Can the car wireless signal jammer realize long-distance wireless remote control?
After the high-power wireless signal jammer is modified and assembled by the vehicle, it becomes a set of vehicle-mounted special equipment that can be quickly transferred, deployed and used with the vehicle as the transport carrier. Customers who have used experience know that the main unit of the wireless signal jammer is installed at the rear of the vehicle, the transmitting antenna is installed on the top of the vehicle, and a control handle with a cable connection is generally installed near the driver's seat. or the controller. So some customers asked this question: Can the car wireless signal jammer realize long-distance wireless remote control?
The customer has such questions and ideas. The original intention is that the operator of the vehicle-mounted shielding device does not need to be in the vehicle all the time when it is necessary to open, close or set the wireless signal jammer. This is because the controller of the device is connected through the control wire. The cable is connected to the main unit of the device and has a limited length. What the operator wants is to remotely control the shielding device on the vehicle through a remote control-like manner at a location far away from the vehicle.
The unfortunate result is that the existing commonly used remote control or remote control methods cannot currently meet the needs of customers. The reason is actually very simple: the commonly used remote control methods now transmit control commands by wireless communication. Whether it is the receiving end or the transmitting end, data communication will be carried out at a relatively fixed wireless frequency or frequency band. These frequencies or Frequency bands, the most common ones are: 433MHz, 2.4G and 5.8G, then the embarrassing reality emerges: what does our car wireless signal jammer do? Its function is to shield wireless signals, which of course includes the most basic and common frequencies and frequency bands used for remote control signal transmission.
If the technology of wireless remote control is forcibly used as the control method of the vehicle wireless signal jammer, the following results will occur: the operator uses the remote control at a long distance from the vehicle shielding device, and there is no problem in remotely opening the device, but as long as It is the shielding device that is working normally. Because the emitted shielding signal will immediately shield the signal of the remote control frequency band, no matter how the operator uses the remote control, it will no longer be able to form an effective form with the remote control receiving end of the wireless signal shielding device. Communication, it is naturally impossible to achieve remote shutdown, and it is impossible to set and modify other functions or parameters of the shielding device.
