The Justice Department is promoting the upgrade of a new generation of jammers

The new SEAL goalkeeper François Bayrou (François Bayrou) advocated the installation of cell phone signal jammer to prevent the use of cell phones in prisons. This technology has established itself in a number of facilities and has been tested many times. It has many advantages and many disadvantages. "I am in favor of bringing the saboteurs to justice. Like Christiane Taubira and other Justice Ministers in 2015, the new seal guardian François Bayrou was featured on BFMTV and RMC responded to the phenomenon of cell phones in prisons. Photos of superiors posted on social media networks , Selfies of prisoners in swimming pools, photos of smoking marijuana ... Although the authorities have tried to curb this practice, the problem has existed for several years.

Since 2002 this law has allowed GSM signal jammers to be installed in prisons. You can prevent cellular frequencies from entering certain areas, while more expensive models interfere with larger areas. The briefcase-sized devices sold by the company can cover a radius of around 150 meters, while the basement-sized model can hold the conference room without a signal. According to our information, there are currently 804 devices in French prisons. Problem: Compared to the development of cell phones, this technology is usually out of date. The Ministry of Justice plans to invest 3 million euros to modernize the procurement of a new generation of telephone jammers. But there is a condition. According to a study in January, NTIA researchers installed a GPS jammer car in the storage room next to the 13 x 8 foot storage room on the first floor of the storage room. This study claims that it successfully blocked cell phone transmissions in the commercial frequency band between 700 and 2170 MHz, but if monitored from 6.10 m and 30 m from the phone, it will not interfere with commercial transmissions. However, according to NTIA, more research is needed to determine if the technology poses a potential threat to commercially licensed wireless services outside the prison walls. There are still some obstacles.
