Embodiment Construction

[0015] figure 1 is a block diagram of one embodiment of a communication network 100 . exist figure 1 In the illustrated embodiment, the communication network 100 includes a base station 102 communicatively coupled to a distributed antenna system (DAS) 103 . In other embodiments, DAS 103 is used to communicate between one or more upstream devices (such as base transceiver stations 102, wireless access points, or other sources of radio frequency signals) and one or more downstream devices (such as wireless terminals) 112) to transmit radio frequency signals between. In some embodiments, base transceiver station 102 (also referred to herein as a "base station" 102) is part of a telecommunications service provider's infrastructure and wireless terminals 112 comprise customer premises equipment. In general, for each radio frequency signal or channel over which base station 102 communicates with downstream wireless terminals 112, an original downlink radio frequency signal is ini...

Abstract

The present invention provides a method of switching a communication device between an uplink communication path and a downlink communication path. The method measures a power level of a signal on at least one radio frequency for one of the uplink communication path and the downlink communication path. The measured power level is compared to a threshold power level. Switching between the uplink circuit and the downlink circuit is based on a comparison between the measured power level and the threshold power level.
