1. A wireless repeater for receiving, amplifying and transmitting one or more wireless signals comprising:
a signal processing device for determining one or more attributes of a wireless signal received from a base transceiver station;
a memory for storing a reference list that includes a list of one or more preferred frequency bandwidths to be amplified and transmitted;
a controller coupled with the signal processing device for comparing the one or more attributes of the wireless signal from the base transceiver station with the reference list, wherein the controller selects a first active set of one or more frequency bandwidths from the preferred frequency bandwidths based on the comparison;
a first reception filter coupled with the controller, wherein the first reception filter, responsive to one or more control signals from the controller, filters out signals, communicated to the first reception filter, having frequencies not within the first active set of frequency bandwidths;
a first antenna coupled with the signal processing device for receiving the wireless signal from the base transceiver station;
a second antenna for receiving wireless signals from a mobile device; and
a second reception filter coupled with the second antenna and the controller, wherein the second reception filter, responsive to control signals from the controller, filters out signals, received with the second antenna, having frequencies not within a second active set of frequency bandwidths, wherein the second active set of frequency bandwidths is determined based on the comparison of the one or more attributes of the wireless signal from the base transceiver station with the reference list.
