1900MHz PCS Cell Phone Signal Repeater 10W Frequency Wireless Access
10W Signal Repeater Description:
The BTS in the suburbs and countrysides are mainly built in the
township where the government is located and the population is
relatively concentrated. Many villages can not receive mobile
signals due to the far distance from the BTS.
In the suburbs and countrysides, the signal coverage is mainly to
solve signal blind spots and signal weak zones problem, and the
teletraffic is not the main contradiction. At present, the basis of
the circuit of the wired network is poor in villages, so it is
difficult and costly for the layout and the construction of the
cable. Using the wireless network bridging, increasing and
extending the coverage range of the base stations has become the
ideal rural network access.
The Frequency Shift Repeater (FSR) is designed to solve problems of weak mobile signal, which can
expand more coverage than RF repeater and reduce investment for the
areas where fiber optic cable is not available.
The whole FSR system consists of two parts: Donor Unit and Remote
Unit. They transparently convey and amplify the wireless signal
between the BTS (Base Transceiver Station) and mobiles via RF wave
at different frequency from the BTS.
The Donor unit receives the BTS signal via a direct coupler closed
to the BTS (or via open air RF transmission through the Donor
Antenna), then converts it from the working frequency to the link
frequency, and transmits the amplified signal to the Remote Unit
via the Link Antennas. The Remote Unit will reconvert the signal to
the working frequency and provide the signal to the areas where
network coverage is inadequate. And the mobile signal is also
amplified and retransmitted to the BTS via the opposite direction.
As per the method of receiving BTS signal by the Donor Unit, two
types of FSR are available:
1. Cable-Access FSR: To receive BTS signal via a direct coupler
closed to the BTS (recommended);
2. Wireless-Access FSR: To receive BTS signal via a Donor Antenna
(applicable when no line of sight can be viewed between the Donor
Unit and the Remote Unit as the Donor Unit is installed on the BTS
tower).
And both types of FSR can be sorted into 2 sub-categories as per
the availability of link frequency:
1. In-Band FSR: The link frequency is within the working band of
BTS;
2. 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:
In comparison with RFR (RF repeater) and FSR (frequency shift
repeater), the FOR 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.
10W Signal Repeater Application:
To expand signal coverage or fill signal blind area where signal is
weak or unavailable.
· Outdoor: Airports, tourism regions, golf courses, tunnels,
factories, mining districts, villages, highways
· Indoor: Hotels, exhibition centers, basements, shopping malls,
offices, parking lots.
