Product Description

TETRA 400MGHz ICS Repeater
Model: BT-7A40S
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/DCS/PCS 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.

Features

  
 

Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
No interference to BTS by adopting linear amplifier with high gain and low noise
Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater

Applications

 
 
To expand signal coverage or fill signal blind area where  signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …

Installation & Commissioning

1.1 Installation

  1. At the installation site, install the repeater as per specified plan and site layout. The repeater can be wall-mounted or pole-mounted using the brackets as shown below.

 2. Connect the repeater to the grounding board.
 3. Install the Donor Antenna and Coverage Antenna as per the specified plan and site layout.
 4. Use Site Master to measure the VSWR of the RF cables from the Donor Antenna and         Coverage Antenna. The value should be less than 1.5; Otherwise, check the connectors       and the installation of the cable.
 5. Connect the power supply (and backup power if required) to the repeater.
 6. Start commissioning the repeater.

 1.2 Commissioning

  1. Connect the RF cable from Donor Antenna to the spectrum analyzer and check if the Donor Antenna is receiving the correct frequency; and then measure the signal level of the said frequency (RSL). Adjust the antenna to make the readings approach the recorded value on the survey report. Record all readings.
  2. Inside the repeater, disconnect the uplink duplexer to the ICS module so as to cut any signal coming from air going to the uplink duplexer and thus protecting the amplifier from damaging. Connect a 30 dB attenuator to the output of the repeater; this attenuator will serve as a load for the repeater. The purpose of this attenuator is to protect the equipments from damaging.
  3. Turn ON the repeater. Observe the LED display on the NMS board. Check for any alarm. Under normal condition, the POWER LED should be always green and the RUN LED should be blinking, the ALARM LED should be not bright with red color.
