Product Introduction
Triple Band Wireless Repeater 33dBm 2W
Model No.: CRF-GDW-S33TR
Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). The main operation of the RF Repeaters system is to receive low-power signals from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
Main Features
Ideal for sophisticated urban and rural RF environments, Band Selective Repeater takes selected BTS channel as donor signal source.
ALC (Auto Level Control) with wide range of input level: -20dBm~-110dBm..
Output power detection and self-oscillation protection.
SAW filter with superior out of band rejection, custom frequency band.
Integrated GSM modem with OMT software. Support optional OMC/NMS.
IP65 case designed for all kinds of tough outdoor and indoor environments.
Highest standard industrial standards applied, with MTBF over 60,000hrs.
Applications
Expand signal coverage of fill signal blind area where the signal is weak or unavailable.
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages, etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Parking Lots, etc.
It is mainly applicable to such cases:
The repeater can find an installation place that can receive pure BTS signal at a strong enough level as the Rx Level in the repeater site should be more than -70dBm;
And can meet the requirement of antenna isolation to avoid self‐oscillation.
