Introduction
The R25FB0-GSM-DB is a high power 2 subband selective repeater for GSM applications and can be applied as an indoor or outdoor solution. The R25FB0-GSM-DB allows operators the option of having two sub-bands which are dis-continuous, without the frustration of improving a competitor's coverage which lay in between the sub-bands.
The R25FB0-GSM-DB is equipped with a remote OMT/ OMC function, allowing for easy remote access for monitoring and configuration purposes from the control centre. Its enclosure is designed to handle the harshest environments.
The R25FB0-GSM-DB is a cost-effective 2 subband selective repeater that will reduce the overall cost of signal coverage extension without the added need of implementing more BTS sites. The R25FB0-GSM-DB can be applied to much large areas including shopping malls, exhibition halls, parking lots, and restaurants.
