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;...

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. -

Keep the type, specifications, routing direction, location and curvature radius of cables in compliance with the model requirements. - Page 10 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 Installation with 2 indoor antennas INSTALLATION STEPS 1. Find an appropriate position for an outdoor antenna. ( see the r equirements in 6.1. sect. ) 2. Plug in the outdoor antenna to the mobile booster from BS side and fasten tightly. 3.
- Page 13 5. Don’t put the antennas (outdoor and indoor) too close to each other. Recommended distance is 10-20 m. Be sure to point them to the opposite directions to avoid the risks of malfunctions such as self-oscillation or interference. It's also recommended that they are not placed in direct vision to each other (use metallic obstacles, wall, ceiling, slab, etc).

If the BS is higher than - 50 dBm, the device will have self-excitation issue. In such cases, the output signal will drop during communication. If the antennas are placed very close to each other, it will evoke self-excitation. To fix the problem, you would need to place the outdoor antenna at thelargest possible distance from the indoor antenna. - Page 16 If the device detects that the outdoor antenna is too close to the indoor, change the position of either or both antennas to avoid self-oscillation. Mount them at least 15m one from another. If the device detects self-oscillation between the antennas and says that the system is being adjusted, it means that the system has detected the problem of bad isolation between the antennas and AGC is adjusting the system gain automatically to make the device work correctly.

In case of installation errors an exclamation point/arrow appears on the LCD screen. It happens in two cases: 1. Input signals (external BS) are weak. It can happen that even with a weak signal the amplifier works well. In this case, nothing should be done. Just ignore a flashing exclamation point. - Page 18 the outdoor antenna or its installation position or replace it for an antenna with higher gain. - Check whether it is necessary to use additional indoor antennas as barriers block signal penetration; also check whether the repeater’s power is enough; please install extra indoor antennas or replace the repeater for another model with higher power level.
- Page 19 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 20 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.
