Although recent news indicates that some prisoners sometimes use mobile phones to access the Internet, the Ministry of Justice has just announced that French prisons will use a new type of “high-tech” radar jammer. Your cost has not been specified. After the Charlie Hebdo attack and Manuel Valls’ announcement, Christiane Taubira yesterday announced the outline outline of the plan, entitled “Anti-Terrorism Justice” (PDF) . In the next three years, a total of 181 million euros will be released, of which 110 million euros will be released in 2015. Prison management will therefore benefit from 43 million euros of protection funds, part of which will be used. To “fill the disruptors of high-tech mobile phones.” However, Place Vendome has not yet provided a deployment plan.
We need to understand the purchase requirements of gsm jammers. For example, in addition to the gsm network, we also need to protect the signal type. Is it necessary to protect the frequency bands of 3G and 4G networks? In this way, we can buy a cell phone blocker that can intercept all cell phone signals. In addition, we have purchased electronic cell phone jammer equipment and must consider where to use it. Portable jammers can help us use indoors and outdoors, while desktop jammers use multiple antenna designs. As the name suggests, due to their larger interference radius and more types of signal shielding, they will be used not only for individuals, but also for prisons, courts and other larger places. .
Ordinary families can block radio waves in their daily environment. You have the right to avoid the inconvenience caused by mobile phones and other communication methods. It is great if you do not intervene in a malicious way. There is legitimacy. Bookstores and movie theaters hinder communication. This is a jammer that emits special radio waves to prevent communication. You can turn off this product to block radio waves and sound waves in a controlled environment. Turn off wireless communication. There will be communication during the review. You need to take some necessary measures. This makes it almost impossible to use high-quality communication. This is just one of the technical means for this. Some people think this violates the freedom of communication. It is important to use this GPS interference wave reasonably.
