cell phone jammer are illegal in the United States, but that doesn't mean they aren't used. They are apparently becoming more common and are expected to spread quite a bit in the near future. The FCC says that using a whine is considered "theft" of radio waves because this spectrum has been assigned to a commercial entity. However, the author of the article wonders whether it is "passive jamming" - such as erecting buildings made of material that blocks cell phone signals. While some may not like the idea of ​​having their signals blocked - others think that if they only have areas to "separate" it could become much more popular in the future. The article points to the rise of camera phones as a bottom-up surveillance company as one reason why we need areas that have no signal. That doesn't make much sense to me, since anyone who uses a camera phone can still take the picture and upload it later when they are within range of a signal. Still, it will be interesting to see if anti-jamming equipment becomes popular. Most people have no idea if a jammer is being used because it looks like there is no service. This makes it very difficult to find out if someone is using a jammer and means that nobody gets caught with these things.

In real life, these places can use disruptors, and some of the interviews below are real quotes from US netizens.

I would like to have Handy wifi jammer on my car when I drive down the street. I'm tired of having drivers who are still on their phones while driving and are not careful on the road. I caught more drivers on my cell phone and dropped nearby. It would be nice if my car bothered this idiot cell phone driver to get attention ON THE ROAD. NY State is illegal to use a cell phone while driving. Hence SCREW FCC law, it's my safe drive down the street with my car without being hit by careless cell phone drivers.

I work in a high school discipline office. Repeated cell phone use during school makes up 1/2 of my student suspensions. 1st violation is imprisonment, 2nd violation is 1 day suspension, 3rd violation is 2 days suspension and so on. I would like to know if teachers can legally place a signal jammer / blocker in their classrooms. would this be considered passive blocking?

I totally agree with the opinion of the article. I think everyone in our daily lives needs a cell phone signal jammer. It is usually used where noises are prohibited or silence is needed for a moment, such as churches, mosques, libraries, cinemas, conference rooms and others. it can help us a lot. A friend of mine, who is a teacher, was once annoyed by his students typing short text messages during class, and later he bought a portable cell phone jammer, then all the students were confused that their cell phones could not receive any signals, even when it was most my friend said he bought it well online.
