1 SR-1910 REPEATER INTRODUCTION

The SR-1910 GSM1900 Band Adjustable Repeater is used where small-scale signal coverage for city
structures is desired (e.g., hotels, department stores and shopping malls, underground parking lots and
tunnels, convention centers, arenas, airports, etc.)
The SR-1910 is designed for indoor operation in the GSM1900 band. The band-specific linear amplifier
amplifies the desired BTS band and IF filtering effectively provides superior out-of-band rejection.
Local and remote configuration and surveillance is possible through laptop by using Comba's OMT/OMC
softwares. Internal Li-ion backup battery ensures alarm signals can be sent out in the event of power
failure.
The SR-1910 comes in a completely sealed, well-ventilated cast aluminum enclosure and is suitable for
indoor and sheltered outdoor environment.
