摘要： A method and device for selecting one or more transponders, in particular backscatter-based transponders, from a plurality of transponders by a base station, which method is based on a slotted ALOHA method, in which the base station defines numbered time slots and a random number generated in a given transponder determines a time slot when the transponder transmits its transponder-specific identification to the base station. The random number is generated in a given transponder with the aid of a random number generator, the relevant random number generator is switched into a counter operating mode after reception of a selection command transmitted by the base station, while a count state of the random number generator is decremented or incremented when the base station transmits the start of a time slot, the relevant transponder transmits a transponder-specific identification to the base station if the count state of its random number generator is equal to a predetermined value, and the relevant random number generator is then switched back into the operating mode for random number generation.

摘要： A method for data communication between a base station and at least one transponder by a high-frequency electromagnetic carrier signal is disclosed, onto which information packets are modulated, whereby each information packet has a header section, a middle section, and an end section and whereby the middle section has a data field for the transmission of data and/or address information and a protection field placed thereafter for the correction of errors in the transmission of the data and/or address information, whereby after the data field the base station inserts at least one control field, by which the protection field following the inserted control field can be changed in such a way that the duration of an information packet is set variably. The invention relates further to a base station for carrying out this method, to a data communication system containing a base station and at least one transponder in communicative wireless contact with the base station.

摘要： A method and apparatus for locating a transponder is provided. A carrier signal is transmitted by a base station and a transponder transmits a locating signal that is generated through phase modulation and backscattering of the carrier signal sent by the base station when the transponder is within a transmission range of the base station, whereby the transponder is located on the basis of the locating signal.

摘要： In certain embodiments, a method comprises receiving a data transmission comprising a header with a symbol and at least one symbol delimiter. The method may comprise monitoring the received data transmission to determine whether a time period between successive symbol delimiters of the header exceeds a maximum time. The method may comprise resetting a transponder to an initial state if the time period exceeds the maximum time. The maximum time may be determined based at least in part on the symbol after receiving successive symbol delimiters.
