Abstract: According to one or more embodiments of the disclosure, an example process herein may comprise: identifying a power budget threshold to maintain existing mesh backhaul links in a mesh tree; determining an estimated power budget among potential mesh backhaul links in the mesh tree; performing a channel evaluation of each candidate channel available to establish a backhaul link in the mesh tree; and reconfiguring the mesh tree, in response to a modified power budget for the mesh tree, wherein reconfiguring is based on the estimated power budget and the channel evaluation.

Abstract: Adaptive guard interval calibration may be provided. A computing device may receive a first plurality of delay spread values. Each of the first plurality of delay spread values may respectively comprise an amount of time between when each of a respective first plurality Access Points (APs) receives a first tuning symbol from a first calibrating AP and when each of the respective first plurality APs receives a final multipath reflection of the first tuning symbol. Next, a first Guard Interval (GI) may be determined based on the first plurality of delay spread values. The first calibrating AP may then be provisioned with the first GI.

Abstract: An arrangement of three radios maybe provided. The three radios define first and second outer data links and a middle data link. Access to the arrangement of three radios can be biased to the middle data link in one direction upon a data transmission through the first and second outer data links being dominate in an opposite direction. Data transmission with enhanced multi-link single radio (eMLSR) client devices can be prioritized lower than data transmission with simultaneous transmit and receive radio (STR) client devices and non-simultaneous transmit and receive radio (NSTR) client devices. A radio can be configured for data transmission with a client device. The range of the radio is limited when the data traffic through the radio exceeds a determined number of bytes of data in a determined amount of 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: 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: Coordinated Frequency Division Multiplexing (FDM) Transmission Opportunity (TXOP) sharing may be provided by determining that at least two Access Points (APs) of a wireless network support coordinated FDM TXOP sharing. In response to the determination that the at least two APs support coordinated FDM TXOP sharing, at least one of: a first bias is applied to a channel assignment algorithm to promote an assignment of overlapping channels of the at least two APs, and a second bias is applied to the channel assignment algorithm to promote an assignment of adjacent channels of the at least two APs. Next, channels are assigned to the at least two APs based on an output of the channel assignment algorithm.

Abstract: Channel availability check optimization may be provided. A plurality of Pulse Repetition Intervals (PRIs) may be determined for a respective plurality of bursts on a respective plurality of frequencies. A list of at least a portion of the plurality of frequencies may be generated. The list may include a plurality of bias factors respectively indicating a probability that each of the respective plurality of bursts was a radar burst based on the respective plurality of PRIs. An Access Point (AP) may perform a plurality of preemptive Channel Availability Checks (CACs) on each of the respective plurality of frequencies on the list in order of highest probability to lowest probability based on the plurality of bias factors.

Abstract: Service cognizant radio role assignments may be provided. A computing device may receive a beacon message associated with a tag. Then, based on information derived from the beacon message, an optimum radio in a network may be determined to monitor the tag. The optimum radio may be associated with an Access Point (AP) comprising one of a plurality of APs in the network. The optimum radio associated with the AP in the network may then be provisioned to monitor the tag.
