Use your mobile phone wisely and do not always look at your mobile phone, which is very beneficial for our own safety and the public safety. If necessary, we must carry a portable cell phone signal jammer in order to intercept the cell phone signal in our vicinity and to achieve the purpose of shielding the cell phone. At the same time, a portable GPS jammer can be placed in the car to track and protect our personal safety.

Basically, it is a wireless jammer that overwhelms the radio or cannot communicate with the operator. When the drone flies autonomously, the cannon blocks the GPS signal that it relies on. The technology has been successfully tested in a military environment, but has not yet been used for civil purposes.

Although current director Gladwin Samuels said yesterday that the cell phone jammer was installed at Camp Street Prison prior to the July 9 fire and escape, but was stopped due to certain issues. Use them.

“There is a reason these signal blocker were originally installed ... we need to take steps to avoid using them. I cannot disclose them here but before the fire started these jammers were installed at Camp Street Prison but the setbacks mean they are not in use, ”he said at a press conference yesterday, answering questions about the prisoners' continued possession of cell phones and their frequent use of social media.

A prison jamming system works like other cell phone jammers, but there is a little twist. The smart jail jammer not only blocks unwanted calls in jail, it also only allows authorized calls. It is mainly used in prison cells, military facilities, and courthouses.
