1. A method for routing and switching operator RF signals, the method comprising:

  • providing a plurality of Digital Remote Units (DRUs), each configured to receive one or more downlink radio frequencies and to transmit one or more uplink radio frequencies; and

    providing at least one Digital Access Unit (DAU) configured to communicate with at least one of the plurality of DRUs,wherein a first DRU in a first cell is operable to communicate using a first set of frequencies characterized by a first frequency band over a first geographic footprint,wherein a plurality of second DRUs in the first cell are operable to communicate using a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint surrounding the first geographic footprint,wherein a third DRU in a second cell is operable to communicate using the first set of frequencies over a third geographic footprint, andwherein a plurality of fourth DRUs in the second cell are operable to communicate using a third set of frequencies characterized by a third frequency band different from the first frequency band over a fourth geographical footprint surrounding the third geographical footprint.
