Abstract

A device is arranged for distance measurement according to a ranging protocol using a measurement message from a second device. Based on a first arrival time of the measurement message a first distance () between the first device () and the second device () is determined. A third device () acts as a cooperating device that is located at a trusted distance (). The cooperating device determines a third arrival time of the same measurement message, and transfers support data to the first device, the support data being based on the third arrival time. The first device obtains a third distance () between the third device and the second device using the support data. Then a verification test is performed on the first distance (), the trusted distance () and the third distance (). The first distance is reliable when said distances correspond to a viable spatial constellation () of the devices.
