Abstract: The present disclosure describes a wireless network in which an access point determines and selects alternative devices to make transmissions for energy harvesting purposes. The access point includes a memory and a processor communicatively coupled to the memory. The processor determines, based on a proximity of a first device to a second device, that the second device should harvest energy from a message transmitted by the first device, determines a first basic service set (BSS) color that the first device and the second device should use for the second device to harvest energy from the message, and communicates, to the first device, an instruction to use the first BSS color when transmitting the message.

Abstract: Client cooperative troubleshooting may be provided. A first computing device may receive, from a second computing device, a troubleshooting request in accordance with a troubleshooting capability protocol. Then the first computing device may signal troubleshooting aid messaging indicating troubleshooting is being performed and defining troubleshooting aid data. The troubleshooting request may then be performed in accordance with the troubleshooting capability protocol. The troubleshooting aid data may be received from a third computing device.

Abstract: In one embodiment, a device sends data traffic to a gateway of a backhaul mesh network via a first wireless access point of the backhaul mesh network. The device maintains, while associated with the first wireless access point, an association with a second wireless access point of the backhaul mesh network by sending a frame to the first wireless access point that is relayed by the first wireless access point to the second wireless access point. The device makes a determination that additional data traffic should be sent to the gateway of the backhaul mesh network via the second wireless access point. The device sends, based on the determination, the additional data traffic to the gateway of the backhaul mesh network via the second wireless access point.

Abstract: In one embodiment, a client device enters an area having an overhead mesh of access points, 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 client device obtains an area-dependent communication schedule for the overhead mesh that is exclusive or partially-exclusive to the client device for the area. The client device sends, during an arbitrary timeslot of the area-dependent communication schedule, a pull request. The client device receives, from a particular access point in the overhead mesh, a packet in response to the pull request.

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.
