Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

Abstract: The present disclosure is directed to the use of active feedback from client devices to limit/regulate transmission power control of access points from the perspective of the client device. The instant transmission power control beneficially ensures that clients located at a cell edge still receive sufficient coverage from access points and have sufficient overlap with adjacent cells for seamless roaming for the wireless stations while minimizing co-channel interference. In some embodiments, the present disclosure beneficially leverages 802.11h TPC Constraint to dynamically report client's view of the RF environment and cell size estimation.

Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Each subchannel corresponds to a distinct frequency chunk with a respective plurality of subcarriers. Radar is detected on a first subchannel. In response, a selection is made between (i) redefining the channel and (ii) puncturing the first subchannel while continuing to use all other subchannels. Puncturing the first subchannel includes muting subcarriers on the first subchannel. Redefining the channel includes removing multiple subchannels from the channel. The selection is based at least in part on one or more factors that provide indications as to whether puncturing would be efficient and/or effective. The access point continues to communicate wirelessly with the one or more client devices in accordance with the selection.

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.

The flexible radio assignment algorithm manages the redundant radio in the selected AP to mitigate co-channel interference in a frequency band.

The service causes a wireless access point to change to a different wireless channel, based on the predicted channel usages by the radar.

Abstract: In one embodiment, a neighbor access point list is obtained. Statistics are maintained for a current access point that a client is currently associated with, including previous access points previous clients have roamed from prior to associating with the current access point, and next access points the previous clients associated with. The neighbor access point list for the client is optimized, by determining one or more previous clients that associated with a same previous access point as the client and prioritizing access points in the optimized neighbor access point list, based on the next access points the one or more previous clients associated with. The optimized neighbor access point list is sent to the client.

Abstract: Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.

Abstract: In an example embodiment, a neighbor radio/access point (AP) list is obtained. The neighbor AP list is optimized for a client that is associated with a current access point. The list may be optimized based on any one or combination of techniques, including but not limited to roaming patterns of previous clients that were associated with the current access point, radio frequency metrics, bandwidth requirements for the client, and/or any other suitable criteria. In particular embodiments, requests from the client to associate with an access point that is not on the optimized neighbor AP list may be denied.
