    Abstract: An epoch scheme for Station (STA) privacy and, specifically, a structured Media Access Control (MAC) address rotation schedule for STAs may be provided. Providing an epoch scheme for STA privacy can include determining epoch parameters for a STA, the epoch parameters comprising a minimum epoch period duration and a maximum epoch period duration. The epoch parameters are sent to the STA, wherein the STA is operable to rotate a MAC address each epoch period at a time between the minimum epoch period duration and the maximum epoch period duration. A mapping of the STA and the MAC address can be updated each epoch period.

    Abstract: A system and a method to dynamically reprovision network devices may include a first network device configured to reprovision a second network device in accordance with a specific location of the second network device in a predefined area. The first network device may be configured to sense the second device at the specific location in the predefined area, identify reprovisioning parameters associated with the specific location, and provide the reprovisioning parameters to the second network device. In turn, the second network device may be configured to perform one or more roles associated with the specific location in the predefined area based at least in part upon information in the reprovisioning parameters.

    Abstract: A method is provided that is performed in a wireless network to detect a rogue wireless device. The method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first Media Access Control (MAC) address that is also used by a valid wireless device in the wireless network. When a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its MAC address. After the valid wireless device has changed its MAC address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. The method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first MAC address.

    Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller determines coverage areas on the floor of the area for the one or more directional transmitters of the access points in the overhead mesh. The controller generates, based on the coverage areas, alternating communication schedules for the access points such that a client device at any given location on the floor of the area is within range of a plurality of receiving access points in the overhead mesh and at least one transmitting access point in the overhead mesh at a certain point in time. The controller sends the communication schedules to the access points.

    Abstract: Backscatter Device (BKD) placement and placement calibration may be provided. A plurality of ambient energy sources of a Three-Dimensional (3D) space may be caused to transmit charging frames for Backscatter Devices (BKDs). Each of the charging frames may include a payload having a Media Access Control (MAC) address of transmitting ambient energy source. An amount of ambient energy received from the charging frames of the plurality of ambient energy sources and each contributing source may be received from survey devices placed at positions along a sub-space of the 3D space. The amount of ambient energy available from each contributing source at each positions along the sub-space per predetermined time period may be predicted based on the amount of ambient energy received from the plurality of ambient energy sources.

    Abstract: Backscatter Device (BKD) placement and placement calibration may be provided. A plurality of ambient energy sources in a Three-Dimensional (3D) space may be identified and mapped. Each of the plurality of ambient energy sources may be categorized as one of the following: a stationary and controllable ambient energy source, a stationary and uncontrollable ambient energy source, and a mobile ambient energy source. An amount of ambient energy available at each of a plurality of sub-spaces of the 3D space may be determined. The amount of ambient energy available at each of the plurality of sub-spaces may be determined by determining a first amount of ambient energy that is continuously available and a second amount of ambient energy that is likely available at each of the plurality of sub-spaces of the 3D space.
