Abstract
In one embodiment, a distributed antenna system comprises at least one master unit; at least one remote antenna unit coupled to the master unit and comprising a power amplifier to radiate a remote downlink radio frequency signal, the remote antenna unit further configured to receive a remote uplink radio frequency signal from at least one antenna, the remote downlink radio frequency signal comprises first and second downlink frequency bands and wherein the remote uplink radio frequency signal comprises first and second uplink frequency bands; a band suppression module comprising: a controller; an uplink band suppression element configured to apply an attenuation to suppress the first uplink frequency band in response to a signal from the controller; and a downlink band suppression element configured to apply an attenuation to suppress the first downlink frequency band in response to the signal from the band suppression controller.
