In response to the challenge of gang members using mobile phones to engage in illegal activities in prisons, the Punjab jail department is testing portable mobile phone jammers to improve control over prisoners' communications. signal jammerThe pilot project has been implemented first in Patiala Central Jail, aiming to block signals in specific areas to prevent mobile phones from being used for illegal operations. If the results are significant, these devices will be promoted to major jails across the state, further ensuring the safety management of prisons.cell phone jammer

Portable jammers help accurately block communications

　　The Punjab jail department, in collaboration with Bharat Sanchar Nigam Limited (BSNL), India's national telephone service provider, has selected Patiala Central Jail as the first pilot site. GPS jammer Compared with traditional large jammers, these portable devices have higher flexibility and accuracy, and can effectively block signals in specific barracks without interfering with communication networks outside the prison.Wifi jammer This means that authorities can deploy portable jammers as needed in areas where gang members are active to minimize their use of mobile phones to commit crimes.

　　PK Sinha, director of the prison department, said that the functions of these portable jammers are currently being demonstrated and tested. Preliminary evaluations show that these devices are not only low-cost, but can also more accurately lock on communication signals in a specific area, thereby avoiding affecting the normal lives of residents outside the prison. If the trial is successful, portable jammers will be promoted to other prisons across the state.

Limitations and challenges of traditional jammers

　　Punjab has previously installed large jammers in major prisons, but these devices have failed to effectively curb the abuse of prisoners' mobile phones due to various technical reasons. Traditional jammers are mainly designed for 2G signals, but now most prisoners use smartphones that support 4G or even 5G networks, making old devices almost ineffective. In addition, traditional jammers often interfere with communications in communities around prisons, resulting in constant complaints and forcing management to shut down these jammers.

　　In contrast, portable jammers, with their small size and flexible deployment, can effectively block specific target areas without interfering with surrounding areas. This not only reduces the cost of purchasing and maintaining equipment, but also improves the accuracy of signal shielding.

Moving problem prisoners to "no signal" areas

　　In addition to introducing portable jammers, the Punjab prison administration has also taken a new measure to move prisoners who repeatedly abuse their mobile phones to the "dead zone" of Bathinda prison - a closed area with no mobile phone signal at all. By cutting off these high-risk prisoners from the outside world, prison management hopes to reduce the possibility of criminal instructions being transmitted from the prison, thereby improving the overall security level.
