Lucknow: Following reports of cell phone use cases in prisons, Electronics India Limited (ECIL) was required to install 4G jammers in UP prisons.
Although jammers are installed in prison buildings in 75 counties across the state, they cannot block 4G networks and allow prisoners to use 4G-enabled mobile phones to run their criminal syndicates.
These GSM jammer were installed decades ago and successfully blocked the second-generation (2G) and third-generation (3G) networks, but could not restrict fourth-generation (4G) communications, which made it difficult for the prison department to monitor the activities of prisoners .
The prisoner was aware of the loophole and used the power outage and communicated with his assistants to order Supari to blackmail, rob, and even kill, because the disruptor would not resume operations until the power supply was restored.
