How It Works

Precision Cellular Tracking

Process Workflow

1
Signal Reception: Multiple fixed antennas receive cellular and RF emissions within the monitored spectrum.
2
Selective Filtering: Adjustable bandwidth filters isolate the target cellular signal, reducing interference from surrounding RF activity.
3
High-Precision Processing: SDR-based algorithms analyze phase and amplitude relationships across antenna inputs.
4
Direction Estimation: The system calculates the Direction of Arrival with high angular accuracy using coherent or non-coherent methods.
5
System Integration: Bearing data is provided via API and combined with IMSI catcher outputs to enable accurate triangulation and localization of unauthorized mobile devices.

Preparation & Setup

Install DF-210 as part of a permanent, fixed infrastructure. Deploy and align the antenna array according to site layout. Connect the system to facility power and network infrastructure. Integrate DF-210 with IMSI catcher or cellular monitoring systems. Configure signal-selection parameters and begin continuous operation.

Operational Use

DF-210 is purpose-built for secure environments where mobile phones are prohibited, including: Correctional facilities and prisons, Detention centers, High-security government buildings, Restricted institutional environments.

Maintenance & Lifecycle

Solid-state SDR architecture with no moving parts. Designed for continuous, long-term operation. Minimal maintenance requirements. Software-driven updates and algorithm improvements. Suitable for fixed, infrastructure-level deployments.
