How to distinguish between good and bad Cell Phone Signal Boosters

Cell Phone Signal Boosters use the backward antenna to receive the mobile station's uplink signal at the same time, and it is processed by the uplink amplification link along the opposite path: that is, through the low noise amplifier, downconverter, filter, intermediate amplifier, upconverter, power amplifier and then transmitted to the base station. Thereby, two-way communication between the base station and the mobile station is achieved.

How to distinguish between good and bad Cell Phone Signal Booster?

1. Look at the workmanship and choose the brand. If you use more, you can disassemble the Cell Phone Signal Booster and compare it.

2. There are many inferior Cell Phone Signal Boosters on the Internet, mainly because some circuits for optimizing the signal, such as automatic gain control, are omitted. Generally, there are less than 80 devices, and a host with complete circuits generally has more than 200 devices.

3. The inferior Cell Phone Signal Booster, after being installed in a large number, will cause serious interference to the base station, making it impossible to make calls if the signal is full. Of course, good quality also has interference, but the same power interference is several times smaller.

What are the installation considerations for Cell Phone Signal Booster?

1. Model selection: Choose different models of Cell Phone Signal Booster according to different areas and building structures.

2. Antenna distribution: The directional Yagi antenna is used outdoors. The direction of the antenna can point to the mobile company's transmitting base station as much as possible to achieve the best receiving effect. The omnidirectional antenna can be used indoors, and the installation height is 2-3 meters (the installation The number and location are related to the indoor area and indoor structure), only one antenna needs to be installed for an indoor unobstructed range of less than 300 square meters, 2 antennas are required for a range of 300-500 square meters, and 3 antennas are required for a range of 500-800 square meters.

3. Cell Phone Signal Booster installation: generally installed at more than 2 meters above the ground. The distance between the installation location of the device and the indoor and outdoor antennas should be routed with the shortest distance (the longer the line, the greater the signal attenuation) to achieve the best effect.

What does Cell Phone Signal Booster do?

Now in some areas, the indoor signal is very weak. After installing the Cell Phone Signal Booster, the signal of the mobile phone can be displayed stronger. However, because the Cell Phone Signal Booster amplifies the wireless signal of a certain frequency, it amplifies the useful signal and also amplifies the interference signal, so the overall SINR value of the mobile phone will not change, and the Internet will not change. almost.
