Abstract: Methods, systems, and apparatus, for operation of concurrently coordinated microwave paths in coordinated frequency bands are described. In one aspect, a system includes a plurality of primary sites, each primary site including a transceiver portion configured to transmit to or receive from the transceiver portion of another primary site on a coordinated microwave path on a first frequency; a secondary site, the secondary site located in an optimized area, the secondary site including a transceiver portion, the transceiver portion of the secondary site configured to transmit to the transceiver portion of a primary site on a concurrently coordinated microwave path on the first frequency, where the optimized area is an area where interference caused by the secondary site to other transceivers that operate on a different coordinated microwave path on the first frequency is less than interference caused by a primary site to the other transceivers.
