The shadow behind the splendor of every big city is the village in the city. For example, there are many large and small urban villages in Guangzhou. Shipai Village is the largest and oldest among them. People’s first impression of urban villages is crowded, noisy, and a lot of garbage. The alleys are densely packed, with wires and spider webs crisscrossing overhead.
Because the village is too dense and surrounded by high-rise buildings, the village in the city has a weak signal or even no signal at all in addition to being dark and humid. However, most of the people living in urban villages are fresh graduates or young people who have come to the city to struggle. The lack of mobile phone signal is very difficult for young people to accept. The lack of mobile phone signal not only affects their social activities, but also affects their job prospects. Therefore, many renters hold a mobile phone when they look at the house, and when they come in, if there is no signal in the house, they immediately shook their heads and left.
So, how to solve the problem of bad mobile phone signal? The cell phone jammer is a wireless communication device, which is different from general electrical installations. It may seem simple to install such wireless communication devices, but there are many knowledges in it:
1. First of all, before installing the equipment, fully test the signal and electromagnetic environment to determine the type of equipment, wire and antenna to be selected. To complete this work, it is difficult to do without relevant instruments and professional knowledge. Many people did not understand the reason and bought the equipment and materials at will, but the results were ineffective, and money was wasted.
2. Secondly, during the installation process, there are certain tricks in the design, layout and connection of the circuit. The same equipment and materials, let professional and technical personnel and ordinary electricians to install, the effect will be different, let alone ordinary people.
3. Once the equipment is installed, it needs to be debugged carefully. Equipment debugging is a complex and professional work, which is often far from perfect, and it is difficult for it to be a professional.
4. Finally, the current mobile phone signal amplifiers on the market are mixed, and most of the products are not guaranteed in quality. Many machines only have amplifier circuits, but there are no quality control and anti-interference control circuits. It felt good at first, but it didn’t take long to get worse. Such an amplifier is not only easily affected by environmental changes, but also has a great impact on the surrounding electromagnetic environment, and even interferes with the normal operation of the base station.
At present, many rental houses in urban villages have installed cell phone signal amplifiers, but most of the owners buy them and install them by themselves. In addition, because of the desire to be cheap, the quality of the equipment purchased is very poor, so the signal effect is not good. How many companies have made the outdoor signal environment more and more complicated.
