3. MODEL DESCRIPTION Nikrans NS-150GD Dual Band GSM repeater is the answer to poor network coverage. Operating at two frequencies, 900MHz and 1800MHz, it mainly amplifies signal strength for GSM voice calls and 3G connection though it may be efficient for amelioration of 4G signal so long as the latter is transmitted at 1800 MHz in the customer's area. It is compatible with all major carriers in the UK, i.e. -

SPECIFICATION Indoor coverage: 1700 ft² Up-link freq: 880-915MHz & 1710-1785 MHz Down-link freq: 925-960MHz & 1805-1880 MHz Up-link Gain: 60 dB Down-link Gain: 60 dB Power supply: Input AC100~240V,output DC7V/3A Working t °C: -25/+55 Humidity: 5 - 85 % Size (mm): 175*131*33mm Booster Weight:... - Page 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;...

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).

other, it will evoke self-excitation. To fix the problem, you would need to place the outdoor antenna at the largest possible distance from the indoor antenna. 7.4. System Test 7.4.1. Check whether the coverage is good 1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred). To test signal level with a cell phone, make use of its engineering mode (Field Test Mode), which is an application available in free access or a phone mode requiring no extra setups. - 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 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.
