Abstract
A method for localizing a device. The method is performed by a communication device. The method includes measuring a phase of a signal that the communication device has received from the device, the signal having a first frequency; measuring a phase of at least one further signal that the communication device has received from the device; the at least one further signal having a second frequency, determining a phase pattern of a measured phase versus frequency, pattern matching the phase pattern with each reference phase pattern of a plurality of pre-determined reference phase patterns. Each reference phase pattern is associated with a distance between the communication device and the further communication device. The method further includes determining the distance between the further communication device and the communication device based on the pattern matching.
