PROBLEM TO BE SOLVED: To solve the problem that, when interpreting a radio-electrical command for equipment, it may be necessary occasionally to interpret the radio-electrical command as a function of a radio emission zone, because of characteristics of the equipment.SOLUTION: A radio-electrical command is received by two or more antennas in the vicinity of a device for reception of radio-electrical commands and electromagnetic characteristics of electromagnetic fields generated in the two or more antennas are compared. The electromagnetic characteristics are compared to determine whether a transmission point of the radio-electrical command is located in a so-called near-field zone or in a so-called far-field zone and then the command is executed as a function of the received command and as a function of the emission zone of the command. Thus, the same command is permitted to have two meanings for the equipment. |
