Key features
Correctional facilities worldwide face persistent threats from mobile phones smuggled into prisons by visitors, staff, drones, and other covert methods. Once inside, these devices give inmates unrestricted communication capabilities, enabling them to bypass monitoring, coordinate criminal activities, intimidate witnesses, and manage operations both inside and outside the facility.
The rapid evolution of smartphones and 4G/5G networks makes this challenge increasingly complex. Encrypted apps, multi-band devices, and strong signals from external cell towers create an environment where traditional control measures are no longer effective. At the same time, prisons must ensure that security systems operate safely and do not interfere with authorized communications or surrounding public networks.
To address this, facilities require advanced, precisely engineered solutions that can detect, control, and neutralize unauthorized mobile activity while maintaining operational stability, regulatory compliance, and the safety of staff, inmates, and the public.
