Mobile phones are an important communication tool in today's society. With the development of mobile phones, mobile phones are not only a communication tool, but also an essential device in our lives and work. It enriches our entertainment life so that we can learn more about the outside world and keep up with the times. A mobile phone is a device that needs a signal to work, and a mobile phone without a signal is like a brain without a brain. With the development of science and technology, mobile phone signals are gradually upgrading. From the initial 2g and 3g to the current 4g, the speed has been greatly improved, which can meet people's demand for the Internet.

The mobile phone interference signal is the signal of the mobile phone, you need to prohibit the use of the mobile phone here. For example, in a large conference room, mobile portable jammer will need to be used to ensure the quietness of the venue. For example, in schools, in order to make students study hard, they cannot cheat on their mobile phones in exams and install mobile jammers. Obstruct driving. The driver has only one hand, which is a big obstacle to the vehicle. It will affect the speed control, the distance between the car and the driver’s line of sight, which can easily lead to traffic accidents.

When chatting on a mobile phone, the pilot will be distracted and interfere with the observation of the road and the surrounding environment. Once an emergency or emergency occurs, it will greatly weaken the driver's resilience and reaction time, and easily cause a traffic accident. The test results recently released by the British Transport Association show that when using a mobile phone while driving, the brain’s reaction speed is 30% slower than when drunk. Young people answering the phone are equivalent to a 70-year-old man driving in a car accident. Normal driving is more than four times higher, and 70% of fatal accidents are caused by driver negligence. Studies have shown that driving a mobile phone can cause the driver to lose 20% of his attention, and even 37% if the call is important. At the same time, drivers who make calls are 9% slower than normal people, and brakes are 19% slower. Narrow field of vision The driver’s line of sight becomes narrower and the surrounding vision is reduced. In related tests, drivers who focused on driving had more information than drivers who were distracted, resulting in "blindness." Drivers using mobile phones are more likely to miss traffic lights and often fail to see bulletin boards and other signs.
