Abstract: In one embodiment, a service maintains a plurality of machine learning-based client behavioral models. Each behavioral model models wireless client behavior of a particular client type and configuration. The service selects one or more of the behavioral models to emulate the modeled one or more wireless client behaviors in a wireless network. The service controls, by using the selected one or more behavioral models, one or more emulation points in the wireless network to generate wireless client traffic in the wireless network that exhibits the modeled one or more wireless client behaviors. The service obtains performance metrics from the wireless network associated with the generated wireless client traffic.

Abstract: Embodiments herein describe control logic for seamlessly switching client devices between radios co-located on the same network device or between radios located on different network devices that have overlapping coverage areas. In one embodiment, the radios are assigned different channels in the same frequency band. To move the client devices between the radios, one of the radios transmits a Channel Switch Announcement (CSA) which instructs the client devices serviced by a first radio to switch to a channel assigned to a second, different radio. For example, the CSA may be used when the first radio fails, is upgraded, performs a Channel Availability Check (CAC), is overloaded, and the like. After the CSA is transmitted, the second radio spoofs the service identifier of the first radio so to the perspective of the client devices, they are still communicating with the first radio.

Abstract: A wireless access point that serves one or more wireless client devices in a wireless network determines that at least one particular client device that is associated to the wireless access point should not be associated to the wireless access point. The wireless access point transmits frames so that they are received at the particular client device with reduced strength so as to provoke the particular client device to transition from the wireless access point.
