People who know about wireless jammer products will find such a phenomenon. Although it has been developed for about 20 years, in terms of the switching mode of wireless jammers, it is rare to see that the switch is controlled by a remote control. In the 2G and 3G era more than ten years ago, a few models could occasionally be seen using remote control switches, but in the past ten years, almost no shielding device has the function of remote control switch. So the question is, why not use the most common remote control switch for the wireless jammer switch?

The answer to the question is: it is not that the manufacturer does not want to use the remote control for switch control, but it is a last resort. Because the operation of starting and shutting down with the remote controller will cause the switch function to be unstable and unreliable. In the end, it can only be that the manufacturer has to give up the control method of using the remote controller.

There are two types of remote controllers commonly used now. The first type is infrared remote control, and the second type is wireless remote control.

Among them, the infrared remote control method is most commonly used on the remote control of the TV, but this method is characterized by a short remote control distance and no obstacles in the middle, otherwise the remote control will fail even at a short distance. However, in actual use, wireless jammers are often installed in relatively hidden locations, and sometimes blocking objects are placed in front of them, which will seriously weaken the remote control switch performance of the remote control.

The second type of wireless remote control, its remote control distance will be significantly greater than the form of infrared remote control, common obstacles will not have much impact on the performance of the remote control, but the key point is that our wireless jammer itself will affect the wireless remote control. The wireless frequency used by the remote control is mostly 433MHz remote control frequency point, and some use WIFI2.4G or 5.8G as the remote control switch, but the current wireless jammer itself requires effective shielding for these wireless frequency bands. There will be an interesting but very embarrassing ending: the user can turn on the wireless jammer normally through the remote control, but as long as the shielding device is turned on and working normally, it will continue to block the communication frequency of the remote control. If the user wants to use the remote control It will be very difficult to turn off the wireless jammer, unless the remote control is close to the host of the shielding device.
