Long Distance 37dBm GSM 900MHz Ics Wireless 2g 3G 4G Cell Phone Signal Booster
China Long Distance 37dBm GSM 900MHz Ics Wireless 2g 3G 4G Cell Phone Signal Booster, Find details about China GSM Repeater, Ics Repeater from Long Distance 37dBm GSM 900MHz Ics Wireless 2g 3G 4G Cell Phone Signal Booster
Features:
· Aluminum-alloy casing has a high resistance to dust, water, and corroding;
· No stringent isolation requirement for antenna installation;
· Adopting WDM (Wavelength Division Multiplexing) module to realize long-distance transmission;
· USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise the repeater's working status and download operational parameters to the repeater.
And both types of FSR can be sorted into 2 sub-categories as per the availability of link frequency:
* In-Band FSR: The link frequency is within the working band of BTS;
* Out-of-Band FSR: The link frequency is out of the working band of BTS.
The FSR is mainly applicable to such case:
The area to be covered is far away from the BTS and has no fiber optic connection;
The distance between the BTS and the area to be covered is 20 km around.
In comparison with RFR (RF repeater) and FOR (fiber optic repeater), the FSR has the following benefits and disadvantages:
Pro:
· No more self-oscillation and easy to choose installation location;
· For Cable-Access type, pure BTS signal picked up by the Donor Unit will greatly reduce the signal noise;
· The Remote Unit can be installed out of the BTS coverage;
· A full 360-degree coverage can be realized;
Con:
· The total cost of equipment is higher;
· A certain frequency resource is required to be occupied as the Link Frequency;
A line of sight shall be viewable between the Link Antennas.
