A network is provided that includes a plurality of antennas coupled over
the network to a plurality of base stations. The network can be optical
or constructed with RF microwave links. The base stations are configured
to provide cellular transmission. A plurality of links couple the
plurality of antennas and the plurality of base stations. At least one
link of the plurality of links provides multiple transmission paths
between at least a portion of the base stations with at least a portion
of the antennas. In one implementation, at least one link of the
plurality of links is shared by at least two cellular operators on
different transmission paths. In another implementation, at least a
portion of the plurality of base stations are in a common location and at
least a portion of the antennas are geographically disbursed.
