UMTS 3G 2100MHz WCDMA Line GSM Signal Amplifier for Extend Signal Coverage
Line Amplifier Description:
Line amplifiers are actually applied as linear amplifier, it is used as the indoor coverage solution and must worked with mobile signal repeater. It amplifies transmitting RF signal in order to compensate signal loss by excessive cable or components.
It is composed by two independent links: Uplink (or Forward Link) and Down Link (or Reverse Link). Downlink receives donor signals from BTS or Repeaters and amplify the donor signals; Uplink receives and amplifies signals from MS, in order to improve indoor coverage extension
Amplifier enhances consumer satisfaction greatly with its integrated design, compact size, easy engineering and rapid installation and debugging.
Line Amplifiers are specially designed to assist the Base Station (BTS) or Repeaters to compensate the system loss from in-building distributing cable, power splitter and directional coupler and extend in-building signal coverage, and improve flexible of in-building signal coverage system design
To meet the field strength requirements of in-building signal coverage system.
Please keep away from heating-equipment, because the booster will dissipate heat when working. And do not cover booster with anything that influences heat-dissipation.
Eliminate dropped calls and increase data speeds with a signal booster.
Line Amplifier Features:
1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption,
3. easy installation, great cover.
4. Expansion and extending of the signal of base station.
5. Optimization of the quality of the signal and source
6. Wide band signal booster, or customize selective band booster.
7. High linear design, ALC function design, low interference to BTS.
8. Support any cellular devices (voice & data & video)
Line Amplifier Advantages:
Digital Display Panel, Intelligent mode setting
Smart function called which can be activated via the digital display panel.
Users can choose gain and working system by LED Digital Panel.
Set the technical parameters simple and efficient, this is easier than DIP Switch.
Line Amplifier Application:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
Indoor: Hotels, Home, Basements, Shopping Malls, Offices, Parking Lots, Shop.etc.
