Mobile phone signal jammers are not only beautiful in appearance, but also easy to operate.
The advantages of mobile phone signal jammer manufacturers are that they use high-dispersion aluminum alloy shells, low operating temperature, and more stable shielding effects. Built-in silent turbine fan, low operating noise. Independent power adapter. 12V/24V DC power supply operation, convenient for vehicle-mounted mobile operation. The antenna is designed externally, and the interface at one end makes the appearance more beautiful and decent. And it has an anti-loosening design, and the antenna and the host have marked operating frequency bands for easy one-to-one correspondence. Through use, we can find that mobile phone signal jammers have many advantages. Not only are they beautiful in appearance, but they are also easy to operate. It can be said that as a more useful instrument, it can shield signals of different frequencies.
During the operation, scan the low-end frequency of the channel to the high-end at a certain speed. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of shielding the mobile phone signal.
The mobile phone receives the frequency sent by the base station and the wireless router through its own frequency, thereby shielding them. Within a certain frequency range, mobile phones and base stations are connected through radio waves, and data and sound transmission is completed at a certain baud rate and modulation method. During operation, the low-end frequency of the channel is scanned to the high end at a certain speed. The functional characteristics of electromagnetic waves are determined by their frequency. Mobile phones need to emit electromagnetic waves that meet the requirements before they can connect to the base station of the communication operator. The jammer emits the same radio frequency as the mobile phone. Because the frequency is the same, the mobile phone cannot distinguish which signal is the regular base station signal, completing "interference". In a cyclical manner, the interference bands corresponding to the three signals are repeatedly broadcast, covering the three bands at one time, and the distance of this cycle is small, resulting in the mobile phone having basically no chance to speak.
Is electromagnetic waves harmful to the human body and how bad are they? These issues should be viewed from a scientific perspective. We know that the spectrum of electromagnetic waves is very wide, and light waves are electromagnetic waves. Some electromagnetic waves are harmful, while some are harmless. There are many kinds of rays and electromagnetic waves in the universe. Humans have lived on the earth for tens of thousands of years and have adapted to this environment and continue to reproduce and thrive, which poses no threat to humans. However, humans must protect themselves when entering space. It can be seen that electromagnetic waves that reach a certain intensity will have an impact on the human body. For example, light waves in electromagnetic waves, humans cannot live without sunlight, but excessive sunlight can also cause damage to the human body. There are two ways to explain the impact of electromagnetic waves on the human body: one is thermal effect; the other is biological effect.
