GeneralThe CSFT922 provides output power levels comparable to Base Sta-

tions in GSM 900 and EDGE networks. The frequency shifting tech-

nology used in the repeater allows a high gain without the stringent

isolation requirements necessary when installing conventional repea-

ters. The CSFT922 consists of 2 units, a Donor Unit at the BTS site

red to handle up to 2 GSM/EDGE carriers.

Features� Output power comparable to a base station - up to 20 watts.

� Minimal antenna isolation requirements.

� Convection cooling.

• Can be mounted almost anywhere.

• Comprehensive remote control and supervision possibilities.
