US08706165B2 Method and apparatus for reducing combiner loss in a multi-sector, omni-base station

Because the antenna unit signals combined are at different frequencies, they do not interfere as much as they would if they were at the same antenna frequency, which results in less signal loss and degradation in the combiner. The carrier signals are then restored in the base station transceiver from the different respective frequencies to intermediate frequency for further processing.

Consistent with the present disclosure, client data, which may include multiplexed data sub-streams, is supplied to an ingress node of a network. Each sub-stream typically has a corresponding data rate, i.e., an original data rate, prior to multiplexing. The client data is encapsulated in a plurality of successive frames that are output from the ingress node and propagate, typically through one or more intermediate nodes, to an egress node.
