Since the mobile phone can automatically increase the power when it encounters slight interference, the jammer must be able to recognize the power increase of the mobile phone and increase its power accordingly.The mobile phone is a full-duplex device, which means that it uses two separate frequencies for speech and listening. Some jammers only block one frequency, but they also have the effect of blocking two frequencies at the same time. Since the mobile phone can only receive one frequency at this time, it will mistakenly believe that the mobile phone has no service. Every year during the college entrance examination, the school will have network problems such as mobile phone disconnection and slow Internet speed. That is because the school has opened a cell phone jammer .If we think of a mobile phone as a handheld two-way radio, the radio can be interfered, and the mobile phone is no exception. Like any radio, the signal of a mobile phone will be interfered.Interfering with mobile phones is like interfering with any other type of radio communication. The mobile phone communicates with its service network through the base station. When mobile phone users drive down the street, the signal is switched from one base station to another.We know that wireless communication uses electromagnetic waves for communication. The functional characteristics of electromagnetic waves are determined by their frequency.At present, the main principle of signal shielding and signal jamming is to emit huge noise in the frequency band used by mobile phones, which interferes with the reception and transmission of normal signals of mobile phones. This small object is not only often used to prevent cheating in exams, but also politically and militaryly to prevent terrorist attacks. However, signal jammers are not like shopping for food, they are not bought and used casually, otherwise they may be illegal.

It’s great to be able to call people at any time.Everyone next to them has to share such private conversations. Who hasn’t experienced it before? Although most people can only grumble and give up, some people go to extremes and retaliate.A mobile phone is essentially a handheld two-way radio communication device. Unfortunately, restaurants, cinemas, concert halls, shopping centers, and churches are all suffering from mobile phones, because not all mobile phone users know when to keep quiet. The speaker and his friends chat about some private topics on their mobile phones. Like all radio devices, the signal can be blocked or interfered. Interfering with mobile phones is the same as interfering with other types of wireless communications. The mobile phone communicates with its service network through the base station. The base station divides the city into many small areas, called cells. This article will introduce the working principle of cell phone jammer and the legality of their use.When a mobile phone user is driving on the street, the signal is between different base stations transfer.The interfering device emits the same radio frequency as the mobile phone, thereby interfering with the communication between the mobile phone and the base station. Signal jammer is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of mobile phones is prohibited. To interfere with cell phone signals, all you need is a device that can broadcast on the correct frequency. Although different cellular systems process signals in different ways, the radio signals used by mobile phone networks can be blocked. The GSM network used in digital cellular and PCS systems operates in 900MHz and 1800MHz in Europe and Asia, and 1900MHz (sometimes 1.9GHz) in the United States.

This product can eliminate the false alarms of daily metal life items carried by the tested person’s body, and adopts passive passive induction detection method throughout the whole process, and does not cause radiation damage to the tested person and objects. With high sensitivity and detection accuracy, it is currently the most practical monitoring program to prevent mobile phones from being brought into.In order to ensure the security of classified information, a cell phone jammer should also be placed in the classified area to block the communication of mobile terminals that are intentionally or unintentionally brought into the classified area.It is understood that cell phone signal blockers on the market can limit cell phone signals to 500 meters away from the launching station. The shielding radius is adjustable, and the coverage area reaches more than 30 square meters. The scanning speed will cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, causing the mobile phone to fail to establish a connection with the base station. Mobile phones appear to search the network, no signal, no service system, etc.The mobile phone signal shielding device can only shield mobile phone signals and does not affect other electronic equipment. Save energy, the power is 12W-480W. During operation, the shield scans from the low end to the high end of the forward channel at a certain speed.

The scanning signal generated by the signal generator passes the inverter, enters the oscillator and modulates it to the mobile communication working frequency band, and then is amplified by the power amplifier and the voltage regulator tube controls the power. The amplified frequency sweep signal is transmitted into the air in the form of radio waves. Because the frequency sweep signal...
