Communication method in RFID or remote sensor systems
First Claim
1. A Method for communicating between a control unit and a plurality of remote units located in a response area of the control unit, the method comprising the steps of:
- transmitting a command from the control unit to the remote units;
transmitting a data sequence to the control unit upon receipt of the command sent by the control unit; and
transmitting a control signal from the control unit to the remote units substantially simultaneously with the transmission of the data sequence from the remote units on a basis of a communication state, the communication state being an absence of a transmission of the data sequence by at least one of the remote units or an at least partially simultaneous transmission of the data sequence by more than one of the remote units.

Abstract
A method for communicating between a control unit and a plurality of remote units located in the response area of the control unit is provided. The remote units are prompted to transmit a data sequence to the control unit upon receipt of a command sent by the control unit. The control unit transmits a control signal to the remote units substantially simultaneously with the transmission of the data sequence as a function of a communication state, such as the absence of a transmission of the data sequence by at least one remote unit or an at least partially simultaneous transmission of the data sequence by more than one remote unit. In this way, communication methods can be shortened, in particular in terms of time, without adversely affecting communication reliability.
