GSM900 DCS1800 Dual band signal booster Coverage 2500m2

GSM900 DCS1800 Dual band signal booster Coverage 2500m2

Description 

There are millions of very small areas (10~2500 square meters) where people work or live in and suffer from very poor or no mobile signals. People are seeking a cheap and immediate solution that would allow them have clear phone calls or higher speed broad band. However most of the current repeater solutions usually have larger coverage size, which is cost effective. ST-GD-27A is specifically designed as a "CHEAP" solution to meet this request.

1. The consumer repeater is an ideal solution for providing a costeffective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.

2. Manual gain control (MGC total 31dB range with all DIP switches for each link) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.

3. To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

4. Auto shut off function available for both uplink and downlink to avoid deep self-oscilation from jamming the towers, saving your trouble from operators.

 

5. It supports two systems of GSM900 and DCS1800mhz.

HPC LCD Dual band repeater Features:

 

     1. With unique appearance design, have good cooling function
