10 Watt GSM 850Mhz Mobile Signal Repeater using for Airport, Tunnel ,Village
The 10W Mobile Signal Repeater is the kind of repeater used
most frequently. It has a simple structure to transparently convey
and amplify the wireless signal (at the same frequency) between the
BTS (Base Transceiver Station) and mobiles in Dual wireless
network.
The 40dBm Mobile Signal Repeater is working as a relay between the
BTS and mobiles. It picks up the signal from the BTS via the Donor
Antenna, linearly amplifies the signal and then retransmits it via
the Coverage Antenna (or the Indoor Signal Distribution System) to
the weak/blind coverage area. And the mobile signal is also
amplified and retransmitted to the BTS via the opposite direction.
Features:
* Aluminum-alloy casing with IP65 protection has high resistance to
dust, water and corroding;
* Highly selective channel selector can process multiple channels
simultaneously;
* No interference to BTS by adopting linear amplifier with high
gain and low noise;
* Adopting filter with highly selectivity and low insertion loss
eliminates interference between uplink and downlink;
* (Optional)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
repeater's working status and download operational parameters to
the repeater.
The RF Repeater is mainly applicable to such case:
*The repeater can find an installation place which can receive pure
BTS signal at strong enough level and can meet the requirement of
isolation to avoid self-oscillation;
*And the distance between the BTS and the area to be covered is 2km
around.
In comparison with FSR (frequency shift repeater) and FOR (fiber
optic repeater), the RF Repeater has the following benefits and
disadvantages:
Pro:
Easy to build the installation site;
Lower cost of equipment and site-building.
Con:
*Inappropriate installation may cause self-oscillation;
*The Coverage Antenna shall face against the Donor Antenna, which
limits the coverage angle;
* High signal noise may be introduced since the Donor Antenna picks
up signal from the air;
*The repeater shall be installed within the coverage of BTS.
Application:
To expand signal coverage of fill signal blind area where signal is
weak or unavailable.
Indoor: Hotels, Home, Basements, Shopping Malls, Offices, Parking
Lots, etc
Outdoor: Airports, tourism regions, golf courses, tunnels,
factories, mining districts, villages, highways
