Description

75dB 23dBm 2100MHz 4 Sub-bands Cell Phone Signal Boosters with SMS Control

Model. GW-23DR-W

Signal Booster Description:

Greetwin GW-23DR-W Model can amplify radio coverage for up to five independent frequency bands for different mobile radio providers. The device provides the most cost-effective solutions to improve user experience of high quality mobile services in small to medium sized indoor areas such as houses, hotels, hot spots, shops, offices, meeting rooms, apartments, and so on.

The machine is a kind of digital repeater which is single band of WCDMA 2100 with 4 sub-bands. The 4 sub-bands can work independently without any influence with each other. It’s designed to support one mobile system and help mobile operators to amplify their own mobile signals. It supports to adjust the sub-band and the channels by software to adapt to the operators’ requirement s without any change on the hardware. The repeater is also equipped with OMT / OMC remote control and monitoring system allowing to configure and control the device operation remotely via PC or wireless modem (optional function). The built-in backup battery will ensure the operation of the device even with a sudden power failure (optional function).

Signal Booster Equipment Compoments:

Digital repeaters main compoments as follows:

Copoments Specifications Quantity Unit Remarks
Main Master NXWXSB201821230111 1 Piece
Network Line 1M*R45 1 Piece
Ground Wire 1.5mm² 1.5 Meter Ended with metal sheet
Expansion screw M4*100mm 4 Piece
Mounting bracket / 2 Piece
Mounting bracket screw M6*14mm 4 Piece
Whip Antenna 800~2700MHz 1 Piece Used for Modem

Signal Booster Working Principle:

The principle of Digital Band Selective Repeater is the downlink signal received by the Donor Antenna of the base station shall be sent to a band selective filter via duplexer to be filtered and to be amplified by the downlink band selective amplifier to a proper level. The Coverage Antenna via a duplexer shall emit the downlink signal. Similarly, the signal received by the Re-transmission Antenna shall have its level adjusted to a regulated level by a uplink band selective amplifier after it is filtered. The Donor Antenna will emit it after it is filtered and sent to the duplexer.

FAQ:
1. After installing booster signal not be very good, indoor signal coverage very small ?
> Adjust outdoor antenna's location and direction
> Change another high gain outdoor antenna
> Check whether cables are connected well
> Change more powerful repeater

2. Cell phone signal full bar, but communication quality bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.

3. After installing booster not only signal be good, but also more bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.

4. Working good for long time, suddenly signal bad ?
> Check whether outdoor cable connectors are flooded
> Check whether power light is working normally
> If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
