Technology

Our technology is built on a foundation of advanced radio signal processing techniques that enable:

• Accurate Distance Measurement: Utilizing coherent signal exchange, we determine precise distances between radio nodes by analyzing the propagation delay and signal phase across a defined frequency domain.
• Robust Positioning and Localization: Our systems extract position information from both direct and indirect signal paths, generating high-resolution location data even in complex, multipath environments.
• Environmental Sensing: By monitoring subtle variations in signal propagation, our technology creates a detailed “radio environment map” that captures the presence and dynamics of nearby objects and interference sources.
• Enhanced Security Against Relay Attacks: Our integrated methods evaluate interference characteristics and motion profiles to verify that all radio nodes and objects truly belong to the intended environment, providing an additional layer of defense for access systems.

Our method employs a multi-step measurement cycle in which radio nodes operate in different modes (transmitting, receiving, or both). Key aspects include:

• Coherent Signal Exchange: By ensuring that the transmitted signals are phase-coherent during each measurement cycle, we accurately extract both the direct transmission properties and the influence of indirect paths.
• Frequency Domain Analysis: We perform frequency sweeps and frequency hopping over a predetermined domain to gather a comprehensive dataset, enabling the resolution of complex propagation paths.
• Intelligent Evaluation: Advanced algorithms process the received signals to determine system transfer functions, time offsets, and environmental characteristics without the need for cumbersome additional hardware.
• Data Integration: Our solutions integrate seamlessly with additional sensor inputs (such as inertial sensors) to support sensor fusion, further enhancing the accuracy and reliability of position determination and environmental integrity checks.
