Abstract: Example method includes: receiving, by a first access point, a plurality of beamforming feedback frames from a plurality of client devices in a WLAN; overhearing, by the first access point, a first beamforming feedback frame from a second access point; calculating, by the first access point, a second beamforming feedback frame in response to receiving a sounding frame transmitted from the second access point in the WLAN; selecting, by the first access point, a first subset of the plurality of client devices and the second access point as members of a MU-MIMO group; changing, by the first access point, a steering matrix corresponding to the MU-MIMO group based on both the received plurality of beamforming feedback frames and the calculated beamforming feedback frame to allow the first access point and the second access point transmit on a particular wireless communication channel simultaneously without interfering each other.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A dynamic BSS color feature for co-hosted virtual access points is described. An example of a storage medium includes instructions to operations including enabling, by an access point, a dynamic basic service set (BSS) color feature for operation with multiple virtual access points (VAPs) hosted by the access point; switching a parameter of the access point to indicate that no co-hosted BSS is present; assigning a different BSS color to each of the VAPs; performing access point operations, including utilizing the assigned BSS colors for transmissions relating to any of the VAPs; and disabling the dynamic BSS color feature upon occurrence of one or more conditions.

Abstract: Example implementations relate to an access point (AP) that can via up from power save mode via a including Bluetooth low energy (BLE) system-on-chip (SoC) within the AP. The AP can include a power source, a power reset logic component in communication with the power source, a BLE SoC, a processor, and a non-transitory memory resource instructions executable by the processor that signals the AP is in a power save mode, receives an indication, via the BLE SoC, to wake up the AP, and wake up, via the BLE SoC, the AP in response to receiving the indication.

Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.
