Phone jammers in jail trap residents near Bengaluru Central Prison in digital blackout

BENGALURU: Residents living near Bengaluru Central Prison at Parappana Agrahara are once again distressed due to the Tower Harmonics Call-Blocking System (T-HCBS) installed at the prison. Even residents using LAN (Local Area Network) WiFi are experiencing disruptions due to signal blockage from jammers over the past week.

Atish Bandyopadhyay, a software engineer and resident of Boston Block in Parappana Agrahara, opposite the prison, told TNIE that the prison department may have increased the amplitude of jammers, causing difficulties for residents in making WiFi calls.
