System Architecture & Methodology

Understand how our nodes interconnect to form a resilient network.

Multi-Node Network Configuration

Infrastructure Nodes:
A core network of radio nodes is deployed at known positions to form a reliable reference system. These nodes—each equipped with a high-performance radio interface and a dedicated timer—serve as anchor points for determining distances and environmental characteristics.
Test and Extra Nodes:
Additional nodes, which may function as test nodes or operate exclusively in transmit or receive mode, can be seamlessly integrated. These nodes help verify device association with the environment and extend the system’s measurement capabilities.

Learn about our techniques for managing time offsets across devices.

Independent Timers with Managed Offsets:
Every radio node maintains its own timer, ensuring independence while allowing for precise management of time offsets. This synchronization is critical for achieving phase-coherent signal exchanges across the network.
Coherent Measurement Cycles:
Nodes participate in structured measurement cycles, where signals are transmitted and received in defined time slots. A carefully orchestrated sequence of steps – comprising an initial transmission and subsequent response – ensures that all signals remain phase-coherent, even in complex multipath environments.

Explore the step-by-step process from transmission to data transformation.

Step Sequence Operations:
Each measurement cycle is divided into step sequences. In a typical sequence, one node transmits an initial signal at a set carrier frequency. After a defined interval, another node transmits a response signal. This two-step process is repeated across various frequencies, enabling high-resolution sampling of the channel.
Frequency Domain and Time Domain Analysis:
We perform frequency sweeps or implement frequency hopping within a predetermined frequency domain. Advanced algorithms convert frequency-domain measurements into time-domain channel impulse responses, revealing both direct and indirect propagation paths.
Data Integration and Sensor Fusion:
Our architecture supports seamless integration of additional sensor data (such as from inertial sensors), enhancing both the accuracy and reliability of the derived position and motion profiles.

Discover built-in features that verify system integrity and prevent attacks.

Channel Characterization:
The system extracts comprehensive channel transfer functions that encapsulate the propagation behavior between nodes. These functions, along with precise time offset data, are used to perform integrity checks and validate the association of nodes within a defined radio environment.
Built-In Plausibility Testing:
By comparing the measured parameters from different nodes, our system can detect anomalies or inconsistencies – providing an additional safeguard against potential relay attacks or unauthorized device associations.
