Working Principle

Mobile Signal Repeater(Technical Terms)
The function of the signal repeater: It first picks up the outdoor cellphone signal by the outdoor antenna and then transmit the signal to the signal repeater through coax cable, which is used to boost the signal, and finally transmit the signal out to the indoor antenna for cellphone signal coverage enhancement. The users in the covering area will have a stable and reliable communication experience.

Technical Terms Introduction

Self-oscillation
Due to the short distance or lack of barrier between the indoor antenna and outdoor antenna, the transmitted signal from the indoor antenna will be received by the outdoor antenna and repeatedly boosted, thus it will generate a lot of useless signals and cause self-oscillation. It is highly recommended the distance between the outdoor antenna and the indoor antenna is more than 8m, preferably blocked by the wall.

Remark:
The cable should be connected to the repeater port tightly, otherwise it will cause self-oscillation.

Signal Busy Area
It often happens in densely populated areas in shopping malls. A single base station serves too many communication terminals. The capacity of the base station cannot meet all the communication needs. As a result, many users in this area cannot communicate normally and transmit data.

Ping-pong Effect
It often occurs on high floors of the building. Because at the high floor window, users can receive signals from multiple nearby base stations at the same time, the mobile phone will switch back and forth between the base stations during the phone call, which results in a good signal displayed by the mobile phone, while the call quality is intermittent.

Directional Antenna
The directional antenna has a clear directivity, which is characterized by strong signal reception, but the receivable direction is relatively small. Therefore, during the installation, you need to carefully adjust the orientation of the antenna to achieve the best reception.

Signal Blind Area

1. It often occurs in mountain areas or remote areas. The signal needs to be transmitted too far with large attenuation, the signal strength is lower than the minimum sensitivity that the phone can receive, causing the phone to fail to receive the communication.
2. There is too much blocking between the mobile phone and the base station, the base station signal is unable to penetrate, and the excessive attenuation of signal strength is lower than the minimum sensitivity that the mobile phone can receive, causing the phone to fail to receive the communication.

The function of the Main Items

(The picture is only an example, the actual product shall prevail)

Coax cable
It is used to transmit the signal from the outdoor antenna to the signal repeater.

Indoor antenna
It is used to transmit the boosted signal out from the repeater

Signal repeater
Process the signal received from the BTS port, and enter the low-noise amplifier by dual filtering through the main board, filter its interference signal and enhance the useful signal, and then transmit out from the MS port.

Outdoor antenna
Pick up the outside signal from the BTS.

LCD Display Introduction

Installation

1. Find a location with a better signal
   First use your mobile phone to check the signal strength, and look for places with higher signal strength around the area where you need to optimize the signal. Test in multiple places to see where the signal strength is better.

   • Places that meet the following criteria are most suitable for installing outdoor antennae.

2. Test outdoor signal step 1
   Connect to the signal repeater, and outdoor antenna by the coax cable, and power on the repeater

   • Do not connect the indoor antenna to prevent self-oscillation

3. Test outdoor signal step 2
   Install the outdoor antenna at the place where the signal is found in “Installation Step 1”, and keep the distance between the signal repeater and outdoor antenna 3-4 meters apart. Adjust the position and orientation of the outdoor antenna, and observe the signal strength on the repeater at the same time, the more of the signal bar, the stronger of the phone signal received by the antenna. After finding the best position of the outdoor antenna, pre-fix the outdoor antenna.

4. Connect to the indoor antenna
   Keep the outdoor antenna position and orientation determined in “Step 3” unchanged, and move the signal repeater to the area where the signal needs to be optimized, and connect to the indoor antenna.

   • Please pay attention to the signal strength on the repeater. If the signal has increased a lot, it may be the distance between the outdoor antenna and indoor antenna is too close, or the lack of barriers, that will cause the self-oscillation.

5. Call quality test
   To allow the mobile phone signal to be quickly switched to the amplified frequency, please make a call first near the indoor antenna, normally within 2meters, and then hang up. Make a call here after 20 seconds, and test the call quality if it is normal. At the same time, check the information displayed on the phone if the signal is improved.

6. Fixed the repeater
   After the performance test is completed and the expected result is achieved, that means the repeater is installed correctly. You can start to fix the outdoor antenna, feeder, and indoor antenna. If the performance test does not reach the expected result, please refer to the following chapter (frequently asked questions)

Frequently Asked Questions

FCCStatement

This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.

1. Usage of unauthorized antennas, cables, and/or coupling devices may result in poor effect and, in severe cases, equipment damage.
2. a complete list of authorized antennas, cables, and/or coupling devices:
3. The default antenna, cable, and/or coupling device that is shipped with the booster Log-periodic Antenna, Panel Antenna, and coaxial cable.
4. The antenna is equipped with a U-shaped mounting bracket. The log-periodic antenna should be installed in a place with good outdoor signal. The panel antenna should be installed indoors and near the main device. If the amplification effect is not good after the installation is completed, the direction of the log-periodic antenna can be gradually adjusted to achieve a better effect.
5. The device has an automatic sleep function, strong anti-interference ability, over-power protection function, good heat dissipation design, and no radiation. The working noise is as low as 6DB.

Warning:
Unauthorized antennas/cables and/or coupling devices are prohibited by FCC rules. Please contact FCC for details: 1-888-CALL-FCC
