The technology used by cell phone jammer can help ensure the security of message content. If the jammer is found to be illegal, the government can also confiscate it. Although most countries/regions prohibit private citizens from installing jammers, some countries/regions have legalized the installation of jammers by businesses and government organizations. Netline is such a company that sold its first jammer in 1998. Since then, it has been developing its business globally. But it is not the only company that produces jammers. There are dozens of suppliers selling jammers on the Internet.
There are various types of mobile phone jammers, with different power sources and different types of functions. Some operate on batteries, while others use central systems. The signal jammer has a voltage controlled oscillator to generate the signal and RF amplification to enhance the power of the signal. These are usually small portable devices plugged into wall sockets or powered by batteries. These devices are designed to block all mobile phone signals within a 100 foot radius.
They can be used in many places, including classrooms, theaters, vehicles, and even on quiet trains. Although making a phone call is convenient, it can cause interference and potential danger. Mobile phone blockers can be used in various situations, from public transportation to prisons. For example, a gang member in Philadelphia used his phone to organize the murder of his opponent.
There are various reasons for service interruption. The jammer may unintentionally interfere with the signals of other phones, or even interfere with a person's privacy.
Jammers can block calls and even GPS signals. You need to be close to your phone in order for it to function properly. It is important to ensure that the jammer is installed in areas where phone signals are common.
The FCC has not yet issued a clear policy on mobile phone jammers. If the use of jammers is prohibited in your area, and if the FCC does not change the law in the future, you may need to reconsider operating the jammer.
