Method for interpretation of a radio-electrical command
First Claim
1. A method for interpreting a radio-electrical command, which comprises the following steps:
- determining electromagnetic characteristics of the field caused by the radio-electrical command in the vicinity of a device for receiving radio-electrical commands, by comparing these characteristics with one another, determining whether the transmission point of the radio-electrical command lies in a so-called near-field zone or in a so-called far-field zone, executing a control as a function of the received command and as a function of the transmission zone of the command.

Abstract
The invention relates to a method for interpretation of a radio-electrical command for equipment in which the command is interpreted as a function of the emission zone. This is achieved whereby the electromagnetic characteristics of the field generated by the radio-electrical command in the vicinity of a device for reception of radio-electrical commands are determined. The characteristics are compared to determine if the point of the radio-electrical command is located in a near-field or in a far-field zone. A command is then carried out as a function of the command received and as a function of the emission zone of the command. This permits the same command to have two meanings for the equipment.
