摘要： The present disclosure discloses a method and digital device for improving performance in discovery stage of fast roaming. A disclosed digital device switches from a first wireless communication channel to a second wireless communication channel; transmits, on the second wireless communication channel, a request message comprising a designated field; and switches from the second wireless communication channel to the first wireless communication channel prior to receiving a response message corresponding to the request message on the second wireless communication channel. A network device receives the request message from a client device on the second wireless communication channel. The request message is associated with a first signal strength level. The network device determines that the request message includes a designated field; and transmits a response message to the client device via a different communication interface, such as a wired or wireless distribution system, or the client device's data transmission channel.

摘要： An example method of controlling a wireless access point may include causing the wireless access point to identify any groupings of contiguous non-protocol FFT bins of a wireless channel in which all of the non-protocol FFT bins in the grouping have respective signal strength values exceeding a first threshold, and a bandwidth of the grouping does not exceed a second threshold. The method may also include causing the wireless access point to identify any resource units of the wireless channel that overlap with any of the identified groupings. The method may also include causing the wireless access point to, in allocating the resource units to client devices for an OFDMA communication, skip the identified resource units.

摘要： An example method of controlling a wireless access point may include associating accumulated-channel-resource-consumption variables with, respectively, resource consumers of the wireless access point. The method may further include, for wireless communications of the wireless access point: determining a number of spatial streams effectively consumed by the respective wireless communication; determining an operational bandwidth effectively consumed by the respective wireless communication; determining a duration of the respective wireless communication; determining a channel-resource-consumption amount for the respective wireless communication based on the number of spatial streams effectively consumed by the respective wireless communication, the operational bandwidth effectively consumed by the respective wireless communication, and the duration of the respective wireless communication; and determining values for the accumulated-channel-resource-consumption variables by accumulating the channel-resource-consumption amounts per resource consumer. The method may further include determining whether to impose channel access restrictions on the resource consumers based on their respective accumulated-channel-resource-consumption variables.

摘要： In one example a computer implemented method comprises receiving, at an access point of a wireless network, a multicast/broadcast frame which identifies one or more stations associated with the access point as a recipient for the multicast/broadcast frame, and in response to a determination that at least one station of the one or more stations identified as a recipient for the multicast/broadcast frame is in an inactive state, determining a beacon slot time for a transmission of the multicast/broadcast frame from the access point, in response to a determination that at least one of the one or more stations in an inactive state will miss the beacon signal, converting the multicast/broadcast frame to a unicast frame, and holding a copy of the unicast frame to be transmitted to the at least one of the one or more stations in an inactive state that will miss the beacon signal.

摘要： Systems and methods are provided for upgrading wireless network devices, such as access points (APs). When a first AP needs an upgrade, a network controller of the first AP may identify and select a neighbor AP. The radio(s) of the neighbor AP can be split into multiple logical radios, at least one of which includes a backup virtual AP (VAP). The backup VAP can support client devices originally supported by the first AP, allowing those client devices to roam to the neighbor AP while the first AP is upgrading, and without needing to re-associate with the neighbor AP. From the client device perspective, it appears as though they are still being supported by the first AP. Upon upgrading the first AP, the client devices can roam back to the first AP (without needing to re-associate with the first AP). No downtime is experienced, and no RF holes are generated.
