Page 3: Introduction And Reasons For Weak Cellular Signals
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. -
Page 4: Model Description
3. Model Description Mobile signal booster MA-130 is a GSM model which amplifies cell phone voice communication quality in the EU, Asia and most other countries of the world. The repeater functions at 900 MHz frequency used for GSM signal transmission (voice calls) and Edge/Gprs Internet connection. Some european providers also use 900 MHz frequency for 3G Internet connection. -

Page 6: Repeater System Overview
5. Repeater system overview A repeater kit includes: • Outdoor Antenna? Outdoor panel or wide band Yaggi is recommended. Function: To pick up outside signals from the base station and send them by cable to the repeater; outdoor antenna also transmits the uplink signals from the repeater back to the base station. - Page 7 • Additional indoor antennas: when the building structure is too complicated...

Page 8: Antennas And Cables Setting Up
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. - Page 9 If isolation can’t be achieved due to limited distance, the roof of the building, walls or any other barriers can be used between antennas to increase isolation. Installation of a panel antenna as an outdoor antenna Installation of a wide directional antenna as an outdoor antenna Installation of a Yaggi antenna as an outdoor antenna 6.2.
- Page 10 6.3. Indoor antenna installation Correct antennas types shall be used according to the site conditions and the requirement. 1. Omni antenna (ceiling Omni or whip antenna) shall be installed in the center and radiate all directions. 2. It is better to use a directional panel antenna or Yaggi antenna when the area shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space).

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. - Page 12 3. In order to prevent water from coming into the mobile phone booster through the cable make a loop in it. 4. Keep the outdoor antenna as far as possible from frequency aerials, high voltage cables, metal nets or transformers. 5.
- Page 13 7.3. Repeater Settings 7.3.1. Indicator Light Instructions • The equipment works correctly when power LED indicator light P is on, any other status means power failure or equipment failure. • The equipment works correctly when both Up-link indicator light U and down-link indicator light D are on.
- Page 14 If the signals in most areas 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.
- Page 15 7.4.2. Repeater can not communicate in Power-ON status 1. The power is on but there is a signal fluctuation or a flash signal. The phone call cannot be made/received. It shall be caused by the insufficient isolation between outdoor and indoor antennas. Please take the following measures: - Firstly check whether the alarm LED lights.
- Page 16 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.
