    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: 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 optimize wireless local area network access point beam settings. A method includes, during a survey period, causing a first access point and a second access point in a wireless local area network, to simultaneously transmit survey transmissions according to a predetermined sequence of transmission states, receiving, from a survey station that received the survey transmissions during the survey period, telemetry associated with the survey transmissions, the telemetry including a location of the survey station when the survey station received the survey transmissions, and after the survey period, controlling, based on the telemetry associated with the survey transmissions, the first access point to operate according to a first transmission state from among the transmission states and the second access point to operate according to a second transmission state from among the transmission states.

    Abstract: A method for adaptive presence-based radio configuration of access points in a venue includes defining a number of regions in the venue in which access points are deployed, each region having a center point, and assigning a first access point to a first region, positioned at the center of the first region. The method also includes affecting a first energy level in the first region, which corresponds to a power of a transmit signal emitted by the first access point, and assigning to the first region a configurable capacity value that determines an acceptable overlap constraint between the first energy level of the first region and an energy level of a neighboring region. The method further includes generating data describing a tessellation graph in which a possible map of the access points is formed using an iterative descent process based on the first energy level and the overlap constraint.
