Interference technology has developed, and prisoners’ efforts to smuggle equipment are also evolving. She said these tests could lead to more widespread use of jamming technology in prisons to fix prisoners' phones, which officials across the country call their number one security threat. This has become a thorny issue in prison management.
Although prisons and prisons try to block mobile phones with sophisticated metal detectors, prisoners still try to smuggle them. Experts say that the only way for prisoners to use them for criminal activities is to interfere with the technology via mobile phones.
The prison GSM jammer has become a necessary supplement to the tool library needed to protect prisoners. Mobile phones are getting smaller every day, which makes it easier for prisoners to smuggle into the facility. This is a more difficult job for correctional workers who are already burdened, but cell phone jammers are the answer to restrict prisoners' use of cell phones for potentially dangerous activities.
The Federal Bureau of Prisons (BOP), in cooperation with the National Telecommunications and Information Administration (NTIA) and the Federal Communications Commission, conducted a micro-interference technology test at the Federal Correctional Institution in Cumberland, Maryland. Tests are conducted to determine whether micro-interference can prevent prisoners from using prohibited devices at the level of a single battery housing unit for wireless communication.
NTIA conducted an independent evaluation of micro-interference technology to determine its efficacy and potential interference in radio frequency communications. BOP and NTIA will review the data and analysis results of the BOP and NTIA tests, and formulate recommendations for strategic planning and possible acquisitions.
Next week, the department will begin testing a "micro-interference" system to assess whether this technology can be used to stop prisoners’ calls without disrupting services in the surrounding area, including those used by first responders.
It is difficult to stop the phone. Rosenstein said: "Mobile phone detectors also need to be introduced into prisons. There is also a mobile phone detection and positioning system, which can accurately detect the location of the phone and play an important role in the work of the prison." He added, The Department of Justice supports regulatory changes that will make it easier to deploy interception technology and cell phone jammer.
According to a statement, the Federal Bureau of Prisons tested "micro-interference" technology at the Cumberland Federal Correctional Institution. Officials want to test whether the system will block the equipment in a specific cell.
Like many countries, Canada has a prison contraband problem. Increasingly, its prisoners are sneaking on cell phones, so in order to prevent them from running criminal gangs from within, the country is considering using cell phone jammers in its correctional facilities.
According to documents obtained by the Main Board under the Information Acquisition Act, the Correctional Services of Canada investigated the use of mobile phone interference technology in March 2012. Previously, the agency reported that more than 200 illegal mobile phones were confiscated by federal prisons within three years.
