Method for wireless data transmission
First Claim
1. 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.

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.

16. 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. - View Dependent Claims (17, 18)

19. 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.

20. 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.
