Abstract: According to one or more embodiments of the disclosure, a device receives data regarding wireless communications between a wireless access point and a client. The device evaluates, based on the data, motion of the client relative to the wireless access point. The device makes, based on the motion of the client relative to the wireless access point, a determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point. The device adjusts the wireless communications, based on the determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point.

Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

Abstract: In response to receiving a probe request from a mobile client, an access point determines whether it should suppress a probe response. The access point receives a probe request from a wireless client device, and prepares a probe response to respond to the probe request. The access point determines whether the wireless client device is likely to associate with the wireless access point. Responsive to a determination that the wireless client device is unlikely to associate with the wireless access point, the access point suppresses the transmission of the probe response.

Abstract: Presented herein are techniques for using uplink transmissions from devices (e.g., wireless tags, clients, etc.) to determine a path loss between neighboring access points. In one example, a wireless controller obtains receive signal strength information of uplink transmissions received at neighboring access points in a wireless network. The wireless controller determines an effective path loss between the neighboring access points based on the receive signal strength information for the uplink transmissions received at the neighboring access points. The wireless controller also performs radio resource management operations in the wireless network using the effective path loss determined based on the uplink transmissions received at the neighboring access points.

Abstract: Presented herein are techniques to allocate use of controlled wireless spectrum. A method includes receiving, from a wireless local area network service provider, a request for wireless local area network spectrum for a future time window, wherein the wireless local area network spectrum is subject to automated frequency coordination, in response to the request, sending, to an incumbent that uses the wireless local area network spectrum, a query consistent with the request for the wireless local area network spectrum for the future time window, receiving, from the incumbent, in response to the query, a grant to use the wireless local area network spectrum for the future time window, and in response to receiving the grant, sending permission to the wireless local area network service provider to use the wireless local area network spectrum for the future time window.

Abstract: Techniques herein facilitate dynamic configuration of a wireless local area network (WLAN) for large public venue (LPV) environments. In one example, a method may include providing an initial configuration for access points APs of a WLAN for an event at an LPV based on a profile for the event, a location of each AP for the venue, and anticipated demand at the APs; determining, for a particular time for the event, a distribution of wireless devices and channel support capabilities of the wireless devices different locations for the LPV; and providing an updated configuration for one or more APs at the one or more locations for the venue based on the distribution of the wireless devices and the channel support capabilities of the wireless devices determined for the particular time for the event at the LPV.

Abstract: A method for providing adaptive radio transmit power based on antenna pattern and elevation tilt measured through an accelerometer is provided. The method includes estimating an orientation of a wireless device using an orientation sensor integrated in or on the wireless device, and determining an adjustment factor for a transmitter of the wireless device based on the orientation. The method further includes adjusting output power of the transmitter of the wireless device based on the adjustment factor.

Abstract: Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.

Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may establish Multi-Access Point (AP) coordination between at least a first AP and a second AP. The first AP can determine an uplink operation is scheduled. When an uplink is scheduled, the first AP can switch its antenna to a narrow beamwidth. The first AP can then receive uplink transmissions from at least a client in the coverage area of the narrow beamwidth. After the uplink transmission, the first AP can then switch the antenna to a larger beamwidth for a next Multi-AP coordination operation.

Abstract: In one illustrative example, a device configured for use in a wireless local area network (WLAN) may cause a spatial reuse (SR) adjustment to be performed based on data received from a multi-user receiver procedure for the blind detection and demodulation of colliding packets from multiple stations. This procedure may be performed by one or more access points (APs) and/or distributed sensor nodes, each having such a multi-user receiver. The procedure may involve receiving and decoding, over a channel, a first spatial stream from a first device of a first base service set (BSS) color; simultaneously receiving and decoding, over the channel, a second spatial stream from a second device of a second BSS color (i.e. an overlapping BSS or “OBSS”); and calculating a signal-to-interference ratio (SIR) based on signal levels associated with the streams. The SR adjustment may involve adjusting an OBSS Packet Detect (PD) (OBSS-PD) threshold.
