In order to combat the continued criminal activities of prisoners through contraband mobile phones, the Indian government has stepped up its efforts to deploy jammers in prisons in recent years. In January this year, the Parappana Agrahara Central Prison in Bangalore installed the latest jammer system, T-HCBS, to replace the old equipment. signal jammerThe move is intended to curb illegal communications in prisons, but its wide signal blocking range has also had a negative impact on the surrounding communities.cell phone jammer

　　Residents report: Communication disruption affects life

　　Residents of the community surrounding the Bangalore prison soon found that their daily communications were being disrupted. GPS jammerResidents living within 500 meters of the prison reported that mobile phone signals were severely limited, calls could not be connected, and even sending and receiving text messages became a problem. For many families, the rhythm of life was completely disrupted. For example, when resident Akash Sharma's child suddenly fell ill at school, the school tried to contact his parents but failed. This experience made Sharma question the widespread use of jammers.Wifi jammer

　　In addition to affecting emergency communications, the presence of jammers has also had a serious impact on the e-commerce and food delivery services that modern society relies on. Residents were unable to receive OTPs, resulting in bank transactions not being completed, while delivery agents were unable to contact customers, causing repeated delays in the delivery of items.drone jammer

　　Prison authorities' stance and response

　　In the face of public dissatisfaction, prison officials stressed that the installation of the T-HCBS system was a necessary measure approved by the government. Malini Krishnamoorthy, director general of prisons, said they had tried to adjust the signal strength of the jammer to reduce interference to surrounding residents. However, reducing the intensity of interference also means that security inside the prison may be affected, and prisoners may once again engage in illegal activities through their mobile phones.
