is disclosed that is compact, light and low power for street level mounting, operates at 100 Mb/s or higher at ranges of 300 m or longer in obstructed LOS conditions with low latencies of 5 ms or less, can support PTP and PMP topologies, uses radio spectrum resources efficiently and does not require precise physical antenna alignment.

What is claimed is: 
     
         1 . A fixed wireless access radio for exchanging one or more data interface streams with one or more other fixed wireless access radios, said radio comprising:
 a plurality of receive radio frequency (RF) chains;   a plurality of transmit radio frequency (RF) chains; and   a plurality of antenna elements, wherein at least a first subset of the plurality of antenna elements is configured to operate over at least both of a first transmit frequency band and a first receive frequency band and each antenna element of the first subset of the plurality of antenna elements is coupled or couplable to at least one of a first subset of the plurality of receive RF chains or coupled or couplable to at least one of a first subset of the plurality of transmit RF chains, and wherein at least a second subset of the plurality of antenna elements is configured to operate over at least both of a second transmit frequency band and a second receive frequency band and each antenna element of the second subset of the plurality of antenna elements is coupled or couplable to at least one of a second subset of the plurality of receive RF chains or coupled or couplable to at least one of a second subset of the plurality of transmit RF chains;   wherein the radio is configured to provide a base throughput capability using the first receive frequency band and the first transmit frequency band.
