The EMTS Telecom Services Ltd. Tri-Band 900/1800/2100MHz Digital Power Repeaters (DPR) provide an excellent solution to poor signal coverage and are used for coverage extension and building applications. The DPR is designed to support signal coverage for 900/1800/2100MHz bands with up to 5000 sqm. covered area, supporting both LTE and WCDMA technologies. The power repeater has an intelligent algorithm to minimize uplink interference; simultaneously, the isolation detection function allows users to be alerted when the distance between the donor and service antenna is insufficient. The easy-to-install feature highlights the DPR as an excellent signal enhancement solution, improving the LTE/WCDMA coverage and capacity and 5G networks dead areas where service is poor. The EMTS Digital Power Repeater also enhances the mobile network's capacity and data coverage in areas with limited signal strengths. It provides an affordable solution for indoor signal coverage problems due to signal fading and attenuation caused by architectural obstacles. Its easy installation and maintenance can help carriers get a fast return on investment. Setting the sub-bands using advanced digital technology is done via EMTS Mobile App or direct connection via USB cable. The EMTS Telecom Services DPR is based on the latest technology using advanced RF and digital modules that reduce power consumption and increase reliability and MTBF. The DPR can be connected to EMTS NMS via an LTE modem for remote monitoring and control & utilizing advanced IMOP algorithm for preventing oscillations. EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for Wireless Networks,

Key Features

  • Triple Band Digital Repeater supporting 900,1800, 2100MHz bands
