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: Systems and methods for spatial reuse in a deployed wireless area network (WLAN) include identifying a plurality of competing APs of an external wireless network operating on a same channel as a deployed AP of a deployed wireless network; examining the received signal strength indicator (RSSI) of the identified plurality of competing APs of the external wireless network; filtering out selected one or more of the identified plurality of competing APs of the external wireless network based on their respective RSSIs to arrive at a filtered set of competing APs; and augmenting a spatial reuse group (SRG) of the deployed AP to include the APs in the filtered set of competing APs in the SRG.

Abstract: Systems and methods for providing low latency connection by a network device is described herein. Upon receiving a request for a low latency connection from a client device, a lower frequency filter in a primary 6 GHz radio, a secondary 6 GHz radio and an upper frequency filter in the secondary 6 GHz radio may be enabled. A transition band between the lower frequency filter and the upper frequency filter may be enabled such that there is no interference between a primary frequency channel allowed by the lower frequency filter and a secondary frequency channel allowed by the upper frequency filter. An operating frequency channel of an existing communication session with the client device may be determined. Based on the operating frequency channel, the primary frequency channel and the secondary frequency channel may be determined to provide a first communication connection and a second communication connection to the client device.

Abstract: Systems and methods are provided for determining, at a beamformee, to transmit data signals from transmitting spatial streams at one or more beamformers. Next, a gain resulting from an uplink transmit beamforming protocol may be determined to exceed an overhead of the transmit beamforming protocol. In response to the determination, the uplink transmit beamforming protocol may be conducted. This protocol includes, transmitting trigger frames to the beamformers to obtain channel data regarding channels between each of the transmitting antennae and the active receiving antennae, receiving responses to the trigger frames from each of the beamformers, generating the channel data based on the received responses, feeding back the channel data to each of the beamformers, scheduling the uplink transmit beamforming protocol based on the channel data, and receiving an integrated data signal from the beamformers based on a processing of the data signals via the uplink transmit beamforming protocol.

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: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.
