The 2100MHz EMTS Telecom Services Band Selective Mini-Repeater optionally supports LTE & WCDMA and 5G network deployment. It extends the coverage by receiving processes and amplifying the RF signal. The single-band LTE/WCDMA- 2100 MHz is a 20dBm mini-Repeater providing an affordable solution to solve the indoor signal coverage problems in LTE/WCDMA 2100MHz 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. Two versions of tunable band selective and fix band (factory set) types are provided. The band-selective function can choose to amplify the signal within the customized band. The EMTS LTE/WCDMA Micro Repeater is designed explicitly for in-building LTE/WCDMA applications. It supports different LTE/WCDMA channel bandwidths (1.4, 3, 5, 10,15,20MH) and can meet any future LTE/WCDMA and optionally 5G channel allocation need (applicable for tunable band selective type)
Key Features
- Fully comply with LTE/WCDMA (optional 5G) standard at the 2100 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 MHz per block
- Simple installation with an external AC/DC adapter
- Optional for remote monitoring and alarm using a 4G internal modem
