The increase in the number of mobile jammers will strengthen the capacity of prisons

In order to prevent the illegal use of cell phones, 21 third generation (3G) jammers have been installed in the 10 sub-prisons of the Tihar prison complex. Abhishek Sharan reports.

According to prison sources, the new jammers using 3G electromagnetic signals and the 11 jammers manufactured in recent years are expected to improve the prison's ability to block mobile communications.

The source said: “3G jammers will improve our capabilities, as the first wifi jammers can only prevent the use of second generation signals for communication. The source said second-generation (2G) jammers can only block up to 50 meters away. Cell phones are vulnerable to attacks from enhanced 3G technology.

The Delhi High Court ordered authorities to set up 21 jammers in Tihar in July last year to check cell phone use.

The source said the GSM jammer was installed with wires designed to "prevent tampering." The price of each 3G gsm jammer is around Rs.

Tihar spokesman Sunil Gupta said, "The installation of 21 new types of 3G jammers will prevent prisoners from using cell phones and prevent cell phone smuggling," Gupta said.

The increase in the number of cell phone phone jammers will strengthen the ability of prisons to prevent ordinary suspects (capable criminals) from using cell phones. “The 21 saboteurs will be located near cells and high security areas to accommodate prisoners accused of serious crimes, including those related to terrorism and drug trafficking. Sources say they are more likely to try using cell phones.

First-time offenders usually try to obey prison rules.

Each high security zone accommodates prisoners who have committed serious crimes such as sedition, terrorism, organized crime and drugs. Among them, Mohammed Afzal Guru, condemned by parliament in 2001.
