This discovery shocked everyone present and the two policemen who escorted him were arrested. These incidents highlight the management loopholes and corruption in the prisons.

Installing jammers: A new strategy to block 5G communications

　　In order to solve the problem of illegal communications in prisons, the government has decided to introduce more advanced jammer technology. According to a statement by Home Minister Jnanendra, the new mobile phone jammers to be installed in Parappana Agrahara Prison can not only block traditional 2G and 3G signals, but also intercept 4G and 5G network calls. Compared with previous jammers, this new device has stronger signal blocking capabilities and can effectively curb prisoners from using instant messaging applications such as WhatsApp and Telegram for illegal activities.

Therefore, when deploying jammers, the government needs to conduct multiple tests and adjustments to ensure the security and stability of the system.

　　In addition, the Karnataka government plans to promote this jammer system to other prisons and gradually establish a prison communication protection network across the state. In the future, this technology is expected to become an important means to combat illegal activities in prisons, thereby improving the security management level of the entire prison system.
