Product Description
Specifications of GSM850 ICS Pico Repeater

Model: BT-GA15S-4

The  ICS Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in GSM system. And its easy installation and maintenance can help carriers get fast return.
The repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the coverage antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

GSM 850MHz Ics Pico Repeater


  • Built-in coverage antenna facilitates the installation
  • Highly selective digital channel selector can process 4 channels simultaneously
  • Real Time Interference Signal Cancellation (Multi-path Fading, Feed-Back signal) greatly reduces system isolation requirement
  • Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
  • Simple installation with external AC/DC adapter


To expand signal coverage or fill signal blind area where WCDMA signal is weak or unavailable.
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots,  …

View of Repeater

PANEL View of Repeater 
  1. It supports vertical mounting installation, follow the instructions below.

GSM 850MHz Ics Pico Repeater
  1. First of all, choose a mounting position for the Pico Repeater in indoor environment, the mounting base is flat in horizontal plane; it can be placed on the windowsill vertically.
  2. LCD screen side must face the open area of coverage area.
  3. Built-in door antenna and coverage antenna
  4. Equipment is supplied by AC220V power via connection of the external extension power cable.
  5. USB port is used for Local setup.
  6. GSM system can automatically search frequency (Channel No) and it needs 3-5 minute to complete; WCDMA systems need manual set as required.
