摘要： A method for communicating between a first device and a second device is shown. The devices are structured and configured for communicating via a communication channel by exchanging messages. The method comprises: a) the first device transmits N≧2, challenge messages to the second device; b) for each of said N challenge messages, the second device, in reaction to receiving the respective challenge message, carries out a processing on the respective received challenge message and thereby generates a respective response message, and transmits the respective response message to the first device; c) the first device receives the transmitted N response messages and determines, for at least one of the received response messages, a time elapsed between the transmitting of the respective challenge message and the reception of the respective response message; d) the first device computes, in dependence of said determined time or times, of a value indicative of a travelling speed of the challenge and the response messages and of a value indicative of a processing time assumed to be required by the second device for carrying out said processing, a value relating to a distance between the first and the second device.

摘要： The method for communicating between a first device and a second device includes the steps of: the first and second device communicating by exchanging messages that are based on signals that are transmitted through a plurality of communication channels; the first device sending a challenge message to the second device over one communication channel; the second device sending, upon reception of the challenge message, a response message to the first device through at least two communication channels that have essentially identical signal propagation velocities; the first device measuring the time elapsed between the sending of the challenge message to the reception of the response message; and the first device computing its distance to the second device based on this time, knowledge about travelling speed of the challenge and the response message and the processing delay that the second device adds to generate and send the response message.
