A wireless communication method and a device are provided. The wireless communication system includes a second control device, at least one first control device, and at least one terminal. The second control device transmits a first synchronization signal, where the first synchronization signal provides synchronization information of at least one communication sub-system in a wireless communication system.

A work site equipment grouping system includes a plurality of work machines including a first work machine and a second work machine. Each work machine is configured to wirelessly communicate with other work machines. The system further includes a local area network including a plurality of communicatively connected nodes, the nodes including the first work machine and the second work machine. The system further includes a third work machine configured to detect one of the first work machine or the second work machine within a signal range of the third work machine and, upon detecting one of the first work machine or the second work machine, automatically join the local area network.

A system for updating vehicle time information includes a communication device configured to wirelessly communicate with a wireless network using a network communication protocol. The system also includes a processing unit configured to assess communications between the vehicle to determine whether a condition related to a potential local time offset error exists, and based on determining that the condition exists, transmit a message supported by the communication protocol to the wireless network. The message is configured to prompt the wireless network to return a response message including a local time offset. The process is also configured to update a vehicle local time record based on the local time offset.

Provided are methods for enhanced proactive transceiver and carrier automated arbitration for a vehicle. Some methods described include receiving route information representing a route to be traveled by the vehicle, and determining, based on a prediction model and the route information, a first connectivity score of a first transceiver and a second connectivity score of a second transceiver. Some methods described include comparing the first connectivity score against the second connectivity score, and selecting, based on the first connectivity score being greater than the second connectivity score, the first transceiver. Some methods described include determining, using location information, a current second connectivity score of the second transceiver, and connecting, based on comparing the current second connectivity score against the first connectivity score, the vehicle to the first transceiver or the second transceiver for performing wireless communications. Systems and computer program products are also provided.

A method of causing car sharing platform user to perform vehicle actions includes training a model by analyzing historical data; analyzing a first data set to determine vehicle requirements comprising respective actions that include respective action values; displaying the actions; receiving user acceptance of the actions; analyzing a second data set to identify changes to the requirements indicating completed actions; and releasing the respective generated action value for the completed actions. A non-transitory computer readable medium containing program instructions that when executed, cause a computer system to: train a model by analyzing historical data; analyze a first data set to determine vehicle requirements comprising respective actions that include respective action values; display the actions; receive user acceptance of the actions; analyze a second data set to identify changes to the requirements indicating completed actions; and release the respective generated action value for the completed actions.

A portable communication system for use in hostile and unknown environments. The system has a base station for control by an operator. The base station dispatches one or more unmanned drones into the hostile environment, where a forward agent, such a robot or investigative person can approach a suspected threat. Each drone has a payload of repeaters to be delivered as necessary to maintain line of sight communication from the forward agent back to the base station. Once delivered, the repeaters are mobile and can autonomously reposition to maintain or optimize line of sight communication. Communications from the forward agent back to the base station are then interpreted and analyzed for further action.

Systems and methods for restricting the use of vehicle operator's electronic device are provided. In a method a telematics server determines that a vehicle's engine is running, and that the operator registered with the vehicle is in the driver's seat. In response, the telematics server sends a message to the vehicle operator's terminal for changing the configuration thereof. A system including a telematics device, telematics server, and operator terminal may carry out the method. The system and method can be used to restrict the use of electronic devices by drivers sitting in a vehicle with the engine running in accordance with laws in certain jurisdictions.

A multi-layer path-planning system and method calculates trajectories for autonomous vehicles using a global planner, a fast local planner, and an optimizing local planner. The calculated trajectories are used to guide the autonomous vehicle along a bounded path between a starting point and a destination.
