Examples described herein relate to a method for establishing a backup connectivity between a sensor and a management system. The sensor may be deployed in an IT infrastructure and configured to execute a one or more predetermined evaluations for the IT network and generate corresponding evaluation result. Thereafter, the sensor may determine whether a connection between the sensor and the management system via a primary connectivity is unsuccessful. In response to determining that the connection between the sensor and the management system via the primary connectivity is unsuccessful, the sensor may establish a backup connectivity by successfully connecting to an available wireless network using a security credential received by the sensor upon successful verification of public key information of the sensor via an authentication server. The sensor then transmits the evaluation result to the management system via the backup connectivity.

Systems and methods are provided for zero-touch provisioning of devices, such as sensors, on a network. When a device is unable/cannot access a network via Ethernet, cellular, or near field communications capabilities resident on the device, the device can alternatively be provisioned via an intermediate network device, such as an access point using, e.g., Device Provisioning Protocol or Wi-Fi EasyConnect. A cloud-based network management system may receive a device's bootstrapping information during or after manufacturing of the device. Ultimately, the device, via the intermediate network device, is able to communicate with a back-end, cloud-based network insight system from which configuration parameters for the device may be obtained.

Secure and adaptive mechanism to provision zero- touch network devices

Systems and methods are provided for adaptively enabling and disabling spatial reuse and adapting BSS color assignments based on various factors associated with a wireless network. A first AP in a wireless network can identify a second AP in a wireless network. The first AP and the second AP may be using the same wireless channel in the wireless network. The first AP can determine a signal strength, such as a received signal strength indicator (RSSI), associated with the second AP. The first AP can adapt its spatial reuse and BSS color assignment according to the signal strength and a signal strength threshold. By adaptively enabling and disabling spatial reuse and adapting BSS color assignments, the disclosed systems and methods provide for improved reuse of wireless mediums while avoiding collisions.

Adaptive spatial reuse

Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

Resource unit assignment for selective fading

Systems and methods are provided for discoverability detection of network services. The present disclosure provides for a cloud-based network insight server that collects performance information of a network and a network agent, communicating with the cloud-based network insight server, that monitors discoverability of network services hosted by devices on the network. The network agent receives configuration information from the cloud-based network insight server and transmits discoverability states of the devices to the cloud-based network insight server based on executing a service discovery process through an access point on the network.

Service reachability detection

Systems and methods are provided for opportunistic spatial reuse. In various embodiments, the disclosed systems and methods provide for mechanisms for enabling and disabling spatial reuse in a wireless network as appropriate based on the deployment of the wireless network. In some embodiments, spatial reuse can be enabled and disabled based on various factors, such as channel utilization. In some embodiments, spatial reuse can be enabled and disabled as appropriate for various types of traffic in a wireless network. For example, spatial reuse can be enabled and disabled for downlink traffic (e.g., traffic from an access point to a client device), for uplink traffic (e.g., traffic from a client device to an access point), for multicast or broadcast traffic (e.g., traffic distributed to multiple recipients), or for certain modes of transmission (e.g., single user beamformed transmission, Dual Carrier Modulated transmission).

Opportunistic spatial reuse

Systems and methods are provided for aggregating Media Access Control (MAC) Protocol Data Units (MPDUs) destined for different peers, and may have the same or different source address information, e.g., within the same or across different virtual access points (VAPs). For example, trigger frames used to signal to devices which subchannel(s) those devices can utilize, may be aggregated. For example, a multi-VAP/multi-device block acknowledgement for acknowledging packets transmitted to devices belonging to different VAPs can be sent as an aggregated MPDU.
