　　1. The connection between crime and mobile phone communications

　　In Rosario, drug lords in prisons use mobile phones to command criminal actions outside, especially shootings. According to the Santa Fe Prosecutor's Office, eight of the ten shootings in March 2023 were ordered from prison. For example, the supermarket owned by Messi's father-in-law was shot, and the order was issued from a mobile phone in prison. Similar incidents are common, exposing the seriousness of illegal communications in prisons.

　　Not only that, the police report pointed out that 70% of the instructions for the 288 homicides in Rosario in 2022 came from prison. Drug lords use mobile phones to keep in touch with the outside world and organize criminal gangs to intimidate, extort and murder. Such rampant criminal activities have prompted the government to realize the importance of cutting off communications inside and outside the prison and began to seek technical means to curb this phenomenon.

　　2. Technical principles and applications of mobile phone jammers

　　The newly installed mobile phone jammer system uses eight strategically located antennas to block mobile phones from connecting to external networks by transmitting jamming signals. These antennas work in a directional manner to ensure that the jamming signals only affect the inside of the prison and do not affect the outside areas of the prison. This precise directional jamming technology is designed to avoid interfering with the normal communications of residents outside or nearby facilities.

　　Developed by Invap, a leading Argentine technology company, the system is based on an advanced Israeli platform and is specifically designed to block 4G communications. In the future, with the application of 5G technology, the system will be further upgraded to meet the challenges brought by the new generation of network communications. This technology not only limits the illegal communications of prisoners, but also greatly improves the security of prisons.

　　3. The necessity of installing jammers

　　The installation of the jammers reflects the determination of the Santa Fe Province to deal with increasingly complex criminal activities. In recent years, the crime problem in Rosario has become increasingly serious. Drug lords in prisons freely direct external criminal actions through mobile phones, which has worsened the city's security situation. After realizing this problem, the government decided to take measures to cut off criminals from the outside world.
