10W 2100MHz Cell Phone Signal Boosters , 3G WCDMA UMTS Repeater for Big Building
Description:
Mobile network carriers use various frequencies for transmitting data to our cell phones.
Greetwin has developed an exhaustive range of highly performant 3G 2100 Wide Band Repeaters that would accommodate your requirements towards the device in terms of operating frequencies for calls and Mobile Data as well as coverage.
3G 2100MHz Wide Band Repeaters are cost effective and reliable solutions designed to extend and improve the coverage area of 3G communication systems. GW-40W RF Repeater is designed to solve problems of 3G mobile signal, which is much cheaper than adding a new base station (BTS). Main operation of the repeaters are to receive lower-power signal from BTS via RF transmission and then transmit the amplified signal to the areas where network coverage is inadequate.And the mobile signal is also amplified and transmitted to the BTS via the opposite directon.
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.
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;
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:
|
Pro |
Con |
|
· Easy to build the installation site; · Lower cost of equipment and site-building. |
· Inappropriate installation may cause self-oscillation; · The Coverage Antenna shall face against the Donor Antenna, which limits the coverage angle; · · High signal noise may be introduced since the Donor Antenna picks up signal from the air; · The repeater shall be installed within the coverage of BTS. |
