Abstract: The validity of sensor data of an Ethernet onboard network in a motor vehicle is checked by: determining a delay time of a first signal on a first connecting path between a first control unit of the Ethernet onboard network and a second control unit of the Ethernet onboard network; determining a maximum speed of the first connecting path on the basis of the delay time; and determining a type of a transmission medium of the first connecting path on the basis of the maximum speed. The following steps are also carried out: identifying at least a first control unit of the Ethernet onboard network, synchronizing at least a first control unit of the Ethernet onboard network, ascertaining the synchronization interval, ascertaining a drift of a timer of the first control unit, ascertaining a timestamp of the first control unit, reading a timestamp of the first control unit.

Abstract: In busy 5G and 6G networks, precise timing and synchronization are key to maintaining throughput with low fault rates. Disclosed are systems and methods for adjusting each user device's clock for proper reception, including downlink propagation delays, uplink propagation delays, round-trip propagation delays, and Doppler shifts, individually for each user device, and including any uplink/downlink asymmetries. The clock adjustment and timing advance of each user device is based on a predetermined transmission schedule for timing signals, broadcast by the base station. The Doppler shift is measured by the base station, according to uplink timing signals, and communicated to the user device in a single final timing signal. The single final timing signal is either frequency-shifted by the measured Doppler shift, or delayed proportional to the Doppler shift, either of which indicates, to the user device, how to apply the correct timing to future uplink messages.

Abstract: An optical communication device connected to an optical path in an optical communication network includes a controller. The controller generates an additional information signal having a carrier frequency different from a carrier frequency of a main optical signal. The controller generates an output optical signal by superimposing the additional information signal on the main optical signal, and outputs the output optical signal to the optical path. The additional information signal includes a time stamp reflecting a timing at which the additional information signal is generated.

Abstract: An aggregate cell of a cellular network includes a plurality of dispersed modular cells. The modular cells each include a cellular radio and collectively perform the function of a cellular base station. A distributed clock is established by transmitting timing beacons from one or more of the modular cells. Each modular cell receives the timing beacons. Each modular cell that transmits a timing beacon provides a transmission timestamp to a cell controller. Each modular cell that receives a timing beacon provides a reception timestamp to the cell controller. The cell controller schedules signal transmissions from the modular cells based on the transmission and reception timestamps.

Abstract: In certain embodiments, a communication network has a specialized ingress node that converts one or more incoming flows into a single, packetized, time-division multiplexed (TDM) flow; a switch fabric that routes the TDM flow via a fixed path through the switch fabric in a contention-free manner; and a specialized egress node that converts the TDM flow received from the switch fabric into one or more outgoing flows corresponding to the one or more incoming flows. The technology turns legacy, best-effort packet-switching into deterministic circuit-switching for a programmable selection of flows with minimal impact on network dynamics and at relatively low cost.

Abstract: Prior art includes complex clock synchronization in 5G and 6G based on precision time measurements and multiple message exchanges. Disclosed is a simpler synchronization procedure suitable for reduced-capability receivers as well as high-performance users. The base station can transmit a brief signal on a specific subcarrier, surrounded fore and aft by silent periods, and the receiver can measure the signals in the silent periods to detect intrusion of the signal into one or the other silent periods, thereby indicating a timing offset. Alternatively, the base station can transmit a brief signal spanning an interface between subsequent symbol-times, and the receiver can measure the energy received in the two symbol-times, thereby detecting an offset. In either case, and other versions disclosed, the receiver can calculate the size and direction of the clock offset by amplitude measurements, and apply a correction without further communications between the user device and the base station.
