Abstract
A coded system for radio-frequency communication (RFC); the system comprising at least one base station (20) and a plurality of mobile devices (10); the base station and mobile devices are individually provided with running time information synchronized inter se; the mobile device is adapted for transmitting an identifying signal to the base station device; the base station is adapted for receiving the signal; wherein the signal further comprises a preamble including a miming-time-dependent code generated according to a predetermined algorithm (220); the base station is adapted for comparing the code with a reference code generated by the base station according to the algorithm (260), authorizing the RFC in response to coincidence of the running-time-dependent codes generated by the base station and the mobile (270).
