With the progress of science and technology, our life becomes more and more convenient. But the same thing can cause a lot of problems. It is necessary to have a device beyond the scope to cut off the phone signal as needed, so that wi-fi has the ability and power to disconnect at home. If necessary or necessary, the family cell jammer must be a choice. It will have less impact. This high performance WiFi shield has the output adjustment function. You can control one of the frequencies individually, choose to open/close, and control the range of interference signals.
When someone hears a mobile phone interference, you may get a negative overall impression. In the case of a simple cell phone jammer, you need a very large or powerful jammer. These places include places of worship, university lecture halls, libraries, concert halls, conference rooms and other quiet places.
The price of this product is very high, cheaper than similar products. Interference devices may interfere with all cell phone signals, such as 2G, 3G and 4G. It has stable GPS jamming performance. I am deeply loved and trusted by my clients.
