Signal Jammer FAQ

how far can a signal blocker jamming?

The range that can be shielded depends on the power of the signal scrambler and the surrounding environment and signal strength. For example, the presence of walls and wood will affect the transmission distance of the signal jammer. Low-power radio jammer can shield a radius of about 1-10 meters. Circle range, if conditions are ideal, high-power jamming device can even block areas with a radius of more than 100 meters.

With the development of science and technology, the current signal jammer is very convenient to use. It only needs you to turn on the switch and open the signal frequency band you want to shield. After 2-5s, the signal shielding can be completed. It can only block the mobile phone signal and Do not block WiFi signals , only interfere with the frequency you want to interfere without affecting the use of other smart technology devices.

Now the signal frequency bands of smart devices are as high as dozens or even hundreds, and the signal frequency bands of each device are different. If you want to block the communication signals of all frequency bands, only military jammers can achieve this effect, but if we use them in our daily life There is absolutely no need to block signals in all frequency bands, just block the most important signal frequency bands.

Of course, we can also customize the signal frequency band you want to block without extra charge.

A signal jammer is a device used to interfere with radio frequencies. It can emit high-frequency signals that interfere with the normal operation of other radio equipment.In order to apply to different usage scenarios, Signal blocker derives a variety of different types:, including fixed, adjustable, and programmable. The signal frequency output by fixed jammers is fixed, while adjustable and programmable jammers can adapt to different jamming needs by adjusting the frequency or amplitude.What is the blocking principle of signal scrambler?The principle of the jamming device is to interfere with the normal operation of other equipment by sending out high-frequency signals. These signals are usually emitted in a specific frequency band, usually the radio frequency band. They can be emitted at a fixed frequency, a changing frequency, or a random frequency.Application scenarios of jammer signal blockerSignal Disruptor have a wide range of applications, it can be used for a variety of purposes, including protecting classified information, preventing radios from being snooped or tracked, or jamming the signals of other radios. They can be used in government, military, business or personal fields.but they can also cause interference with the normal use of radio equipment. Therefore when using a signal jammer, you need to pay attention to the surrounding environment to avoid interfering with irrelevant equipment or causing unnecessary interference.Signal jammer is a useful radio device that can be used for a variety of purposes. However, due to their special nature, care needs to be taken when using them to ensure that they do not cause unnecessary interference to radio communications.

Jamming with a mobile phone is like interfering with any other type of radio communication. A mobile phone communicates with its service network through a base station. As cell phone users drive down the street, the cell signal switches from one base station to another.

We know that radio communication uses electromagnetic waves to communicate. The functional properties of electromagnetic waves are determined by their frequency. Our mobile phones must emit qualified electromagnetic waves in order to connect to our telecommunications carrier base stations. Different communication systems use different frequencies, so that everyone is safe and does not interfere with each other.

The phone signal jammer emit the same radio frequency signal as the cell phone signal. Since the frequencies are the same, the cell phone cannot tell which signal is a regular base station signal, thus "jamming". As long as there is a machine on the same frequency as the phone, the base station will make a lot of "noise" when it tries to connect to the phone. You will find that the signal from the phone is unrecognizable, so you will refuse to communicate with the phone.

In the early days, jammers only blocked one set of frequencies, such as 2G, while sophisticated jammer device can block several types of networks at the same time, such as 2-3-4G.

Actually simple. That is, the jamming disruptor bands corresponding to these three signals are repeated in a cyclic manner, covering these three jamming bands at the same time, and the interval of this cycle is so small that the mobile phone has no chance to speak and can only sit down. Covering 2/3/4G, what about bluetooth and wifi? It doesn't matter, the same can be done. The frequency jammer has evolved again, adding the frequency bands of bluetooth and wifi to the scanning range, so that several common communication methods in the society are completely covered.

Many people do not understand the difference between Bluetooth, Wi-Fi and mobile data. They seem to be wireless communication technologies. In fact, the main difference between them is the frequency band. In mobile communication technology, 2G mainly works in the 900-1700MHz band, 3G works in the 1900-2100MHz band, and 4G works in the 2300-2500MHz band. Bluetooth and WiFi work at 2.4GHz.
