Haryana Deploys Targeted Call-Blocking Tech in Prisons After Ambala Pilot
The state is replacing traditional jammers with the T-HCBC system to disrupt criminal networks without affecting nearby residents.
The Haryana government has launched a pilot project at Ambala Central Jail to implement a high-tech call-blocking system designed to eliminate the use of mobile phones by inmates. This strategic shift aims to harden prison security and prevent high-profile criminals from coordinating illegal activities from behind bars.
Ambala Central Jail was selected as the initial site for the installation of the Towers Harmonious Call Blocking System (T-HCBC). According to Jail Superintendent Amit Kumar, this technology differs fundamentally from the traditional jammers previously employed in correctional facilities. Unlike older systems that often caused indiscriminate signal loss for residents living near prison perimeters, the T-HCBC is designed to be more effective and targeted in its application.
The Struggle with Smuggling
Ambala Central Jail, one of India's oldest prisons spanning 60 acres, has historically been a flashpoint for security breaches. The facility has struggled with the persistent smuggling of mobile devices, with previous raids recovering dozens of phones, including high-end iPhones, from inmates. These devices have allowed "hard-core criminals" to maintain control over external networks, rendering traditional jamming technology insufficient to maintain total communication silence.
A Technical Upgrade in Security
The transition from broad-spectrum jammers to a dedicated call-blocking system represents a significant technical upgrade for the state's penal system. By moving away from blunt signal interference, the government can more precisely disrupt inmate communications without the collateral interference that plagued earlier efforts. This precision is critical for maintaining the integrity of the prison's security perimeter while minimizing the impact on the surrounding civilian infrastructure.
State-Wide Expansion
Following the pilot phase at Ambala, the Haryana government intends to replicate this technology across other jails in the state. The expansion plan includes the rollout of modern surveillance and security technology to facilities in Hisar, Faridabad, Kurukshetra, Kaithal, and Sirsa. The goal is to create a standardized, state-wide barrier against the use of unauthorized communication tools, effectively isolating criminal leadership from their operatives in the outside world. By integrating these systems, the state aims to close the security gaps that have historically allowed inmates to bypass traditional electronic countermeasures.
