Introduction
The R23DB0-GSM-DB is a high power double band selective repeater for GSM applications and can be applied as an indoor or outdoor solution. The R23DB0-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 R23DB0-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 R23DB0-GSM-DB introduces a smart button function which allows the repeater to automatically adjust repeater parameters to optimum performance. Consisting of an intelligent circuit, it allows the repeater to periodically analysis the surrounding environment and adjust repeater parameters to minimise noise interference to the BTS.
The R23DB0-GSM-DB is a cost-effective double band selective repeater that will reduce the overall cost of signal coverage extension without the added need of implementing more BTS sites. The R23DB0-GSM-DB can be applied to much large areas including shopping malls, exhibition halls, parking lots, and restaurants.
