INSTALLATION GUIDE Mobile Signal Repeater Booster for Cell Phone Anytone AT7100 GDW Tri Band GSM, 3G | 900/1800/2100MHz Coverage: 700 m2
Preface This user’s manual describes the installation and maintenance of wide band consumer boosters. Please do read user manual carefully before installing and maintaining repeaters. The information in this manual is subject to change without prior notice. 1. Safety Warnings Users must follow the principles below： Repeater should follow system requirements; assure good grounding and lightning protection.
2. Introduction and Reasons for Weak Cellular Signals Cell Phone Signal Booster is a perfect solution for providing improvement of cellular signal reception inside a house, office, restaurant, VIP Room, apartment, building or shopping mall. Generally cell phones cannot pick up or maintain a strong cellular signal due to one of the two following reasons: 1. Location of the Nearest Base Station – Base stations are used to provide broad coverage.
3. Model Description AT7100 GDW is an AnyTone model of a triband amplifier which boosts mobile signals in large areas up to 700 m2 (7500 ft2) . Due to triband characteristics the device improves the signal at three different frequencies at a time. In particular, the device provides perfect GSM connections at 900 and 1800 MHz frequencies. It also improves signals at 2100 MHz frequency, which is used for 3G data transmission.
4. Specification Indoor coverage: 700 m2 Up-link freq: 890-915MHz, 1710-1785MHz, 1920-1980 MHz Down-link freq: 935-960MHz, 1805-1880MHz, 2110-2170 MHz Up-link Gain: 60 dB Down-link Gain: 65 dB Power supply: AC110-220V±10% o Working t C: -25 - +55 Humidity: 5-95% Size (mm): 135-199-35 Booster Weight: 6.
5. Repeater system overview The picture below shows how simple and fast booster installation is and how effectively it works. A Yaggi or panel antenna (it depends on the booster model and its power), as donor/outdoor antenna, is installed at the top of the roof to pick up good mobile signals from the base station, and sends them through the cable to the booster where the signals get amplified significantly; and then the output signals are distributed throughout the area by the indoor/server antenna.
Optionally: Splitters or couplers: when the building structure is too complicated or there is big loss due to thick walls or other reasons, splitters or couplers shall be used so that more antennas can be installed in separate zones to distribute the signals to each corner of the coverage area.
6. Antennas and Cables Setting Up 6.1. Outdoor antenna installation The repeater’s main function is to improve weak RF signals in an area. The formula is: Input power + Gain= Output power. The signal strength from an outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the correct outdoor antenna location in order to get the best signal.
Installation of a Yaggi antenna as an outdoor antenna 6.2. Cable layout and connector assembly 1. Keep the type, specifications, routing direction, location and curvature radius of cables in compliance with the model requirements. Place cables in correct order, bend them smoothly, and protect the surface from any damage. 2. Place RF cables separately from power cables. Take proper isolation measures if they have to be placed on the same cable racks owing to the site condition restrictions. 3.
Requirements to indoor antenna installation: indoor antenna should be 5 meter distance from an outdoor antenna indoor antenna should be at least 2 meters above the ground indoor antenna should be fixed vertically with the ground.
7. Repeater Installation 7.1. Installation requirements 7.1.1. Installation Location Requirements 1. The repeater shall be installed indoor in a cool, dry and ventilated room without erosive gas or smoke, or on a cool and ventilated wall to ensure excellent heat dissipation. 2. Installation height should be sufficient for RF cable wiring, heat dissipation and maintenance. 3. Independent and stable power supply is necessary. 7.1.2. Power requirement Generally AC 100~264V AC / 50±5Hz power supply is required.
6. Plug the power supply into the Signal Booster input (carefully, to avoid damaging the center pin) and then into a wall outlet. Note: It is recommended to plug all AC power supplies for home electronics into a Surge Protector Power Strip. 7. If the light indicator doesn’t turn on, please see the lights indication instructions. 8. Using multiple Signal Boosters in one installation could cause interference to the base station (except for the In-Line Signal Boosters). 7.2.2. Repeater’s ports description 1.

have not been improved, please check recommendations below again: - Weak input signal leads to low output power. To increase input signal power level, change the direction of the outdoor antenna or its installation position or replace it for an antenna with higher gain.
- Use the roof of the building to enlarge isolation (Please try to place the outdoor antenna and indoor antenna on different floors). - Use some obstacles (Such as walls). 2. The repeater’s power is on but the phone cannot get connected to the network and still can not communicate. Reason 1: There are loose or wrong connections in the repeater system. Solution: Please try to fasten the connections between different parts of the system.
8. FAQ 1. Will booster increase the RF radiation? No, it will decrease instead. Every cell phone irradiates heavily being in zones with poor mobile signal as a cell phone is constantly in searching mode. The danger is your cell phone is about 2cm to your body, which makes its usage rather harmful. And when a booster is installed, it improves the mobile signals in the coverage, and your cell phone stops irradiating strongly, thus it will reduce the RF radiation of the mobile phone tremendously.
