Abstract

During a communication session, a filter in the RAN may filter signals sent over the communication pathway. When the filter filters signals sent over communication pathway, it may also cause some filter loss in the signals. The amount of the filter loss may vary as a function of frequency. Before the start of a communication session, the RAN may determine a filter loss for a given frequency. Because a higher filter loss indicates the RAN will transmit (or receive) a weaker signal, it may be undesirable to transmit signals to WCDs that are located a far distance from the RAN with frequencies having high filter losses. Thus, once the RAN has determined a filter loss for a given frequency, the RAN may reserve the given frequency for use in communication between the RAN and at least one WCD based on a distance between the WCD and the RAN.
