Can a mobile phone signal jammer be remotely controlled by a remote control?
People who are familiar with cell phone jammer products will find such a phenomenon. Although it has been developed for about 20 years, it is rare to see the use of remote control to control the switch of mobile phone jammers. In the 2G and 3G era more than a decade ago, a few models were occasionally seen using remote control switches, but in the past ten years, almost no shielding equipment has been found to have remote control switch functions. So the question is, why does the switch of the mobile phone jammer not use the most common remote control switch method?
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 forced to do so. Because using the remote control to turn on and off the machine will cause the switch function to be unstable and unreliable. In the end, the manufacturer can only give up the control method of using the remote control.
There are two main types of commonly used remote controls 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 TV remote controls, but this method is characterized by a short remote control distance and no obstacles in the middle, otherwise it will cause remote control failure even at a short distance. However, in actual use, mobile phone signal jammers are often installed in relatively hidden locations, and sometimes obstructing 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 has a significantly greater remote control distance than infrared remote control, and common obstacles will not have much impact on the performance of the remote control, but the key point is that our mobile phone signal jammer itself will affect the wireless remote control.
The wireless frequency used by the remote control is mostly 433MHz remote control frequency, and WIFI 2.4G or 5.8G is also used as a remote control switch, but the current mobile phone jammer itself requires effective shielding for these wireless frequency bands, which will produce an interesting but very embarrassing ending: the user can turn on the mobile phone jammer normally through the remote control, but as long as the shielding device is turned on and working normally, it will continue to shield the communication frequency of the remote control. If the user wants to use the remote control to turn off the mobile phone jammer, it will be very difficult, unless the remote control is close to the shielding device host.
