CellDefender™ Cellular Access Management System

L3Harris' CellDefender™ cellular access management system offers an immediate solution to the issue of unauthorized use of cell phones within a secured area. Using our breadth of cellular expertise, L3Harris provides contraband interdiction systems, enabling comprehensive control of contraband phones in prison facilities.

Unlike cell phone jammers, CellDefender is a complete managed access solution that establishes a real cellular network to mitigate unauthorized communications on all bands and across all protocols, including 2G, 3G, and 4G technologies.

CellDefender is designed to allow administrators to manage access to public cellular networks with the option to customize access by allowing emergency calls and up to 40 authorized users to connect to the network unimpeded. It is specifically optimized for each facility based on local commercial cellular coverage, layout of the premises, and best practices for cellular signal control. By customizing the system to cover just the commercial cellular bands and technologies that are in use at the specific facility, the solution minimizes hardware and installation costs, while allowing the facility to limit access to the commercial carrier networks. Additionally, tailoring each facility coverage area ensures the functionality is not extended beyond the facility boundaries.

CellDefender's cellular managed access mitigates inmate phone calls on contraband prison phones.

The CellDefender perimeter-based distributed antenna system ensures coverage facility wide and prevents inmates from making a successful connection in a non-covered zone and dragging the call inside the facility. The system also automatically and continuously monitors the local cellular network and alerts administrators to any changes in the environment so adjustments can be made to ensure continued coverage. Coupled with L3Harris’ commitment to invest in future bands and frequencies, like 5G, CellDefender is prepared for the future in the dynamic cellular environment.
