Access management of cellular devices and other personal communications means is a prime target for various environments such as prisons and highly secured facilities. Through deep understanding of telecom RF, Septier has developed numerous products to support this requirement. Septier Cellular Firewall allows highly effective access management, selective jamming and service blocking for cellular devices. Used in secured compounds, by bomb disposal squads and special warfare teams, the cellular firewall enables tactical control of cellular devices, allowing authorized users to receive services while denying them from unauthorized devices. Septier GuardTower, specifically designed for prison facilities, extends access management and control capabilities to include additional personal communications services and devices. Its sophisticated design approach reduces implementation time and costs, while maintaining tight control of communications within the compound.
