The wireless transceiver module is used in electronic equipment toy control, industrial control, wireless remote control, and other industries. When the remote control transmits and sends data, the wireless transceiver module receives the data and translates the data through the microcontroller, and then controls the relay to disconnect or combine to realize the forward rotation of the motor. /Reverse, accelerate/decelerate, and other functions. During this process, the inner coil of the motor will generate many kinds of electromagnetic interference, and the distance during remote control cannot meet the customer's requirements. In order to reduce the influence of electromagnetic interference, it is necessary to choose a wireless transceiver module with a wifi jammer, which has strong anti-electromagnetic interference characteristics. Next, what is the function of the wifi signal jammer of the wireless transceiver module, and what is the principle?
The role of shielding cover: A shielding cover that is combined with a metal bracket and a metal cover to play a shielding role is welded above many components of the main board of mobile phones, GPS, and wireless module electronic products. At present, there are many integrated shielding covers used on wireless transceiver modules, which are simple and cost-effective, and shield static electricity on the PCB board to protect electronic components.
The principle of jamming cover: use a shield to surround the interference source of components, circuits, assemblies, cables, or the entire system to prevent the interference electromagnetic field from spreading outward; use a shield to surround the receiving circuit, equipment, or system to prevent them from being affected The influence of external electromagnetic fields.

In order to increase the wireless control distance, simply pursuing high sensitivity or increasing the transmit power of the transmitter cannot completely increase the control distance, because, in practical applications, there will be factors such as power supply, electromagnetic interference in the working environment, or power supply ripple interference. Therefore, it is necessary to comprehensively Consider various anti-jamming capabilities of the RF receiver.
