Problems solved by technology

The trunked vehicle communication system integrates a number of radio stations with different frequency bands and functions. Due to the limitation of the antenna's active transceiver function, these devices cannot adopt traditional suppression measures such as shielding and filtering; More and more dense, different types of interference such as adjacent channels, harmonics, intermodulation, intermediate frequency and mirror frequency between wireless systems will inevitably lead to the existence of some frequency self-interference bad points that affect each other in the system, resulting in the radio communication distance Shortening, poor voice quality, increased noise and other consequences, in severe cases, will lead to complete blockage of each communication channel, resulting in the paralysis of the trunked vehicle communication system or even the entire system

The main reason for the above problems is that the electromagnetic compatibility of the system is not considered when the frequency is assigned to the top-mounted equipment of the trunking vehicle communication system
