How does the on-board frequency jammer work effectively

How does the on-board frequency jammer work effectively

  • 2022/04/06
Many users who use the on-board frequency jammer do not understand its working principle. When using it, it often exceeds the frequency range, resulting in poor use effect.

The formation of mobile communication is that in a specific frequency range, wireless devices (mobile phones, etc.) and base stations are connected through radio waves to complete the transmission of data and sound with a specific baud rate and a specific modulation mode. When the mobile phone communicates, it contacts the base station through the uplink frequency, and then transfers the signal to the mobile service switching center to realize call or data connection. When the mobile phone is on standby, first, the mobile phone sends a signal to the base station to register and access the network, so as to get in touch between the mobile phone and the base station. Once the mobile phone call demand is displayed, it will be allocated to the mobile phone service channel according to the actual situation of the channel near the mobile phone, so as to make the mobile phone jump to the service channel and complete the call and data transmission. At the same time, wireless communication must ensure sufficient signal-to-noise ratio in order to complete reception and effective communication.

Therefore, when the on-board frequency jammer has a certain transmission power, the field strength in the interference area affects the interference range. No matter how high-power the on-board frequency jammer is, as long as the transmission power is a fixed value, the interference signal strength of the on-board frequency jammer will gradually decline with the increase of distance, thus losing its interference ability. This is the reason why the interference range of on-board frequency jammer is also different under the environment of different signal field strength. Nanjing Baikang Electromechanical Technology Co., Ltd., a manufacturer specializing in the production of vehicle frequency jammer, can customize the scheme according to your needs.
