It is true that there are many types of cell phone signal jammers on the market, so if you want to block any signal in a very large range, you will spend a lot of money on one of the devices. However, if your budget is tight and you can’t buy expensive jamming equipment, then you can buy one of these low-power devices. And their scope of work is very wide, especially if your main goal is to keep people from the surrounding area out. In this case, I think a practical range of about 5 meters is sufficient, especially when you use it on a bus and want people to be quiet for a few minutes. Then a mobile cell phone jammer like this will definitely come in handy. In addition, you need to pay special attention to the battery life of the portable/portable jammer, because if you don’t have a lot of money, this is the most important thing you should look for, as well as the interference frequency and range. Every jamming device is doing well and you It must be remembered that this is the easiest way to prevent people from using mobile phones to make calls. It is necessary to understand some basic knowledge of these shielding devices, so that you can easily make a choice when buying.
The story of the Chronos Sentinel project in the UK spreads on the Internet like a fire in timber storage. People are discussing this issue. In these heated debates, some people agree with GPS jammers and some people disagree, which is natural and normal. But governments of different countries are taking actions to deal with this situation. For example, the FCC is trying to figure out how to use various cell phone jammers in a controlled way so that citizens can use cell phone jammers to block annoying calls, but can call 911 in an emergency. on time. The FCC made this attempt. I am really surprised. I hope it will succeed, because despite this, this is just the beginning, but it is still very promising for me. But there is another opposite situation for tracking equipment manufacturers. They also learned about the use of cell phone jammers on the Internet and decided to go beyond cell phone jammers and create a new type of tracking device. This is an example of how they did it.
