The EMTS Telecom Services Dual-Band LTE Digital Mini Repeaters (DMR) provides an excellent solution to the problem of poor signal coverage and is used for coverage extension and in-building applications. The DMR is designed to support signal coverage for three bands: 900MHz and 2100MHz, with up to 2000 sqm covered area. The mini repeater uses an intelligent algorithm to minimize possible uplink interference. It supports multi-operator installations utilizing an advanced digital software-defined filter. The EMTS Digital Mini Repeater isolation detection function allows users to set a suitable distance between donor and service antennas. The easy-to-install feature highlights the DMR as an excellent signal enhancement solution, improving the LTE network's coverage and capacity in dead areas where service is poor or not existing while allowing the operator a fast return on investment.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless Networks.
