The EMTS Telecom Services LTE Band Selective Mini-Repeater is an integral part of the LTE network deployment. It extends the coverage by receiving processes and amplifying the RF signal. The single-band LTE-1700 MHz is 20dBm mini- Repeater providing an affordable solution to solve the indoor signal coverage problems in LTE 1700MHz systems. In many case, due to signal fading and attenuation caused by architecture obstacles, the signal strength is weak. The EMTS mini- repeater and its easy installation & maintenance can help carriers get a faster return on investment. The repeater works as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the donor antenna, linearly amplifies the signal, and then retransmits it via the indoor signal distribution system to the weak/blind coverage area. The mobile signal is also amplified and retransmitted to the BTS in the opposite direction. The repeater can be provided in two versions, tunable band selective and fix band (factory set) types. The band-selective function can choose to amplify the signal within the customized band. The EMTS LTE Pico Repeater is designed explicitly for in-building LTE applications. It supports different LTE channel bandwidths (1.4, 3, 5, 10, 15 & 20MHz) and can meet any future LTE channel allocation need.
interference and oscillation problems, challenging coverage holes, rapid response deployment, and inadequate in-building coverage. Regardless of the technology or frequency, EMTS can provide customized coverage solutions that address any combination of unique and complex network needs for Wireless Networks.
Key Features
