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.
Ask a question Coverage area The NS-600FLG booster has a surface area of 600 m² (about 6400 ft²). This model is suitable for large buildings, such as big offices, restaurants, large shops and shopping centres, hospitals, parking lots, and so on.
SPECIFICATION Indoor coverage: 600 m² Up-link freq: 703-733, 832-862, 880-915 MHz MHz Down-link freq: 758-788, 791-821, 925-960 MHz MHz Up-link Gain: 65 dB Down-link Gain: 65 dB Power Output: Input AC90~264V, output DC5V/2A Energy Consumption: 0.007 kW/h Working t °C: -25/+55 Humidity: 5 - 95%...

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;...
ANTENNAS AND CABLES SETTING UP 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 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.

Lightning Surge Protector Setup Please read carefully the instructions provided with the coaxial surge protector to ensure safe and effective installation in terms of grounding and maintenance. 1. Connect the male N-connector of the surge protector to the female N-connector of the outdoor antenna. 2.
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).
REPEATER INSTALLATION Installation requirements 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.

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. Plug in the indoor antenna to the mobile booster from MS side and fasten tightly. 4.
Repeater’s ports description 1. Outdoor port: connected with the outdoor antenna by cable 2. Indoor port: connected with indoor antenna directly or by cable 3. DC IN: connected with power supply. Accessories selection Choosing accessories pay attention to the two characteristics – frequency and impedance. All accessories shall support the repeater’s frequencies.

Five Band repeater display and operation interface The booster is a 5 band device that supports 5 different kinds of signal: LTE 800, GSM 900, DCS 1800, WCDMA 2100, LTE 2600. 1. The1 line shows the output signal strength. 5 bars appearing next to the signal strength indicator signify the maximum output power of the repeater.
Page 16
LED indicator status and definition In order to maintain required output signal levels, this repeater has in-built signal oscillation detection circuit to adjust the gain automatically so as to avoid interference to the operators’ cellular network. When the “Smart” function is enabled, the repeater sets up the suitable gain automatically thus not causing any interference to the mobile network.

Status ALARM It is working in linearity Green Note: Input signals may be not enough, please pay attention to the readings displayed by the device. Do not do anything if it is good; otherwise please adjust the repeater system to get better source signal. It is working with slight oscillation.
Questions & Solutions 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. Device Gain must be 65/65 dB. If the BS is lower than - 65dBm, the coverage will be smaller.

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 •...

Remark: • Reduce attenuation values * — by ensuring the isolation level • Increase output power * — recommended ways: to adjust outdoor antenna direction/location, or replace it to an antenna with higher gain to increase input signal strength. Repeater can not communicate in Power-ON status 1.

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.
