As the phenomenon of prisoners using mobile phones to continue to manipulate crime spreads around the world, Argentina's Santa Fe Province has taken new measures to introduce cell phone jammers in Pinheiro Prison No. 11 near Rosario. cell phone jammer This move is considered an important means to reduce the connection between prisons and external crimes and is aimed at responding to the increasing number of shootings in Rosario.

　　Rosario's security crisis

　　In recent years, Rosario's security situation has become increasingly severe, with frequent shootings, and many violent incidents are related to the command of prisoners in prison.

　　In response to this problem, the Santa Fe Provincial Government decided to install a new cell phone signal jammer system in Pinheiro Prison to cut off prisoners' communication with the outside world.signal jammer

　　How the jammer works

　　The newly installed signal jammer system consists of eight devices that transmit jamming signals through antennas, blocking the phone from connecting to external communication networks. In short, prisoners using mobile phones inside the prison will not be able to connect to any communication network and will be "offline".

　　According to Claudio Briloni, Santa Fe's Secretary of Security, the system is designed to ensure that communications inside the prison are strictly controlled, with limited contact with the outside world only through fixed telephone lines. This method of communication will effectively reduce the chances of prisoners directing external crimes, thereby reducing the violent crime rate in Rosario.

　　Technical challenges and adjustments

　　Although the introduction of this system is seen as an important step in the fight against crime, there are still some technical challenges in its actual operation. For example, the installation and testing phases of the system required several adjustments to ensure that the jamming signals were limited to the prison and did not spread outside the prison and affect the communications of innocent citizens.

　　The experts responsible for setting up the system pointed out that the installation positions of the antennas have been strategically arranged to cover the security perimeter of the prison while avoiding interference with the signals in the surrounding areas. At present, the system is in its initial stages and will continue to undergo different tests and calibrations in the future.
