HPC-D27 DCS1800mhz Mobile Phone signal booster

How Mobile Signal Booster/Repeater Works?

Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.

Reasons to Purchase Cell Phone Repeater.

1) The Signal Repeater provides the well-organized service that’s why after installation of the system the quality of the connection will be really great.

2) Signal Repeater require no additional wires being attached to your cell phone thus allowing you to use your cell phone without any extra troublesome accessories, in other worlds, no physical connection to your cell phone.

3) They are practical, beautiful and easy to install. You will not need to hire anybody to provide the installation of the equipment. You’ll be able to install it by yourself using only the manual list attached to your repeater.

4) The system can be used by multiple phones. All phones that are under the coverage and are suitable for the frequency of your repeater can use the amplified signals.

5) Signal Repeater is able to cover different coverage: from small to large. In this case you can decide which of our repeater is suitable for your office or supermarket.

6) Repeater works at full duplex. It means that they not only receive the weak signal from the mobile base station and then divert to mobile phone after amplifier. They also receive the signal from your mobile phone and then send it to the mobile base station.

7) Our equipment is completely safe. Mobile repeaters don’t produce any radiation.

The repeater makes the signal stronger in places with poor signal coverage such as:

1) Underground areas: basements, parking lots, tunnels;

2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;

3) Places distant from the BTS like private houses.

HPC-D-27 DCS1800mhz repeater Features:

1.With unique appearance design, have good cooling function

2.With MGC function,(Manual Gain Control), Customer can adjust the Gain as needed ;

3.With DL signal LED display, help to install the outdoor antenna at the best state;

4.With AGC and ALC, make repeater work stable . 

5.PCB with isolation function ,make UL and DL signal not influence each other,

6.Low intermodulation, high Gain ,stable Output power 

HPC-D-27 DCS1800 repeater Inside and Outside Design





HPC-D-27  Dual band repeater is to support any two mobile band existing in the world to help end users to improve mobile signals for much better phone call quality and smoother data transmission. It is designed to support coverage area max can up to 2000 square meters with proper engineering. Below are the main features.

1.The consumer repeater is an ideal solution for providing a cost effective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.

2.Manual gain control (MGC) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.

3.To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

4.Auto shut off function available for both uplink and downlink to avoid deep self-oscilation from jamming the towers, saving your trouble from operators. 

5.Wide band feature enables all devices operating within the wide frequency range of the repeater to see an improvement in performance.

6.Multiple phones and other handheld devices throughout a building can benefit from a wireless repeater.

7.Supports up to (500) users / calls simultaneously.

8.Extended phone battery life. (Your phone does not need to put out as much power due to improved reception.)

The installtion of the Repeater

Outdoor antenna ( for receiving the signal from the BTS ) + Cable ( transfering the received signal) + Repeater ( for amplifying the received signal) + cable( for transfering the amplified signal) + indoor antenna( for shooting the amplified signal), 

(Note : Omni indoor antenna is 3dBi,it can work with about 200m2 . If need repeater coverage larger area , need add more antenna,the HPC-D-27 Max can work with 10pcs indoor antenna.  ( when add antenna ,please remember to take splitters )

Installation steps 

Step 1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.

Step 2 Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later.

Step 3 Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.

Step 4 Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

Step 5 Mount your Indoor (inside) antenna in a productive location. You may need to adjust or move the antenna later. More notes on Indoor antennas and patterns here.

Step 6 Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.

Step 7 Power up the system and check for signal inside the building. If needed, tune system by moving and or pointing the Outdoor and Indoor antennas until they get the most signal possible.

Step 8 Secure all antennas and cables, securely mount the Signal repeater and clean up the installation.

Signal problem & installation technique supporting

1.If still weak signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70DBM. 

2.If still have no signal after installation, please check our device power adapter whether connected perfectly? And connectors connect well.

3.If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line. 

4.Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.
