It is very necessary to use jammers in prison

Oklahoma City-Thousands of illegal cell phones eventually fell into the hands of prisoners using criminal tools. However, prison officials said on Monday that they were banned from using one of the best ways to prevent such cell phone jammers. Oklahoma and South Carolina prison officials testified before the Oklahoma Senate Committee to prove the effectiveness of cell phone jamming technology. Federal law prohibits government agencies from using this technology, and the mobile phone industry refuses to do so.

Last year, Oklahoma seized more than 5,200 smuggled cell phones from prisoners. Mike Carpenter, head of security at the Oklahoma State Department of Corrections, said that although there was a reduction of about 7,500 compared to a year ago, the problem is still a serious one. Carpenter said that in the past month, fighting between rival gangs in Oklahoma prisons has rapidly expanded through the use of prohibited cell phones in scuffles in several other prisons. One prisoner was killed and more than a dozen were injured.

Carpenter said: “I think (mobile phone) traffic congestion will work? Absolutely.” According to Gerard Keegan, a spokesman for the Cellular Telecommunications and Internet Association, the mobile phone industry opposes the use of cell phone portable jammer in prisons, mainly because Worried that it will also block legitimate users’ signals. He said that the organization is supporting a “management access” system that uses technology to determine which signals come from smuggling calls in the prison, so measures can be taken to disable these targeted calls. He said that the team also supports further testing of cell phone jamming technology.

According to the federal law that states may use jammers, it is still pending in the Senate and Senate. Oklahoma Senator James Lankford said earlier in the year before the US Senate: “My advice is simple.” “To protect our guards, protect our family and prevent Carrying out criminal activities in prisons allows us to block cell phones in prisons.” Last year, federal officials in a federal prison in Cumberland, Maryland tested micro-jammers and said that when the equipment is operating normally for about 6 meters , They can turn off the phone signal in the prison cell.
