There are many types of jammers

It’s easy to buy devices on the Internet that can disrupt wireless signals such as mobile phones, GPS signals, Wi-Fi systems, and more. The jammer works by covering the radio tape to be captured in a noisy area. Because they are inexpensive devices not approved by the Federal Communications Commission (FCC), they often emit noise in other frequency bands. U.S. cell bands are adjacent to the 800 MHz band where Nextel is deployed, some public safety, government and commercial systems, so these signals are likely to interfere with the target band.

gps jammer are used in schools, restaurants and other places where homeowners want to prevent people from making and receiving calls indoors. Recently, prisons are considering deploying jammers to prevent prisoners from using cell phones in prisons. It is illegal to own a mobile phone in prison, but again, this does not seem to prevent prisoners from owning a mobile phone.

Recently, many prisons have come together, asking the FCC to allow congestion within its walls, pending a verdict. There are many problems with this “solving” method, the most important of which is that the guards will not be able to use their cell phones, and if the prison radio frequency is near one of the cell phone groups, the cell phones will most likely not even be able to use the interphone. If paramedics, police or firefighters are called into the prison and their radio system is in the 800 MHz band, they are likely to lose their lives once they enter the gate of the prison. communication.

The real solution is to not allow jammers. Since most people don’t understand the consequences of installing a jammer, this may cause impulses to others, who believe that if a prisoner can use a jammer, they should be able to use it.

As a mobile phone user, I want to have the right to use my mobile phone almost anywhere. In unpopular places such as doctors’ offices, theaters, and some restaurants, a notice board is usually displayed to inform people who enter not to use cell phones indoors. Mel Samples, who runs a wireless consulting firm in Los Angeles, has worked closely with us for years to better connect with his use of cell phones in prison.
