Band 3 1800MHz 20dBm Band Selective Mini Repeater
The EMTS Telecom Services GSM/LTE/5G Band Selective Mini-Repeater is integral to the GSM/LTE/5G network deployment. It extends the coverage by receiving processes and amplifying the RF signal. The single-band LTE/5G 1800 MHz is a 20dBm mini-Repeater providing an affordable solution to indoor signal coverage problems in GSM/LTE/5G 1800MHz 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 two versions of tunable band selective and fixed band (factory set) types. The band-selective function can choose to amplify the signal within the customized band.
Key Features
- Fully comply with GSM and LTE meets CE, ETSI, and 3GPP standards
- 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 using IMOP – Isolation Measurement Oscillation Preventing
- Isolation detection function – Auto Isolation check between service and donor antennas to eliminate with an optional for ICS, 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,5,10,20,25MHz per block
- Simple installation with an external AC/DC adapter
- Remote monitoring and alarm using a 4G internal modem using EMTS cloud NMS enable getting status and warnings to any desktop or mobile phone using Web GUI
