TOF (Time Of Flight)-Ranging


Based on Time Of Flight measurements the physical distance between two devices can be estimated. This process is called “ranging”. Although TOF measurements are subject to multipath effects (like any wireless technology) the precision which can be achieved in comparison with other methods e.g. Receive Signal Strength is significantly higher. We, nanotron Technologies, introduced the first commercially affordable chip solution with ranging capabilities to the market. Based on TOF estimation accurate zoning, secure access and virtual safety zone applications are possible (“collaborative localization”).

Principle of TOF collaboration

Individual radios based on an integrated transceiver chip with TOF capabilities are able to determine distances amongst them.

This way they achieve relative position-awareness.
