The EMTS Telecom Services Ltd. GSM-R Band Selective Power Repeater provides an affordable solution to solve the indoor signal coverage problems in the GSM-R systems due to signal fading and attenuation caused by architecture obstacles. GSM-R systems are used extensively for railway communication both in Europe and Asia. Our GSM-R repeaters are deployed to provide coverage within trains, tunnels, and other confined spaces. Our GSM-R products are easily configured either locally or remotely via a remote or a local, the products are supplied in weatherproof IP65 cases. This combination of repeaters permits to reduce dramatically the number of BTS, and then, the total cost of deployment, for a better Quality of Service. The benefits are double: better QoS and better total cost. The repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal, and then retransmits it via the Service Antenna to the weak/blind coverage area.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless Networks.
