Introduction to the working principle of signal jammer
The signal jammer can use the same power to transmit signals to block mobile phones and other devices. After turning on the signal jammer, the signals of mobile phones and electronic devices in the area are interfered, which means that the signal interference in the area is successful. Cell phone users are becoming more and more popular these days, so cell phone jammers are more widely used than electronic devices to block the use of mobile signals in specific locations.
Mobile jammers are devices used to protect cellular phones from receiving signals. Moving the GSM modulator to the interfering device broadcasts a signal on the same frequency as the program. If you see your cell phone signal being stopped when you turn on a mobile jammer, you'll think the jamming is going smoothly.
A cellular phone is a duplex device and can use 2 frequencies at the same time. One is talking, the other is listening. Resolve signals simultaneously. The signal jammer only blocks one of the frequencies at a time, which results in both frequencies being blocked because the phone thinks there is no service in the area because it only gets one of them.
Interrupting mobile phones works similarly to how 3G interferes with other types of communication networks. In order for a cell phone to be used, a signal is sent from the cell phone to a cell tower. A city has several cellular towers. As a mobile user moves within an area, the signal is resolved from tower to tower.
Signal jammers push the same wireless network frequencies on your phone. Jammers cut off communications between mobile phones and the tower's base station. Jamming, also known as a denial-of-service attack, denies wireless signals to users in a specific area of the interfering device.
The principle of general signal jammer
There are different types of cell phone jammers currently on the market. Some devices block only one frequency, while others are able to block multiple types of Internet at the same time. The latter model can automatically switch from different networks to look for open signals. High-end devices can block all frequencies simultaneously, while others can automatically tune to specific frequencies.
Simply put, they transmit random static or noise within a common frequency range so powerfully that a nearby device cannot connect to the connection it is supposed to. Somewhat like being next to the engine of a sports car, opening the hood, while simultaneously trying to communicate with someone on the phone. The local noise became too strong, so the device was unable to connect. Rapidly covers a range of frequencies, effectively preventing equipment from functioning properly.
The frequency of the load wave that releases the electromagnetic induction interference signal is the same as the frequency of the load wave, so the negotiation (reduction) of the interference signal by the rice harvester and the power amplifier is used to collect the terminal equipment at the same time. It is like a fake (such as interference signal) transport vehicle and a real interference signal (such as) transport vehicle model (carrier communication frequency), the same appearance only the vehicle receives from the goods, the conclusion is that the fake goods are really delivered to the carrier Together. The electronic interference power is strong enough and is limited by the interference signal to complete the interference.
