The method (500) includes monitoring, at management communication device (1050), WiFi broadcast signals from wireless communication devices (1055). The method (500) also includes managing the strength and reception sensitivity of each of the WiFi broadcast signals on each of the wireless communication devices (1055). Each of the wireless communication devices (1055) is assigned to a set of wireless communication devices. The method (500) also includes prioritizing, at management communication device (1050), each of the wireless communication device (1055).

In one embodiment, a method comprises determining a movable network device is moving along a repeatable sequence of access point devices in a deterministic network; and establishing a deterministic track along the repeatable sequence of access point devices, the deterministic track comprising insertion slots allocated for insertion of a data packet, by the movable network device, into the deterministic track via any one of the respective access point devices.

This disclosure relates to a method of safely and automatically navigating in the presence of emergency vehicles. A first vehicle may receive, via communication hardware, a message indicating presence of the emergency vehicle. Such a message may originate from the emergency vehicle itself and/or from infrastructure such as a smart traffic light that can sense the presence of the emergency vehicle. The first vehicle may then determine the relative location of the emergency vehicle and automatically respond appropriately by determining a safe trajectory and navigating according to that trajectory until the emergency vehicle is out of range. In some examples, the first vehicle may detect the presence of an emergency vehicle using on-board sensors such as distance measuring sensors, depth sensors, and cameras, in addition to receiving a message via communication hardware.

This patent application discloses methods and systems for alerting computerized motor-vehicles about predicted accidents. In an example method, a motor vehicle alerts another motor vehicle about a predicted accident, even though that accident is between the alerting car and a third motor vehicle—for example, the alert is transmitted by non-visual electromagnetic (EM) radiation. When an adjacent motor vehicle receives such accident alert and determines it might itself be hit, it will react so as to minimize its chances of being hit or at least to minimize the damage if it is being hit. Optionally, one or more of the motor vehicles has an onboard device for measuring a blood-alcohol level of a human driver thereof. The measured blood-alcohol level may be used to compute a probability of an occurrence of an accident and/or may be included in one or more of the transmitted accident alerts.

Mobile base station information is exchanged with an other base station. One or more parameters are exchanged with the other base station based on the base station information. A mobile base station is configured based at least in part on the negotiated one or more parameters. The configured mobile base station is used to provide cellular coverage to one or more user devices.

Sensors within sensor node networks may communicate bio-event or other types of measurement results/decisions between each other using signal transmission variations. Each sensor node within a network and between networks may transmit and receive signals. A sensor node may scale a signal transmission power in a manner that is proportional to a confidence level of a decision or measurement about an event being detected. Each sensor node will receive transmissions from neighboring nodes, and can refine an estimate about an occurrence of the event at its location based on received signal strengths, for example.

A wireless communication system for a moving vehicle, such as trains, is disclosed. The system includes at least one router in the moving vehicle for receiving and transmitting wireless voice communication and data communication to and from a stationary communication server outside the moving vehicle through an exterior mobile network. Further, the system includes at least one femtocell provided within the moving vehicle, and being connected to the router for wireless transferring of wireless voice communication and data communication between mobile terminals within the moving vehicle and the router. The at least one femtocell is controlled by a femtocell controller directly or indirectly connected to the communication server outside the moving vehicle.

Systems and methods are provided for routing path optimization in a network of moving things. A mobile access point (MAP) of a vehicle communication network may include one or more processors configured to determine a path score for each of a communication paths to a destination for a communication, based on at least one vehicle-dependent feature associated with at least one reachable mobile node, with the at least one vehicle-dependent feature including, for each reachable mobile node, one or more of expected travel route of the reachable mobile node, an expected down time of the reachable mobile node, an expected time of high utilization of the reachable mobile node, and a degree to which the reachable mobile node is presently in-range. The one or more processors may select a route for the communication based on the determined path scores for the communication paths.

Embodiments include devices, systems and/or methods of communicating with a vehicle (102) along a transportation route (104). For example, a system may include a plurality of access points (APs) (120) along the transportation route, an AP of the plurality of APs including a directional antenna (123) to communicate with the vehicle moving along the transportation route via a directional link (127); and at least one AP manager (132) to control handover of the vehicle between the plurality of APs. Communicating with the vehicle may include switching a directional antenna of an AP of the plurality of APs between a plurality of beam settings to steer the directional antenna towards a respective plurality of coverage areas of the transportation route. For example, AP (128) may switch directional antenna (123) between the plurality of beam settings to steer directional antenna (123) towards the respective plurality of coverage areas of transportation route (104). For example, controller (136) may handover vehicle (102) between the plurality of APs (120) according to the order of the plurality of segments (110). Alternatively, controller (136) may handover vehicle (102) from AP (122) to AP (124) based on the quality of communication between AP (122) and vehicle (102). Moreover, controller (136) may handover vehicle (102) from AP (126) to AP (128), when vehicle (102) moves from segment 116 to segment (118).

Recursive constellations of Ultra-Wide Band (“UWB”) transceivers are optimized based on a desired functionality or objective. By structuring transceivers of an UWB network into a plurality of subsets or constellations of UWB nodes each constellation can be optimized for a particular purpose while maintaining connectivity and cohesiveness within the overarching network. Implementations of specific functionality can be applied to Intra-Vehicle, Inter-Vehicle and Vehicle-to-Infrastructure constellations resulting in localized optimizations while maintaining a cohesive and coherent UWB network.
