Mobile phones are aimed at the information age. It is an important communication device and entertainment device. However, there are certain rules for using mobile phones. Not all of these tools can be used anywhere. For example, calling at a gas station is prohibited. Mobile phones are convenient and flexible, and are widely used in people’s work and life. Mobile communication is the transmission of voice and data information in an open electronic communication system. As long as there is a corresponding receiving device, it can intercept anyone’s call information anytime, anywhere. Every phone can make calls. The gps interference power of the signal masker is fixed, and the shielding radius of the non-blocking space is determined by the path attenuation and the signal level of the receiving base station. In order to achieve the interference of the mobile phone signal jammer on the mobile network, it is necessary to ensure that the signal field emitted by the jammer is stronger than that of the mobile signal in the interference area. The closer the interference location is to the base station, the stronger the field strength and the smaller the effective interference area. The farther the interference location is from the base station, the weaker the field strength and the larger the effective interference area.
The GPS blocking program is specifically used to disable GPS interception signals. The portable jammer can be used to block various GPS tracking devices and block satellite tracking communications. It should be noted that GPS jammers will not interfere with cell phone signals. This type of retarder is small and light, which is very easy to carry. In addition, you can use an external battery as a power source or car power supply.
With the rapid development of technology, the functions of mobile phones are also advancing rapidly, especially the latest 4G mobile phone signals, which provide a lot of help and convenience for our lives! At the same time, it will bring trouble to our lives. The impact of noise and privacy on mobile phones is not well protected, which confuses us. The best solution is cell phone signal interference equipment. There is now a hand-held jammer, which is particularly suitable for protecting different signals from mobile phones from 5 frequency bands. They can simultaneously block the use of WiFi 3G GSM and Bluetooth mobile phones, especially without WiFi and Bluetooth cables. Both 2020 and the next few years are very popular.
