In order to prevent the illegal use of cell phones, 21 third generation (3G) jammers have been installed in 10 sub-prisons of the Tihar prison complex; Abhishek Sharan reports.
Prison sources said the new jammers using 3G electromagnetic signals and the 11 jammers created in recent years should improve the prison's ability to block mobile communications.
The source said, "3G jammers will improve our capabilities, as early wifi jammer can only prevent communications using second generation signals." The source said second-generation (2G) jammers can only block up to 50 meters. Mobile calls are vulnerable to attacks from upgraded 3G technologies.
The Delhi High Court instructed authorities in July last year to set up 21 jammers in Tihar to check cell phone use.
The source said 3G jammers were installed with wires designed to "prevent tampering." The price of each 3G jammer is around Rs.
Tihar spokesman Sunil Gupta said: "The installation of 21 new types of 3G jammers will make it impossible for prisoners to use their cell phones and discourage their smuggling of cell phones," Gupta said.
The increase in the number of mobile phone jammers will strengthen the prison's ability to prevent regular suspects (powerful criminals) from using cell phones. “The 21 disruptors will be located near cells and high security quarters 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 offenders usually try to obey prison rules.
Each high-security district accommodates prisoners who have committed serious crimes such as sedition, terrorism, organized crime and drugs. Among them is the condemned man of the 2001 parliamentary attack, Mohammed Afzal Guru (Mohammed Afzal Guru).
