Product Description

40dBm GSM 900MHz Ics Cellphone Booster /Cellphone Signal Amplifier (GW-40-ICSG)

The Tetra UHF VHF Signal Booster, It has a simple structure to transparently convey and amplify the wireless signal (at the same frequency) between the BTS (Base Transceiver Station) and mobiles in a Dual wireless network, it picks up the signal from the BTS via the Donor Antenna, linearly amplifies the signal, and then retransmits it via the Coverage Antenna (or the Indoor Signal Distribution System) to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Product Description

Working Principle:
When the repeat antenna receives uplink signals from a subscriber, the signals will undergo the processing of a low-noise amplifier, filter, and power amplifier first, and then be transmitted to the base station, thus accomplishing the connection between subscribers in the signal blind area and base station.
In this way, the blind areas are eliminated.
Considering receiving signal intensity and coverage size may vary with sites where the repeater is located, it is necessary to control the gain and output of the repeater.
Additionally, considering the fading effect in spatial signal transmission, auto amplitude fixing for output is required.
For this purpose, MGC and ALC circuits are included in the uplink/downlink channels.

I.Features:

1. Aluminum-alloy casing with IP65 protection has a high resistance to dust, water, and corroding
2. Low interference to BTS by adopting a linear amplifier with high gain and low noise
3. Adopting filter with high selectivity and low insertion loss eliminates interference between uplink and downlink
4. The USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise the repeater's working status and download operational parameters to the repeater.

Installation Instructions

I.Site Survey before Installation

Before you install, the installer should contact the person responsible for the project, understand whether there are installed conditions in the installation site.

Specifically include Installation site, surroundings (Temperature and Humidity), power supply, and so on.
If qualified should go live on-site survey with related personnel. The repeater is designed that can working outdoors, operating temperature is -25ºC~65ºC, humidity is ≤95%, which can be adapted to most areas of the natural environment.

II.Recommended Environmental Requirements:

1.Installation area non-corrosive gases and fumes, Electromagnetic interference field strength ≤140dBμV/m(0.01MHz~110000MHz).
2.Mounting height should facilitate RF cable routing, cooling, safety, and maintenance.
3.Should provide a set of independent and stable 150VAC~290VAC(Nominal 220V/50Hz)AC Power. It must not be shared with other high-power appliances telecommunications equipment.
4.Lightning protection devices must be installed in the building, and it should have sufficient strength and stability.
5.There are grounding bar in the vicinity.

III.Installation Tools

Installation tool to use: Electric impact drill, iron hammer, pulleys, ropes, belts, helmets, ladders, screwdriver, hacksaw, knife, pliers, wrenches, compass, measuring tape, tweezers, electric iron, portable PC, 30dB directional coupler, spectrum analyzers, VSWR tester.

IV.Repeater installation

It can be a holding pole or wall mounting way. It should be installed in a ventilated place, vertically on a wall or mast to ensure good heat dissipation, if hanging on the wall, the upper part of the equipment to be considered more than 50cm from the ceiling, the lower part of the equipment needs more than 100cm from the floor.
 

V.Safety Instruction

   V.I.Antenna and Feeder Installation and Precautions

        1.Installation of antenna systems requires experienced professionals to complete.
        2.You can not install an antenna near power lines, which may be life-threatening.
        3.All exposed joints must use self-adhesive waterproof tape and electrical insulation tape seal securely.
    VII.Connect the Ground and Power Supply
        1. Equipment Grounding
            The equipment must be well grounded, there is a copper on the repeater wall chassis ground, use 4mm2 or thicker copper wire close to              the ground. Grounding wire should be as short as possible. When installed, the equipment grounding wire should be connect to the                      integrated grounding bar. Grounding resistance of requirements bar may be≤ 5Ω, ground connector require preservative treatment. 
        2. Connect the Power
            Connect 220V/50Hz AC power to the equipment power port terminal blocks, power line use 2mm2 cables, length less than 30m.
            For standby power requirement, the power must go through UPS, and then connect the UPS to the repeater power port terminal blocks.
