The system is designed to provide GSM 900 mobile network coverage (supports HSCSD, GPRS, EDGE) for remote territories, automobile roads, or railways where the installation of common GSM base stations is not feasible due to small mobile traffic.
The system comprises capacity transfer radios (CTR) which retransmit the radio signal sequentially from a base station to users' mobile terminals, and provide network coverage over a territory.
The system is connected to the equipment of a common GSM-site (compatible with the equipment of any vendor), and retransmits and distrubutes up to 6 GSM carriers of a base station (from 1 to 3 hops without radio relay systems) over a target territory.
Converter is to be mounted at the site of a base station. The unit converts carrier frequencies of BTS (up to 6 carriers) to retransmission bandwidth, and then transmits them to a remote area.
Radio (CTR) at the remote area receives, amplifies, and retransmits the signal, and also converts the two signals to GSM bandwidth providing further coverage of 2 sectors similar to a base station (1 GSM carrier in each sector).
