Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.

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: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

Abstract: The present disclosure is related to systems and methods for detecting and disabling operations of access point impersonators in a network. In one aspect, a method includes receiving, at a network controller of a network, beacon reports from a plurality of access points; determining, by the network controller, one or more target areas with at least one potential access point impersonator operating therein; sending, by the network controller, on-demand beacon requests to one or more of the plurality of access points with corresponding coverage areas overlapping with the one or more target areas; receiving, at the network controller, responses to the on-demand beacon requests from the one or more of the plurality of access points; and determining, by the network controller, at least one access point impersonator based on the responses.

Abstract: In one embodiment, a method is performed. A first wireless access point (AP) device may generate a timing synchronization frame. The timing synchronization frame may include a target beacon transmission time (TBTT) associated with the first wireless AP device. The first wireless AP device may transmit the timing synchronization frame to a second wireless AP device. The first and second wireless AP devices may be synchronized using the timing synchronization frame.

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: Presented herein are techniques for using mobile client density to compensate for variations in path loss between neighboring access points. In one example, a device (e.g., wireless controller) determines one or more mobile client density variation trends in a wireless network location and determines one or more neighbor message power variation trends between at least first and second access points within the wireless network location over a time period. The device generates one or more correlation bias factors using the mobile client density variation trends and the neighbor message power variation trends over the time period. The device determines a path loss between at least the first and second access points using the correlation bias factor.

Abstract: Presented herein are techniques to allocate use of controlled wireless spectrum. A method includes receiving, from a wireless local area network service provider, a request for wireless local area network spectrum for a future time window, wherein the wireless local area network spectrum is subject to automated frequency coordination, in response to the request, sending, to an incumbent that uses the wireless local area network spectrum, a query consistent with the request for the wireless local area network spectrum for the future time window, receiving, from the incumbent, in response to the query, a grant to use the wireless local area network spectrum for the future time window, and in response to receiving the grant, sending permission to the wireless local area network service provider to use the wireless local area network spectrum for the future time window.
