摘要： A method for transmission of data requires a transmitting node sending a request message identifying at least one time slot that is available for the transmitting node to transmit a data transmission to a plurality of receiving nodes, a first receiving node transmitting a first time slot grant message in response to the request message, a second receiving node transmitting a second time slot grant message in response to the request message, the transmitting node receiving the first and second time slot grant messages, the transmitting node evaluating the first and second time slot grant messages to determine at least one available time slot for transmitting, the transmitting node transmitting at least one confirmation message to the first and second receiving nodes, and the transmitting node transmitting the data transmission in the at least one available time slot identified in the at least one confirmation message.

摘要： A system and method are disclosed for position location in an enclosed environment. In at least one embodiment, the system includes an enclosed environment with several distributed RFID transponders and an RFID processing unit for wireless communication with the RFID transponders via an electromagnetic coupling field. In each of the RFID transponders, an identifier assigned to the respective position of the RFID transponder in relation to the enclosed environment is stored. In at least one embodiment, the RFID transponders and the RFID processing unit are configured in such a way that if the RFID processing unit is positioned such that at least one RFID transponder is within a transmission range of the electromagnetic coupling field, the identifier of the RFID transponder is automatically transmitted to the RFID processing unit.

摘要： In a method for calibrating a propagation-time-based localization system in a computer-assisted manner, the position of a mobile object in a predetermined environment can be determined by detecting propagation-time-based variables of multiple base stations, wherein the propagation-time-based variable of a base station represents the propagation time of a signal between an object radio unit and the base station. The object is moved and the variables of the base stations are detected in the process at multiple measuring times. The minimum value of the variables of a base station is associated with a predefined minimum distance between the object and base station and the maximum value with a predefined maximum distance. A predefined dependence of the distances between the object and base station is scaled to the association of the minimum and maximum value. The scaled dependence is then used when determining the position of the mobile object.

摘要： In a multi-hop network, packets are classified into header and user data for coded distribution. The header information, especially the multi-hop information, is separated in a coded manner from the user data, such that each network node need only decode the header in order to forward the packet. The header and the user data are guided, independently from each other, to the hardware of the respective device for separate coding, as if they were complete packets. A hardware accelerated coding of header and user data is possible using different keys. The header also contains integrity protection.
