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. -

Installation of a panel antenna as an outdoor antenna Installation of Yagi wide band antenna as an outdoor antenna Installation of a Yaggi antenna as an outdoor antenna Cable layout and connector assembly 1. 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). Requirements to indoor antenna installation: •...

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.

7.3. Repeater Settings 7.3.1. Indicator Light Instructions Introduction screen. The introductory page is displayed at the screen for 10 sec during the system check- When the device completes the internal self test, it shows the standby screen. If the arrow down is displayed at the bottom right corner, the device has detected signal reception problems. - Page 15 (on a pole on the rooftop) and pointing it towards the provider's nearest base station. 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.

Page 16: Questions & Solutions
Questions & Solutions If the device detects that the incoming signal is weak, try 3 possible solutions: • Solution 1. Direct the outdoor antenna to provider’s nearest base station. • Solution 2. Change the position of the outdoor antenna. Try to put it as high as possible. •... - Page 17 If the system shows “Device was damaged” note, it means that the uplink/downlink was damaged. Contact customer service for repair. What signal level in dBm is optimal for the correct booster functioning? For the optimal functioning of the booster, the BS (input) readings should be between - 65 and 50 dBm. The MS (output power) readings must be between +05 and +15 dBm.

Yes, you can use only 1 indoor antenna if the distance between both indoor antennas in your case cannot exceed 5m. However, if you can install the indoor antennas at the distance exceeding 5m or create some obstacles like walls between them, we recommend you using 2 indoor antennas for more effective signal distribution and larger coverage. - Page 19 For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get. • -105 to -100 = Bad/drop call •...
- Page 20 - 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. Reason 2: The signals received by outdoor antenna of other operators nearby are too strong.
- Page 21 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.
