Abstract: The disclosed embodiments provide for management of a Wi-Fi network in the presence of a high priority receiver. When a high priory receiver is identified, a portion of the Wi-Fi network that could potentially interfere with the high priority receiver is identified and steps are taken to reduce the probability of such interference. For example, some wireless transmitters may be switched to alternate channels to reduce the probability of interference. By sharing information relating to high priority receivers across a plurality of wireless transmitters, the disclosed embodiments provide for more efficient operation in the presence of high priority receivers when compared to methods that independently detect a high priority receiver at each wireless transmitter.

Abstract: Disclosed are methods and systems for improved wireless terminal roaming. In some embodiments, a management module determines access point density metrics for a plurality of centrally managed access points of a communications site. The density metric considers an average RSSI of access point signals received by other access points of the site, and each access point's contribution to the average. A determination of whether a particular wireless terminal roams is based on the density metrics of the source and target access point, as well as statistics relating to a current capacity of each of the access points. The disclosed embodiments may determine that a wireless terminal should transition/roam away from an access point even when that access point's RSSI value at the wireless terminal is above a threshold that would cause traditional methods to inhibit roaming.

Abstract: Methods and apparatus for automatically reconfiguring network parameters are described. Some embodiments identify communication channels that may interfere with higher priority equipment and deactivate communication channels that may cause harmful interference. Some APs are switched to 2.4 GHz communication channels. In some embodiments, AP operating parameters, such as transmission power are adjusted to reduce interference for higher priority receivers.

Abstract: Techniques are described for determining port misconfiguration between network devices. For example, a network management system comprises a memory and one or more processors in communication with the memory and configured to: obtain information associated with one or more ports of a plurality of network devices; determine, based on information associated with a port of a first network device of the plurality of network devices and information associated with a port of a second network device of the plurality of network devices that is connected to the port of the first network device, whether there is a port misconfiguration of the first network device or the second network device; and perform, based on the determination that there is a port misconfiguration of the first network device or the second network device, an action to remedy the port misconfiguration of the first network device or the second network device.

Abstract: Example network management systems, techniques, and computer-readable media are set forth herein. An example network management system is configured to obtain client activity data of one or more access point (AP) devices. The example network management system is configured to determine, based on the client activity data, an anomaly in a behavior of an AP device of the one or more AP devices based on at least one of a comparison to forecasted client activity data of the AP device or a comparison to client activity data of at least one peer AP device. The network management system is configured to perform, based on the determined anomaly in the behavior of the AP device, an action.

Abstract: Techniques are described for automatically configuring one or more settings of wireless radios within access point (AP) devices at a site based on wireless radio configuration settings for wireless radios within AP devices at manually tuned sites, i.e., “golden sites.” The techniques may automatically configure channel bandwidth settings of the wireless radios within the AP devices to optimize performance of wireless networks at the site. A system monitors operational parameters of the wireless radios within the AP devices at a site, identifies a class of wireless radios within AP devices at the golden sites that have similar operational parameters as one or more wireless radios within a particular AP device at the site, and automatically configures the settings of the wireless radios within the particular AP device at the site based on the settings associated with the identified class of wireless radios within AP devices at the golden sites.

Abstract: Techniques are described that detect areas with insufficient radio frequency (RF) coverage in a wireless network. A network management system (NMS) determines one or more service level expectation (SLE) metrics for each client device in a wireless network. The SLE metrics are aggregated to each access point (AP) in the wireless network, and each AP is assigned an AP score based on the aggregated SLE metrics. To identify potential coverage holes, the NMS groups APs having poor AP scores. If a root cause of the poor AP scores cannot be automatically resolved and if the poor AP scores persist for a predetermined period of time, the group of APs is determined to represent a true coverage hole. The NMS may generate a notification regarding recommended corrective actions to the customer and/or IT personnel.

Abstract: Techniques are described by which a network management system (NMS) receives, from a plurality of access points (APs) configured to provide a wireless network, received signal strength indicator (RSSI) values. The NMS generates, based on the RSSI values, a graph of the plurality of APs, wherein the graph of the plurality of APs includes a plurality of clusters, wherein each cluster comprises a subset of the plurality of APs that are grouped based on strength of connectivity between the subset of the plurality of APs. The NMS generates, based on the graph, an upgrade plan to upgrade the plurality of APs, wherein the upgrade plan comprises a plurality of batches, wherein each batch includes a selection of at least one AP from each of one or more of the plurality of clusters. The NMS sends the upgrade plan to an orchestrator to execute the upgrade plan.
