Abstract: A method comprises determining, by a radio, whether a current preferred radio station currently tuned to by a radio is experiencing a faded signal. Based on determining that the current preferred radio station is experiencing a faded signal, the method further includes automatically selecting, by the radio, a replacement preferred radio station. A radio with such capabilities is also disclosed.

Abstract: Various techniques are disclosed for assigning timeslots in a multihop wireless network. One such method includes, for each node for uplink timeslot assignments, assigning a higher hop count node to a timeslot that is to occur before all time slots assigned to lower hop count nodes. The method further includes, for each node for downlink timeslot assignments, assigning a lower hop count node to a timeslot that is to occur before all time slots assigned to higher hop count nodes.

Abstract: In an example, a method includes receiving, in a super frame, a first downlink on a first channel from a wireless master node at a wireless head node in a WBMS, where the wireless head node is a head node for a sub-cluster of one or more wireless devices. The method includes transmitting, in the super frame, a second downlink on a second channel from the wireless head node to each of the one or more wireless devices. The method includes receiving, in the super frame, an uplink from each of the one or more wireless devices at the wireless head node on the second channel. The method includes transmitting, in the super frame, an aggregated uplink from the wireless head node to the wireless master node on the first channel, where the aggregated uplink includes data from each of the one or more wireless devices.

Abstract: Aspects of this description provide for a computer program product comprising computer executable instructions. In at least some examples, the instructions are executable by a controller to cause the controller to broadcast, in a data frame, a scan request to a node, the scan request including a certificate of the controller and a public authentication key of the controller, receive, in the data frame, a scan response from the node, the scan response including a certificate of the node and a public authentication key of the node, and perform pairing between the controller and the node based on the public authentication key of the node and a private authentication key of the controller.

Abstract: A vehicular battery management system (BMS) comprises a battery controller, a set of battery cells, a primary network node coupled to the battery controller, and a secondary network node coupled to the set of battery cells. The primary and secondary network nodes are configured to wirelessly communicate with each other using frames that share a common frame format. The frame format includes one or more bits and a status of the one or more bits indicates whether the secondary network node is to communicate with the primary network node on behalf of another secondary network node.

Abstract: In an example, a wireless battery management system includes one or more sets of battery cells. The wireless battery management system includes a primary node configured to broadcast a downlink packet in a first superframe. The wireless battery management system also includes a first secondary node coupled to a first set of battery cells. The first secondary node is configured to receive the downlink packet and transmit a first uplink packet to the primary node during the first superframe. The wireless battery management system includes a second secondary node coupled to a second set of battery cells. The second secondary node is configured to receive the first uplink packet from the first secondary node in the first superframe. The second secondary node is also configured to transmit a second uplink packet to the primary node during a second superframe.

Abstract: In some examples, a vehicular battery management system (BMS) comprises a set of battery cells and a secondary network node coupled to the set of battery cells. The secondary network node is configured to wirelessly receive, in a first slot of a super frame, a unicast downlink packet from a primary network node, the unicast downlink packet addressed to the secondary network node. The secondary network node is also configured to wirelessly transmit, in a second slot of the super frame and responsive to the unicast downlink packet, an uplink packet to the primary network node.

Abstract: An integrated circuit for use in a wireless management system with a primary node and secondary nodes includes: a wireless transceiver; and a wireless management controller included with or coupled to the wireless transceiver. The wireless management controller is configured to: identify a first secondary node of the secondary nodes in communication with the primary node; identify a second secondary node of the secondary nodes not in communication with the primary node; and enable the first secondary node to operate as a proxy node that repeats downlink messages to or uplink messages from the second secondary node.
