A method including identifying that a client device is physically presented within a coverage area corresponding to a network is provided. The client device is associated with a user having a user credential to log in to the network, and the method includes determining that the client device has not requested to log in to the network using the user credential, and generating an alert to an administrator of the network responsive to both (1) that the client device is physically presented within the coverage area and (2) that the client device has not requested to log in to the network.

Detecting network connectivity anomalies with presence analysis

An example of a system may include a computing device, communicatively coupled to a network device, including: a processing resource; and a memory resource. The memory resource may store instructions executable by the processing resource to: track a movement of a first mobile device through a physical environment based on a first wireless signal received, at the network device, from the first mobile device; track a movement of a second mobile device through the physical environment based on a second wireless signal received, at the network device, from the second mobile device; associate the first mobile device with the movement of the second mobile device based on a correlation between the tracked movement of the first mobile device and the tracked movement of the second mobile device; and assign, based on the association, an action to be executed upon a next detection of the first mobile device by the network device.

Device movement correlations

According to examples of present disclosure, a network device may group a first subset of client devices for beamforming transmissions using multi-user multiple-input multiple-output (MU-MIMO), and also group a second subset of client devices associated with the two or more basic service sets for simultaneous data transmission using multi-user orthogonal frequency-division multiple access (MU-OFDMA). The subset of client devices within the same group may be associated with different basic service sets.

Enhancing MU-MIMO to group clients across multiple BSSIDS for a physical radio

Example method includes: receiving, by a network device, a plurality of notifications from a plurality of access points in a wireless local area network (WLAN), each notification indicating detection of a particular radar event on a particular wireless communication channel; identifying, by the network device, at least one access point operating on the particular wireless communication channel beside the plurality of access points that fails to detect the particular radar event; and transmitting, by the network device, instructions to the at least one access point, wherein the instructions cause the at least one access point to switch to operate on a different wireless communication channel.

Identifying as access point operating on a particular wireless communication channel that fails to detect a particular radar event

MU-MIMO provides a mechanism for a wireless network device to transmit to multiple client devices at the same time. When employing MU-MIMO, a network device may group two or more associated client devices, and transmit beamformed signals to each group. In some implementations, a network device may initiate channel sounding. Channel sounding may include transmitting sounding frames to client devices associated with two or more basic service sets. Channel sounding may facilitate beamforming transmissions to client devices associated with the two or more basic service sets. The network device may receive feedback frames from client devices associated with the two or more basic service sets. A feedback frame may indicate how a sounding frame was received. In some implementations, the network device may further construct a feedback table from the feedback frames. The feedback table may facilitate grouping of the client devices for beamforming transmissions.

Enhancing MU-MIMO to group clients across multiple BSSIDs for a physical radio

The present disclosure discloses a method and network device for dynamically prioritizing user connections on network. The disclosed system identifies a priority class associated with a client device prior to an initial connection from the client device to a network, and reserves access to a network resource for the client device based on the priority class prior to the initial connection. Specifically, the system evaluates a total capacity of the network resource and an anticipated usage of the network resource by the client device associated with the priority level. Then, the system will reject requests for accessing the network resource received from other client devices prior to the client device associated with the priority level accesses the network resource.

Method and system for dynamically prioritizing user connections on network

The present disclosure discloses a distributed radio management system that is capable of dynamically tuning a radio antenna to a particular radio frequency channel and/or radio frequency band. The disclosed network device includes a transceiver, an antenna, and a component on a wireless signal path between the transceiver and the antenna. The component includes functionality to dynamically switch between processing signals corresponding to a first radio frequency band and processing signals corresponding to a second radio frequency band. Moreover, the component also may include functionality to dynamically switch between processing signals and refraining from processing wireless signals that are received by the component.

Distributed radio management

The present disclosure discloses a method and network device for efficient frame aggregation. Specifically, a network device queues a first set of packets until one of the first set of aggregation limits is detected. The network device then transmits the first set of packets, and receives feedback information. Then, the network device modifies the first set of aggregation limits to obtain a second set of aggregation limits based on the feedback information. The network device queues a second set of packets until one of the second set of aggregation limits is detected, and then transmits the second set of packets. Also, the network device determines whether a received packet has a particular characteristic. If so, the network device transmits the first set of packets before at least one of the first set of aggregation limits is detected.
