1. A method for routing and switching signals comprising:

  • providing a plurality of remote radio units, each remote radio unit configured to transmit one or more downlink signals and to receive one or more uplink signals;

    providing at least one digital access unit configured to communicate with the plurality of remote radio units;

    translating the uplink and downlink signals between RF and base band;

    packetizing the uplink and downlink base band signals, wherein the packetized signals correspond to a plurality of carriers, each remote radio unit configured to receive or transmit a respective subset of the plurality of carriers;

    routing and switching the packetized signals among the plurality of remote radio units via the at least one digital access unit;

    reconfiguring at least one of the plurality of remote radio units by increasing or decreasing the number of carriers in the respective subset of the plurality of carriers; and

    thereafterrouting and switching the packetized signals among the plurality of remote radio units via the at least one digital access unit according to a result of the reconfiguring.
