The EMTS Telecom Services LTE Band Selective Mini-Repeater is integral to the LTE network deployment. It extends the coverage by receiving processes and amplifying the RF signal. The single-band LTE-900 MHz is a 20dBm mini- Repeater providing an affordable solution to solve the indoor signal coverage problems in LTE 900MHz systems. Due to signal fading and attenuation caused by architecture obstacles, the signal strength is weak; our mini-Repeater and its easy installation & maintenance can help carriers get a faster return. 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 it, 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. It provides tunable band selective and fix band (factory set) types in two versions. 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).
Key Features
- Fully comply with GSM-LTE standard supports the 900 MHz band
- User-friendly front panel control &plug and play installation- the repeater status can be known during installation
- A smart function can be activated via the front panel, preventing UL interference and self-oscillation and automatically keeping optimal conditions
- Isolation detection function - Auto Isolation check between service and donor antennas to eliminate the self-oscillation. Smart Automatic Level Control (ALC)ensures output level is stable and adjustable continuously
- Low power consumption with an optional sleeping mode (saving power)
- Linear power amplification with an extremely low EVM and an option supporting 5G
- An optional digital module supporting multiple sub-bands, 5,10.20 and 25 per block
- Simple installation with an external AC/DC adapter
- An opportunity for remote monitoring and alarm using a 4G internal modem
