20W GSM900MHz Air Coupling Frequency Shifting Repeater is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS).

As per the method of receiving BTS signal by the Donor Unit, two types of FSR are available:
1. Cable-Access FSR: To receive BTS signal via a direct coupler closed to the BTS (Recommended);
2. Wireless-Access FSR: The receive BTS signal via a Donor Antenna (applicable when no line of sight can be viewed between the Donor Unit and Remote Unit as the Donor Unit is installed on the BTS tower).

And both types of FSR can be sorted into 2 sub-categories as per the availability of link frequency:
1. In-band FSR: The link frequency is within the working band of BTS;
2. Out-of-Band FSR: The link frequency is out of the working band of BTS.

Mainfeature: Main Features
1. High isolation full duplex design, easy to install.
2. Low noise figure, high receive sensitivity.
3. With ALC and MLC function to ensure stable output power.
4. Low power consumption, environmental protection and energy saving.
5. Modular structure design, easily to upgrade the system.
6. High Q cavity filter and SAW surface acoustic wave filter, high out of band rejection.
7. Adopt the world’s most advanced high linearity, low intermodulation LDMOS power amplifier.
8. Adopt the advanced digital PLL, TCXO, OCXO technology, frequency stability and high accuracy.
9. Perfect remote and local network monitoring function.
10. Waterproof design work for all weather indoor and outdoor.

Application&scenarios

Frequency shifting repeater Applications
    To expand signal coverage of fill signal blind area where signal is weak
or unavailable.
   Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
   Indoor: Hotels, Exhibition Centers, Basements, Shopping
Malls, Offices, Packing Lots etc.
It is mainly applicable to such case:
    The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than ‐70dBm;
    And can meet the requirement of antenna isolation to avoid self‐oscillation.
