Abstract: Systems and methods for grouping client devices for uplink multi-user transmission are provided. Client device groups may be determined based on at least one of traffic compatibility/similarity, client device class compatibility/similarity, and uplink pathloss similarity. A target received signal strength measured by an AP with which client devices in the client device groups communicate and an appropriate modulation coding scheme rate to be used by the client devices may be determined and set for the client devices. The modulation coding scheme rate can be adjusted based on feedback regarding successful data packet reception at the AP from each of the client devices.

Abstract: Embodiments are directed to automatic location of access points in a network. An embodiment of one or more non-transitory computer-readable storage mediums includes instructions for transmitting a request from a computing device to multiple access points in a network to determine a distance between each pair of access points of the multiple access points; receiving at the computing device the determined distances between each pair of access points; generating a proximity matrix containing the determined distances between each pair of access points; solving the proximity matrix to automatically generate a set of locations for the multiple access points; and orienting the generated set of locations for the multiple access points based on known locations of one or more anchor points in a subset of the access points.

Abstract: Systems and methods for assigning BSS colors in a deployed wireless area network (WLAN) include identifying a plurality of APs of an external wireless network operating on a same channel as a deployed AP of a deployed wireless network; selecting as a subset of the plurality of APs of the external wireless network those APs of the external wireless network based on expected interference; grouping the APs of the subset of the plurality of APs by a basic service set (BSS) color used by each of the plurality of identified APs of the external wireless network to form AP BSS color groups; calculating an airtime utilization for each AP color group; and selecting a BSS color using the calculated airtime utilization and assigning the selected BSS color for use by the deployed AP of the deployed wireless network.

Abstract: In some examples, a non-transitory machine-readable medium can include instructions executable by a processing resource of a network device to: receive a first message on a communication band from a first wireless client device; determine a capability complying with a particular wireless specification of the first wireless client device based on information in the first message; split communication channels on the communication band into a first communication channel group and a second communication channel group; and operate the first communication channel group in accordance with the particular wireless specification and the second communication channel group in accordance with other wireless specifications.

Abstract: Systems and methods are provided for improving geolocation services, like GPS, using network device measurements. For example, a plurality of access points (APs) or other network devices may be implemented in a network environment and constructed with a GPS chip. Range measurements can be collected from these network devices and incorporated with the GPS locations using various methods described herein to improve the overall location determination of these devices.

Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.
