Abstract:
A method of mapping a plurality of remote stations each having at least one varying attribute, including its position, affecting a characteristic value for the station, which characteristic value is computed according to a predetermined procedure from the at least one varying attribute, including the position, comprising:(a) assigning at least one transmission slot to cach of the remote stations; (b) determining, by the respective stations, of their characteristic values, said characteristic value being responsive to said determining of position; (c) initially transmitting, by the respective stations, of a signal responsive to their determined characteristic values in said at least one assigned slot, said transmitted signal being based on said characteristic value, said characteristic value being expressed with a first characteristic value resolution; and (d) subsequently transmitting, by the stations, of a signal related to their respective characteristic value in said at least one assigned transmission slot, said subsequent transmitted signal being based on said characteristic value having a finer characteristic value resolution relative to said first characteristic value resolution.
