Dual Band DCS/WCDMA1800/2100MHz Mobile Signal Repeater With Antennas

 

What Is A Cell Phone Signal Booster?

Cell Phone boosters or cell phone repeaters are devices that have been developed to solve the problem of weak cell phone reception. They have been designed specifically to amplify a weak signal available outside a house, building or a vehicle, and to broadcast a much stronger signal inside, where it is needed the most.

We shall discuss in detail how these devices work, but let us first answer the question, are cell phone signal boosters legit? Yes, they most certainly are and have been approved by the FCC in United States and Industry Canada (IC) in Canada.

The FCC has no issue with using cell phone repeaters to extend the range of a cell network in areas that historically receive poor cellular service, including homes and offices, commercial structures and more as long as they are registered with respective service provider before use.

 

Description:
Indoor Dual Band Signal Repeater (Signal Booster) series is an ideal solution for two wireless system in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.
The signal booster improves mobile signals with no negative impact on human health.


 

Features:

1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption, easy installation, great cover.
3. Expansion and extending of the signal of base station.
4. Optimization of the quality of the signal and source
5. Cover about 1000~5000m² without block or obstruct.

How A Cell Phone Signal Booster Works.

A cell phone booster pulls in a weak signal from the outside, boosts it and then rebroadcasts it within the house, building or vehicle. A typical signal booster is based on a three-part system.

It consists of an outside antenna that captures the weak cell signal, an amplifier that boosts the signal thus received, and an inside antenna that rebroadcasts the much enhanced signal within the room, house, building or vehicle.

An outside antenna is mounted in a location outside the house or building which currently gets a signal, usually on the roof. This signal is then passed from outside antenna to a signal amplifier within the building. An amplifier enhances the signal by up to 32X times and then sends it to the inside antenna. An inside antenna rebroadcasts the signal to the area where it is needed the most.

That is how you get a much improved signal from the cellular tower. The same process works in the reverse. The signal from your phone is picked up by inside antenna, enhanced by amplifier and sent out to the outside antenna, which rebroadcasts it so that a much stronger signal is received by the cellular tower. This establishes a strong two-way communication between your phone and the cellular tower.

 

Amplifier.

An amplifier or a cellular repeater receives the signal from the outside antenna and boosts it by 32X times. Amplifiers are measured in terms of dB (decibel) output. Amplifiers used in home-based systems offer anything from 500 to 20,000 sq. ft. of coverage.

Most exterior cell phone signal strength ranges from -50 dB to -120 dB. In terms of bars, -50 dB means full bars and -120 dB means zero bars or a dead zone. Amplifiers boost the cell phone signal so as to get the reading closer to -50 dB.

You should get a +60 dB gain at least with an amplifier. The best and most powerful amplifiers give you a +70 dB gain. Amplifiers that have been specifically designed for vehicles should give a +25 dB gain at least, with a maximum of +50 dB gain.

If you are able to get a consistent -94dB or better signal outside, then signal amplifier will be able to multiply signal to boost reception indoors substantially. However, the typical cut off point for signal boosters to be able to amplify is -105dB outside signal. If exterior signal is less than that amount, say for example, -115dB, then signal amplifier will not be able to help in such a situation.
