40dBm 1800MHz Cell Phone Signal Boosters , DCS Signal Amplifier with AGC Function

Cell Phone Signal Booster Description:

A mobile phone signal repeater provides the ultimate solution in any area where
Cellular communications can not work well due to leak of signals,the repeater
Device features easy installation & operation ,build-in indoor antenna and no
Interferece,it could also improve indoor electromagnetism environments.

Protract cellular battery life and reduce radiation of cellphones.
A mobile phone repeater is ideal for house ,home,office use.

The Single-Band RF Repeater is the kind of repeater used most frequently. 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 single wireless network.

The Single-Band RF Repeater is working as a relay between the BTS and mobiles.

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.

As per operator’s requirement for working frequency, two types of Single-Band RFR are available:

1. Band-Selective Single-Band RF Repeater: to amplify all signals in the whole band (bandwidth is customized);

2. Channel-Selective Single-Band RF Repeater: to amplify only the signals transmitted in the customized 1/2/4/8/16 channels.

Cell Phone Signal Booster Features:

· Aluminum-alloy casing has high resistance to dust, water and corroding;

· AGC (automatic gain control) function to prevent self-oscillation;

· Highly selective channel selector can process multiple channels simultaneously;

· No interference to BTS by adopting linear amplifier with high gain and low noise;

· Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;

Cell Phone Signal Booster Application:

To expand signal coverage or fill signal blind area where signal is weak or unavailable.

· Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, highways…

· Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots.

The Repeater is mainly applicable to such case:

· The repeater can find an installation place which can receive pure BTS signal at strong enough level and can meet the requirement of isolation to avoid self-oscillation;

In comparison with FSR (frequency shift repeater) and FOR (fiber optic repeater), the RFR has the following benefits and disadvantages:
