2. Introduction 2. Introduction 2.1. Purpose Mobile telephone and public safety systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area to carry voice and data traffic. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distributed antenna system (DAS).
