GSM-R / LTE-R High Selectivity p Repeater
The EMTS Telecom Services Ltd. Off the Power-Repeaters provides a solution for DAS, The Repeaters amplify the signals from DAS and base stations. The repeaters support GSM-R and LTE-R and used extensively for railway communication both in Europe and Asia. Our repeaters are deployed to provide coverage within trains, tunnels and other confined spaces. Our repeater produces are easily configured either locally or remotely via a remote or a local , the products supplied in a weatherproof IP66 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 GSM-R and LTE BTS’s and the fiber master unit. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then deliver the singles to the master unit it via RF connection, from the master unit it transmit the RF signals to the BTS via high power amplification unit .
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless
