Phone jammers were initially developed for by law enforcement and the military for security purpose. For example, terrorists frequently trigger bombs with cell phones, so cell phone jammer can prevent such kind of explosion. Also, cell phone jamming blockers are often used for the protection of those VIP people who are targeted by criminals‘ attacks. With the widespread of phone signal jammers, many companies also have begun enlisting mobile jammers to get rid of corporate espionage in places where radio transmissions are potentially dangerous.
There is an ongoing controversy about the legality of mobile phone jammers. It began with a Philadelphia man who tried private jamming on a city bus when he was regularly traveling. The man was finally subjected to heavy fines since there are restricted laws against using cell phone signal jamming blockers in the public places. There are many reasons why using these cell phone jammers is illegal and the government has recently put out a release outlining these reasons, the primary reason being public safety. Because cell phone jammers block incoming and outgoing calls, it means that an ill-timed jam could limit people’s ability to call emergency services or report crimes since the phone signal jammers do not distinguish between social or other cell phone conversations and an emergency call to a family member or an emergency responder. So the government officers believe that the phone jamming devices create serious safety risks. In all, they believe that the wide spread cell phone jammers seriously affected the normal order of wireless communication. Another reason why the phone jammer is illegal is that it constitutes theft. According to the operating principle of phone jammer, cell phones operate on radio waves, and cell providers have paid the a lot of money to have exclusive use of the frequency that they broadcast on. Cell phone jammers work by flooding the surrounding area with so many radio waves of the same frequency that your phone can’t tell what is coming from the telecom provider or your phone jamming device.
Well, since mobile jammer is illegal, if there is any other ways that can help us get rid of unexpected cell phones? The fact is that there are many legal ways that you can adopt to block cell phones. For example, you can place a thick steel plate between the cell phone and the associated tower. This will surely blocks the signal, but what you need is a huge thick steel plate. There are many other ways to stop phone signals, but they are definitely not portable.
So, it turns out that mobile phone signal jammer is the best and easiest way to block mobile phone signals. However, it is illegal for ordinary civilians to create private jamming. We do need many legal ways to help us staying away from the disturbances of unexpected cell phones.
