Recently, I have frequently received some such inquiries: I want to buy a mobile phone jammer, which can be used in my family to interfere with the child's room signal. However, there are several special requirements for this mobile phone jammer:
1. The volume is required to be as small as possible, preferably the size of a mobile phone, which can be easily hidden;
2. The mobile phone jammer is required to be powered by battery when it is working, and it can be used continuously for at least 2-3 hours;
3. It is required to have the performance of transmission through the wall. It is best to be able to achieve that when the mobile phone jammer is turned on in the adjacent room, the interference signal can still pass through the wall, and it can continue to effectively interfere with the signal in the next room;
4. Precise range restrictions are required, for example, the signal interference can only be aimed at children's rooms, and must not affect other adjacent rooms or neighbors on the left and right, and neighbors on the upper and lower floors;
5. The price of mobile phone jammers is required to be absolutely cheap. If the unit price of a device exceeds a few hundred yuan, it will definitely not be able to buy;
6. It is required to be able to remotely control the startup and shutdown of the mobile phone jammer. For example, when parents work in other places, they can realize remote control through mobile phones and networks, and grasp the working status of the device and whether the room signal is interfered in real time;
Special requirements such as the above are more than that, and they will not be listed here. Looking at each of these requirements in detail, it is not difficult for our professional mobile phone jammer manufacturers. Any one of the requirements, or a combination of several requirements, we can fully realize or basically meet the requirements. The difficulty lies in , if these requirements are all concentrated on a cell phone jammer, it is impossible to do. Because these requirements are inherently contradictory and conflicting. It doesn't make sense in terms of technical principles and implementation methods.
We suggest that these parents should fully understand some basic common sense of electronic products, as well as the realization principle of technical means, and accept such Base price for high-tech products.
