Abstract: Dynamic spectrum access mode based on station capabilities is provided by categorizing functionalities of Access Points (APs) and mobile stations (STA) in a wireless network; identifying interference induced by external signaling devices on channels in the wireless network; calculating an impact factor of the interference based on proximity of the external signaling devices to the wireless network, a pattern of the external signaling devices, and an extent of overlap with frequencies used by the external signaling devices and the wireless network; and in response to identifying a given STA that is paired with a given AP in the wireless network, wherein the given STA and the given AP are both categorized as being capable of both multilink communications and preamble puncturing, assigning network resources for the given STA to communicate with the given AP via one of multilink communications or preamble puncturing based on the impact factor of the interference.

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: Techniques are disclosed for determining one or more radio resource management (RRM) input parameters. The one or more RRM input parameters are determined based on a line of sight (LOS) estimate between two wireless stations (STAs). A plurality of RRM values are generated based on the one or more RRM input parameters. A wireless connection is established between a first wireless access point (AP) and a first STA using the RRM values.

Abstract: A network system comprises a plurality of access points (APs) and a distributed cache. The distributed cache is formed using memory in the plurality of APs. The plurality of APs are configured to measure telemetry data and store the telemetry data in the distributed cache. One of the plurality of APs is assigned as a controller AP configured to assign, based on the telemetry data stored in the distributed cache, multiple APs of the plurality of APs to different roles to analyze the plurality of APs and update resource configurations of the plurality of APs.

Abstract: Techniques for a machine learning event-driven radio resource management (ED-RRM) module which provides analysis of interference events in a network system are described. The network system reacts to the detection of interference in a network system and uses multiple input parameters to determine a type of device creating the interference, a predicted duration of the interference, and an ED-RRM decision on whether to activate the radio resource management (RRM) processes to alter the network transmission or block the RRM processes to conserve system resources for the network system.

Abstract: An algorithm for determining redundant radios in APs is disclosed. The algorithm first performs a coverage peak flattening algorithm to predict an impact to the total coverage area if a radio in a selected AP does not transmit signals in a frequency band. If the impact to the total coverage area is acceptable, the algorithm then performs a multi-point check algorithm to determine whether the radio in the selected AP is redundant in the frequency band. After determining that the radio in the selected AP is redundant in the frequency band, the algorithm transforms the redundant radio into various services based on the network deployment and user preference.

Abstract: Techniques for dynamic RF site configuration are provided. Historical association data is collected from a plurality of access points in a physical environment, and a machine learning model is trained to predict future association events, based on the historical association data. Current association data is then collected from the plurality of access points, and at least one predicted association event is generated by processing the current association data using the trained machine learning model. The plurality of access points is allocated to a plurality of radio frequency (RF) sites based on the at least one predicted association event. Finally, at least one of the plurality of RF sites is configured based on the predicted association event.
