3G Technology in Prison
Inmates in state prisons in Jaipur, India have reportedly upgraded to 3G technology which makes it easier for them to stay connected via mobile phone to the outside world. The state jails have been using jammers to try to disrupt these mobile connections, but the jammers have failed to even detect 2G frequencies let alone 3G ones so they are not an ideal solution.
The frequent use of 3G cell phones in state prisons has become a focus of political pressure as so far the jails have failed to find effective ways of limiting this use. It has come to light that many prisoners were using video chat to coordinate criminal activities on the streets from their jail cells. The existing jammers cannot detect 3G frequencies without being upgraded via an attachment, and the state prisons are currently in talks with the supplier to find ways of improving their operations.
