To block the illegal use of mobile phones, 21 third-generation (3G) jammers have been installed in 10 sub-jails of the Tihar prison complex.

The new jammers using 3G electromagnetic signals, along with 11 existing ones set up over the last few years, are expected to enhance the prison's capability to block mobile communication, said a prison source.

“The 3G jammers will upgrade our capability since the earlier ones could only block communications using second-generation signals,” said the source. Second-generation (2G) jammers can block mobile conversations only up to 50 metres and are vulnerable against the upgraded 3G technology, the source said.

The Delhi High Court had last July directed the authorities to install 21 jammers in Tihar to check the use of mobile phones.

The 3G jammers have been fitted electrical wirings designed to “prevent tampering”, said the source. Each of the 3G jammers was bought for around Rs. 15 lakh.

Tihar spokesperson Sunil Gupta said, “The installation of 21 new 3G jammers will make it impossible for inmates to use the mobile phones and discourage attempts to smuggle them in, Gupta said.

The increase in the number of the jammers will increase the prison's capability to stop the alleged usual suspects — hardened criminals — from using mobile phones. “The 21 jammers will be located around high-security cells and wards that accommodate inmates charged for serious crimes, including those related to terror and narcotics trafficking. They are the ones more likely to make attempts to use mobiles,” said the source.

The first-time offenders usually try to obey prison rules,” claimed the source.

Each of the high-security wards house inmates charged with serious offences as sedition, terrorism, organised crime and narcotics. Among them is the 2001 Parliament attack case convict, Mohammed Afzal Guru.
