Abstract: In some examples, a wireless device includes a communication interface to communicate with a wireless network, and at least one processor configured to, receive, from an access point (AP), information including a network address policy of the wireless network. The at least one processor is configured to further, in response to the information including the network address policy, use an address of the wireless device according to the network address policy.

Abstract: In some examples, a first wireless device transmits, within a first band designated for vehicle-related communications, service information for a service, the service information comprising information of a channel in a second band for communication of data of the service, the second band being outside of the first band.

Abstract: A method for balancing sensors within a sensor system, the method including receiving, at a gateway, data from a plurality of sensors, each of the plurality of sensors being connected to one of a plurality of sensor modules or the gateway; determining, at the gateway, that a signal strength from a first sensor falls below a threshold, the first sensor being one of the plurality of sensors; and based on the determining, allocating the first sensor to connect to a different one of the plurality of sensor modules, or to the gateway if connected to one of the plurality of sensor modules.

Abstract: In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.

Abstract: A device includes a link layer configured to use a first link layer address and a second link layer address, maintain the first link layer address unchanged for a duration of an association of the device with a wireless network, and change the second link layer address from a first value to a second value during the duration.

Abstract: In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the first parameter set to control a setting of the one or more adjustable elements of the vehicle.

Abstract: A method at a sensor module within a sensor system for communicating with a gateway, the method including storing a timing profile for communications with the gateway; waking a radio core of the sensor module at a threshold time prior to a beacon signal being expected from the gateway; sampling a channel for the beacon signal at the radio core; if the beacon signal is detected: waking a processor on the sensor module; exchanging communication with the gateway; and powering down the processor and radio core upon completion of the exchanging communication.

Abstract: A method at a computing device within an Intelligent Transportation System, the method including detecting a traffic event at the computing device; determining no fixed roadside unit is available from the computing device; establishing an Internet Protocol connection from the computing device to a network node; and sending a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event.

Abstract: In some examples, a system receives information based on wireless sensing performed using wireless signals of a wireless interface of a wireless node, the wireless interface of the wireless node to communicate data over a wireless connection established with another wireless device. The system performs authentication in response to the received information.

Abstract: In some examples, an access point determines, based on at least one criterion that includes a non-time based criterion, whether to activate group-addressed transmission of information relating to an access network. In response to determining, based on the at least one criterion, to activate group-addressed transmission of information relating to the access network, the access point transmits information relating to the access network in a message targeted to a group address.

Abstract: A device includes a link layer configured to use a first link layer address and a second link layer address, maintain the first link layer address unchanged for a duration of an association of the device with a wireless network, and change the second link layer address from a first value to a second value during the duration.

Abstract: An access point advertises a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame. Each mobile station associated with the access point is to prioritize transmission of management frames according to the MFQ policy advertised by the access point, unless a policy configuration request for the mobile station to prioritize transmission of management frames according to a different MFQ policy has been accepted.

Abstract: Network information may be discoverable without requiring a connection to that network. For example, Access Network Query Protocol (“ANQP”) may allow a device to discover information about a network prior to the device associating with that network. In other words, ANQP allows a network terminal to request additional network information prior to establishing network capability. The additional network information that may be discoverable includes network latency, cellular capabilities, hotspot capabilities, mobility capabilities, neighbor reports, station identification, and multiple hotspot session identification.

Abstract: In some examples, a first wireless device sends, to a second wireless device, a control indication that controls transmission of group-addressed data between the first wireless device and the second wireless device over a wireless local area network (WLAN).

Abstract: Methods and devices for encoding a point cloud. A current node associated with a sub-volume is split into further sub-volumes, each further sub-volume corresponding to a child node of the current node, and, at the encoder, an occupancy pattern is determined for the current node based on occupancy status of the child nodes. A probability distribution is selected from among a plurality of probability distributions based on occupancy data for a plurality of nodes neighbouring the current node. The encoder entropy encodes the occupancy pattern based on the selected probability distribution to produce encoded data for the bitstream and updates the selected probability distribution. The decoder makes the same selection based on occupancy data for neighbouring nodes and entropy decodes the bitstream to reconstruct the occupancy pattern.

Abstract: Systems, methods, and software can be used to improve security of an authentication process in a cargo shipping system. In some aspect, an authentication request message is received at a sensor from a cargo tracking device. The authentication request message includes a key that the sensor will use to decrypt its encrypted public key/private key pair. In response to the authentication request message, the sensor sends an authentication response message to the cargo tracking device that is encrypted using a derived symmetric key. The cargo tracking device sends an authentication confirmation message to the sensor in response to the authentication response message.
