Abstract: A method and system for determining device presence in a mesh network and for directing messages to a destination within the network is presented. Node devices periodically issue device presences messages that are propagated through the network. Receiving devices store and analyze data from received device presence messages to determine presence and nodal distance to other nodes. Device presence message data can be used to route directed messages on the network and for network analysis.

Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

Abstract: A system, method and non-transitory computer readable media for facilitating network connectivity in a split architecture fronthaul network (102) comprising a plurality of cells (118-1 to 118-5, 120-1 to 120-5) and one or more BBU hubs (108A, 108B), each hub comprising at least a BBU (110-N, 112-M). An example cell allocation process (400B, 500A) is configured to assign cells to the hubs sequentially, i.e., a hub must be completely full (e.g., with respect to certain predetermined capacity such as port utilization) before adding cells to any other hubs. Once a hub is full, the allocated cells are further assigned to the individual BBUs of the hub also sequentially (500B). An optimal cell allocation map (418) is thereby obtained, which may be used in (re)configuring the connectivity between the cells (118-1 to 118-5, 120-1 to 120-5) and the hubs/BBUs (110-N, 112-M).

When an anomaly occurs in at least one element among the image generators and the display clients, the signal path determiner changes a signal path for transmission of the vehicle signal and the image signal from the first signal path to a second signal path.
