Contraband phones are a real problem. They allow prisoners to handle drugs secretly, run illegal businesses and even organize murders, under the supervision of guards and warden. A prison in South Carolina recently discovered 35,000 cell phone calls and text messages in 23 days. For the prison authorities, this is undoubtedly a terrible fact.
This is why FCC Commissioner Ajit Pai and South Carolina Governor Nikki Haley are pushing to cut off prisoners’ access to mobile phones. Prisoners are allowed to make calls, but only on special fixed-line telephones monitored by law enforcement agencies.
What happens to the cell phone in the prison?
The cell phone owned by the prisoner allows him to contact external partners in the crime to coordinate escape plans, thereby creating a life-threatening situation for the agency’s guards and the public. More commonly, reports from correctional facilities indicate that the overwhelming majority of hidden mobile phones were used to harass victims of their crimes, or that a prisoner repeatedly intimidated his victims to persuade the victim to abandon the charges or change him The story to instill suspicion testimony.
Many detainees continue to organize illegal drug trade from within the prison walls. Mobile phones are an important means for detainees to keep drug organizations running and tightly controlled. By contacting visitors before they arrive, prisoners can arrange for the transfer of drugs and drug paraphernalia, allowing them to continue the illegal habits of being detained. The family is often harassed by relatives who have been imprisoned, and when the family realizes that their relatives receive better services during detention, they ask for bail.
Rosenstein cited preliminary reports that the Federal Bureau of Prisons housed 185,000 prisoners and confiscated more than 5,000 cell phones from prisoners in 2016, but this number increased last year. The deputy prime minister said his office recently prosecuted a Tennessee prisoner who used a smuggled cell phone to download and send child pornography and another North Carolina gang member used a cell phone to order an attack on the prosecutor’s father.
Mobile phone detection jammer perfectly solves the problem of prison mobile phone
The prison department installed two mobile phone detection shields in the central prison to prevent high-risk prisoners from using mobile phones smuggled into the prison to contact their accomplices.
Because the coverage area of the mobile phone detection shield is 500 square meters. It will prevent the phone from making or receiving calls. It prevents gangsters and criminals from keeping in touch with their colleagues in order to carry out activities outside.
The GSM jammer needs to be destructive only on the downlink side of the cellular receiver and generate a carrier frequency band strong enough to prevent the cellular phone from logging into the data channel. This may mean that no external antenna is required, which limits potential interference to most neighboring cell sites. Separate rules can be considered to restrict or prohibit the facility's authority to own and operate interfering devices because of the presence of adjacent cell sites. Potential interference can be further controlled by using leaky coaxial cables instead of distributed antenna systems.
