Abstract
A first device () for distance measurement via wireless communication () uses a ranging protocol for determining a distance () to a second device () via a round trip time measurement, wherein first time data represents the round trip time and second time data represents a response time between receiving a request and sending a corresponding acknowledge. The second device receives the round trip time and determines the distance. The first device determines third time data by subtracting from the first time data a calculated travelling time of the messages between the first device and the second device based on the determined distance, and determines identifier data indicative of hardware and/or software present in the second device. The device then obtains, from a database based on the identifier data, a reference interval value, and verifies whether the determined distance is reliable by comparing the third time data to the reference interval value.
