1. A communication system comprising:
a host unit;
at least one first remote unit coupled to the host unit and operable to direct radio resources to configure to use various carriers in a first cell, wherein the at least one first remote unit is configured to communicate using a first frequency band over a first geographic region corresponding to a portion of the first cell, wherein the at least one first remote unit is configured to communicate using a second frequency band over a second geographic region corresponding to an entirety of the first cell, and wherein the first frequency band is distinct from the second frequency band; and
at least one second remote unit coupled to the host unit and operable to transmit and receive RF communications in a second cell, wherein the at least one second remote unit is configured to communicate using a third frequency band over a third geographic region corresponding to a portion of the second cell, wherein the at least one second remote unit is configured to communicate using a fourth frequency band over a fourth geographic region corresponding to an entirety of the second cell, and wherein the third frequency band is distinct from the fourth frequency band.
