Patent number: 9712517Abstract: In an ad hoc mesh network, roles are assignment to the different network nodes, for example mesh point or mesh portal. The invention envisages that a network node identifies the certification and thus the permitted roles of another network node before it sends a message to said other network node. This ensures that the roles maintain their integrity and the security in the network is enhanced.Type: GrantFiled: June 30, 2015Date of Patent: July 18, 2017Assignee: Unify GmbH & Co.

Patent number: 9191877Abstract: Method for wire-free transmission of data packets between network nodes in a control network, wherein the data packets each have a preamble for synchronization consisting of a predetermined number of preamble symbols, and wherein during a first operating mode, each preamble-subsymbol of a preamble symbol in the preamble is coded by the phase angle of a transmitted single signal pulse, during a second operating mode to increase the signal recognition performance, for the preamble which is transmitted in the data packet, a signal pulse sequence for coding the preamble-subsymbol is transmitted instead of a single signal pulse, where the single signal pulse within the signal pulse sequence is transmitted repeatedly.Type: GrantFiled: March 1, 2011Date of Patent: November 17, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Johannes Hund, Andreas Heinrich, Stephan Huckenholz, Christian Schwingenschlögl

Patent number: 9155011Abstract: A method for transmitting data in a wireless radio network having a multiplicity of base stations for wirelessly sending and receiving data, wherein the base stations are wirelessly networked such that each base station can communicate wirelessly with one or more adjacent base stations. Broadcast messages are transmitted between a mobile station for wirelessly sending and/or receiving data and the base stations and broadcast messages are also forwarded between the base stations. These broadcast messages do not have an associated explicit connection between two units in the radio network. Moreover, the mobile station which receives a broadcast message can process this message regardless of the base station from which it originates. This avoids so-called “hand offs,” which are used in the prior art to associate a mobile station with a new base station when the mobile station moves out of range of the earlier base station.Type: GrantFiled: June 26, 2008Date of Patent: October 6, 2015Assignee: Siemens AktiengesellschaftInventors: Claus Gruber, Matthias Kutschenreuter, Christian Schwingenschlögl, Andreas Ziller

Patent number: 8705589Abstract: An ultra-broadband signal having a plurality of pulses is transmitted from one or more transmitting nodes to one or more receiving nodes. In the ultra-broadband signal, data are transmitted by pulses having a first pulse rate in a first data transmission and by pulses having a second pulse rate in at least one second data transmission, with each second pulse rate higher than the first pulse rate. The pulses having the second pulse rate are transmitted in intervals, during which no pulses having the first pulse rate are transmitted. This has the advantage that by utilizing time gaps between pulses of the first data transmission, the data of a second data transmission can be transmitted at a higher pulse rate. The transmitting and receiving nodes need not be coordinated explicitly or coordinated from the outside.Type: GrantFiled: September 24, 2009Date of Patent: April 22, 2014Assignee: Siemens AktiengesellschaftInventors: Andreas Heinrich, Johannes Hund, Christian Schwingenschlögl

Patent number: 8494556Abstract: 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.Type: GrantFiled: July 16, 2010Date of Patent: July 23, 2013Assignee: Siemens AktiengesellschaftInventors: Maksym Marchenko, Alejandro Ramirez, Christian Schwingenschlögl

Patent number: 8428615Abstract: A method and a device for determining a position of a communication apparatus is provided. To determine a position of a first apparatus a first signal is transmitted from a second apparatus to the first apparatus. A second signal is then transmitted from the first apparatus to the second apparatus as a response to the first signal, the first signal and the second signal being transmitted by way of at least two different mediums. Signal strength of the second signal received by the second apparatus and a transfer time from a first time of transmission of the first signal to a second time of receipt of the second signal are measured. The position of the first apparatus is finally calculated as a function of the measured signal strength of the received second signal and the measured transfer time.Type: GrantFiled: August 18, 2009Date of Patent: April 23, 2013Assignee: Siemens AktiengesellschaftInventors: Alejandro Ramirez, Christian Schwingenschlögl

Patent number: 7881212Abstract: A method determines a route in distance value for use in routing protocols. An optimum route is determined for time-critical transmissions such as videotelephony or VoIP. For this purpose, the route distance value is calculated as the product of the link metrics for the links of a route, said link metrics being the product of data packet arrival rates. This value is the optimum value for the route which requires the lowest number of repeated packet transmissions (retransmissions). Optionally, an additional factor can be inserted in the link metrics, which factor ensures that the length of a route is also taken into consideration.Type: GrantFiled: January 26, 2007Date of Patent: February 1, 2011Assignee: Siemens AktiengesellschaftInventors: Matthias Kutschenreuter, Christian Schwingenschlögl

Publication number: 20100260153Abstract: In a method for data transmission in a mesh mode of a wireless communication network, which enables a decentralized transmission of data packets within data streams via communication links from one node to another node, data streams are classified in several service classes specifying quality requirements for data streams. Bandwidth reservations are performed between nodes of a communication link, each bandwidth reservation being dependent on the service class of the data stream to be transmitted via the communication link and comprising the exchange of control messages for reserving time slots for transmitting the data stream of the service class in subsequent data time frames via the communication link. The transmission of data streams is scheduled dependent on the service classes. The method is particularly used in the mesh mode of the standard IEEE 802.16 and enables a seamless coexistence of the point-to-multipoint mode and the mesh mode of the standard.Type: ApplicationFiled: December 5, 2008Publication date: October 14, 2010Inventors: Matthias Hollick, Parag Sudhir Mogre, Christian Schwingenschlögl
