1 Description

Repeater is a device that receives, amplifies and transmits the radiated or

conducted RF carrier both in the down-link direction (DL, from the base station

to the mobile area) and in the up-link direction (UL, from the mobile to the base

station).

The wide band repeater (PORP23) is a bi-directional amplifier used to

enhance signals between a mobile and a base station. This repeater type is

used for 3G system:

1) -It picks up the strongest signal from BTS via the Donor Antenna,

2) -Linearly amplifies the signal and then retransmits it via the Indoor

Signal Distribution System to the weak/blind coverage area.

3) -And the mobile signal is also amplified and retransmitted to the BTS

via the opposite direction.

It is applied to small, medium-size areas such as home, offices, shops, and

basements, remote countryside , and mining well etc.

This model booster is commonly used in situations where large numbers of

4 System Diagram

The RF link (donor) towards the base station is typically fed from an

outdoor antenna while the coverage area is fed by an indoor antenna

The RF link (donor) towards the base station is typically fed from an

outdoor antenna while the coverage area is fed by an indoor antenna or

connected to mobile antenna directly.

The signal from the base station is received via directly antenna, then

forwarded through a duplex filter, is amplified in a low noise amplifier (LNA),

enters the RF filter for wideband selective, and then amplified in the power

amplifier.

The output signal passes a duplex filter, before it is fed to mobile or indoor

antenna which retransmits the signal to the aim areas.

User Manual

5.1 Minimum Signal Levels

It requires a minimum signal level in the place where install the donor antenna.

Failure to provide sufficient input signal will only result in a poor coverage

inside the building for this repeater system.

To check signal levels, use the phones in the place where antenna be install

(on the roof) and observe the signal bars on the phone. The Donor (outside)

antenna should be placed in the location where you get the most signal.

Notices:

1) The donor antenna should have line of sight (LOS) with the BTS antenna.

If the signal strength is adequate, LOS may in some cases not be

necessary.

2) Donor antenna gains are typically 9 to 14 dB, and have a horizontal and

vertical beam width of less than 30° to correctly select the donor BTS.

5.2 Custom Applications

If building is made of concrete, steel, steel roof, copper roof, brick, aluminum

siding, concrete roofing tiles, metal roofing tiles or any other signal stopping

material, a repeater is usually the ideal solution for your situation.

-- 3G Wide Band Repeater (Model: PORP23W)

User Manual

Most homes or buildings are easily covered by one repeater systems. Some

buildings are larger or have multiple areas inside that need coverage.

It may need longer cables, more than 2 coverage antennas or other items in

order to fully cover your building. We can make (almost) any cable length and

can help design a system that fits your application.

5.3 Isolation and Separation

Isolation refers to the proper distance or separation needed to keep the Donor

antenna signal pattern and the Coverage antenna signal pattern away from

each other.

Isolation becomes particularly problematic when Omni-directional antennas

are used for both the Donor and the Coverage antennas. Since these

antennas transmit in a circle (or more accurately a sphere) it is very easy for

these spheres to overlap and thus negate the repeater system.

6 Production Operation

6.1 Notices

Follow below safety items carefully before installation, implementation,

maintenance and operation for this product

 BS and MS port must be connected to donor antenna and service antenna

when powers supply on; otherwise the equipment will be damage for long

term use.

 When use repeater for outdoor, the distance between donor antenna and

service antenna must be >20metes, otherwise the repeater will be damage

because isolation problem for long term use.

 Donor antenna need to be lighting proof and lighting rod need to be install

for donor antenna installation pole outside

 Check input power, require input power less than maximum input power of

repeater, otherwise the repeater cannot work well.

 Keep clear for label and indicator on surface of repeater to be identified.

6.2 Installation

Step 1: Start by taking phone up to the roof or other location outside to find

where the signal is strongest.

Step 2: Temporarily mount the Donor (outside) antenna in that location. It

may need to adjust and move the antenna later.

Step 3: Run coaxial cable into the building to a convenient location where

you can also get standard 220VAC power for the repeater.

Step 4: Place the repeater in that location and connect the coaxial cable to

the Donor Side of the repeater and the donor antenna.

Step 5: Mount coverage (inside) antenna in a productive location. It may

need to adjust or move the antenna later.

Step 6: Connect coaxial cable between the coverage antenna and the

repeater output port.

User Manual

Step 7: Power up the system and check for signal inside the building. If

needed, tune system by moving and or pointing the Donor and Coverage

antennas until get the most signal possible.

Step 8: Secure all antennas and cables, securely mount the repeater and

clean up the installation.

DIP SWITCHES

There are downlink (BTS site to )DIP Switches (Hi ATT) and uplink DIP

Switches (Lo ATT) for single band.

 ON- means Attenuation

 OFF- means no attenuation.

-- 3G Wide Band Repeater (Model: PORP23W)

User Manual

 Hi ATT are used when BTS signal is acquired is too strong via donor

antenna (external antenna), which usual are set to lower gain (higher

attenuation), and protect repeater to work at good signal situation (NOT

Over-power state).This simply setting way is:

 Set ALL DIP switch off.

 Check signal bar of mobile phone in edge of coverage area.

 Set Attenuation as following table until cell phone make calling is well.

 You can change donor antenna direction or installation position to get

bigger signal;

 You can set attenuation to add or reduce repeater gain; or you can check

cable and connector link status to reduce cable loss and insert loss

between repeater and antenna.
