Product Details

2W EGSM 900MHz Digital Cell Phone Signal Boosters with Mobile Bandwidth

 

Model. GW-33DR-E

 

Cell Phone Booster Description:

 

Greetwin GW-33DR-E model is to provide multiple re-configurable digital filters in a repeater so that users can set any preferred frequency segments within the operating band for repeating. Accompanying with independent gain and output power control among different sub-bands, is the most cost-effective solution for the different operators.

 

The machine is a kind of digital repeater which is single band of EGSM 900 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).

 

 

Cell Phone Booster Features:

    1. Stably working,low power consumption,fit in with industry standard

    2. Digital technology, many SAW filters ensures enough output level and out-band suppression.

    3. High isolation,strong compatibility,convection cooling,light weight, convenient installation.

    4. Local RJ45 monitoring and remote monitoring conform to communication monitoring protocol        standard, which is convenient for engineering commissioning and maintenance.

Cell Phone 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.
