40dBm Channel Selective High Power Repeater
The EMTS Telecom Services Ltd. High Power channel -selective Repeater (DCSHPR) is designed to provide a cost-effective solution, rather than adding a new Base Transceiver Station (BTS), to improve signal coverage and communication quality in the GSM-R system. Its easy installation and maintenance help carriers get a fast return on investment (ROI). The repeater works as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies it, and then retransmits it via the Service Antenna to the weak/blind coverage area. The EMTS Telecom Services Ltd. Power-Repeaters provide an excellent solution to the problem of poor signal coverage. The Repeaters amplify the signals from mobile phones and base stations and can be used in dead areas where service is poor. 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 dramatically reduces 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.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for Wireless Networks.
