Abstract: An example network device may include a processor to assign resource units (RUs) for a multicast frame and a unicast frame, wherein the assigned RUs include a first RU corresponding to the multicast frame and a second RU corresponding to the unicast frame, and wherein a client device corresponding to the unicast frame is excluded in a subset of client devices corresponding to the multicast frame; and transmit the multicast frame and the unicast frame in a same duration by the first RU and the second RU, respectively.

Abstract: 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.

The processor is further to perform: sending a request to a remote server to acquire the cloud key; and forwarding the acquired cloud key to the TPM for storage.

In a first example, a wireless networking device includes first radio and a second radio communicatively coupled to a wired network communication interface. The first and second radios have different operational parameters for bandwidth of transmission and other factors.

Based on that determination the single data communication channel may be transitioned to be received via the second radio. Each radio may maintain an active/backup status or perform load balancing to provide transmission of the single data communication channel.
