Abstract: An example system may include a plurality of wireless radio chains of a radio operating at a channel in a wireless network and a processor to receive a ranging measurement request for a client device not associated with the wireless network, split a subset of wireless radio chains from the plurality of the wireless radio chains, and use the subset of wireless radio chains to service the ranging measurement request.

Abstract: A method including selecting multiple dedicated radios on a transmission channel and programming multiple association identifiers on each dedicated radio is provided. Each of the association identifiers is configured to detect a resource unit assigned to one of multiple stations. The method includes providing multiple packets collected from the dedicated radios to a server and merging the packets from the dedicated radios to identify at least one station. Merging the packets includes identifying a preamble in the packets from the dedicated radios, matching the preamble from different dedicated radios, combining a data portion of the packets from different dedicated radios whose preamble match, selecting a time-stamp from one of the dedicated radios, and associating the time-stamp with the data portion. A system and a non-transitory, computer readable medium storing instructions to perform the above method are also provided.

Abstract: Systems and methods are provided for optimizing the channel switching process in an access point. Periodic background scanning of a current channel on which a radio is operating to determine channel utilization can be used to generate a ranked channel list from which to select an alternative channel to which the radio can migrate, for example, in the event of a radar signal(s) being detected on its current channel. To maintain connectivity for clients, the clients may be temporarily transitioned to a non-DFS channel while an isolated/dedicated radio chain is used to perform the requisite Channel Availability Check (CAC) assessment on a DFS channel if the radio, based on the ranked channel list, selects a DFS channel as the alternative channel.

Abstract: Dynamic configuration of multiple radios of an access point is described. An example of an access point includes a processor; a memory; hardware filters; and a first set of radio chains and antennas, the access point including a first radio mode for operation as a single radio on a first channel to service a first BSS and a second radio mode for operation as a first radio on the first channel and a second radio on a second channel to perform an additional service, wherein the access point is to provide dynamic configuration of the radios including, upon determining that operation of the first channel to service the first BSS is not compatible with a particular hardware filter of the first radio, migrating the first BSS from the first radio to the second radio to service on the second channel, and providing the additional service on the first channel.

Abstract: Example implementations relate to a radio interrupt reboot. For example, an apparatus may comprise a first processing resource connected via an interface to a second processing resource. The first processing resource may execute instructions to receive an interrupt generated by a radio coupled to the second processing resource, increment a counter in response to receiving the interrupt during a configurable time interval, and determine that the counter has not been incremented during a threshold number of configurable time intervals. The first processing resource may execute instructions to reboot the first processing resource and the second processing resource in response to the determination that the counter has not been incremented during the threshold number of configurable time intervals.

Abstract: Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.

Abstract: An example access point may include a memory and a processor executing instructions from the memory to receive an instruction to start a scan on a different wireless communication channel than an operating channel of the access point; transmit a Clear To Send-to-self frame on the operating channel of the access point, to notify client devices associated with the AP and at least a neighboring AP that the operating channel is busy, wherein the control frame includes a basic service set color associated with the access point; scan on the different wireless communication channel subsequent to transmitting the Clear To Send-to-self frame; and defer a subsequent data transmission received from the client devices in response to the data transmission including the basic service set color associated with the access point.
