Abstract
A method for wireless data transmission between a base station and one or more, in particular passive, transponders is provided, in which electromagnetic carrier waves are emitted by the base station. Data comprising successive characters are transmitted from a respective transponder to the base station by modulation and backscattering of the electromagnetic carrier waves, and a respective one of the characters is coded and transmitted by a respective transponder within a predefined time interval. Within at least one of the predefined time intervals, a safeguard character formed from the data to be transmitted is transmitted in addition to the character to be transmitted.
Claims20
A method for wireless data transmission between a base station and one or more transponders, the method comprising the steps of:
- emitting electromagnetic carrier waves by the base station;
- transmitting data comprising successive characters from a respective transponder by modulation and backscattering of the electromagnetic carrier waves;
- and
- coding and transmitting a respective one of the characters by the respective transponder within a predefined time interval for coding and transmitting a single character;
- wherein, within at least one of the predefined time intervals, a safeguard character formed from the data to be transmitted is transmitted in addition to the character to be transmitted.
A method for wireless transmission between a base and at least one transponder, the method comprising the steps of:
- determining a coding type;
- forming a safeguard character from payload data;
- and
- selecting a predefined time interval corresponding to transmission of a single character for transmitting the safeguard data and the payload data based upon the determination of the coding type.
A wireless transponder, comprising:
- an execution unit;
- a memory functionally coupled to the execution unit, containing instructions causing the processor to determine a coding type, form a safeguard character from payload data, and select a predefined time interval corresponding to transmission of a single character for transmitting the safeguard data and the payload data;
- and
- a multiplexer functionally coupled to the execution unit, which combines payload data and safeguard data based upon intervals determined by the execution unit.
A method for wireless data transmission between a base station and one or more transponders, the method comprising:
- emitting electromagnetic carrier waves by the base station;
- transmitting data including successive characters from a respective transponder by modulation and backscattering of the electromagnetic carrier waves;
- coding and transmitting a respective one of the characters by the respective transponder within a predefined time interval for coding and transmitting a single character;
- forming a safeguard character from the data including the successive characters;
- and
- transmitting the safeguard character within a same predefined time interval as the transmitting of the respective one of the characters.
