Abstract: In one embodiment, an access point of an overhead mesh of access points in an area selects a range of client identifiers. The access point sends, via a beam cone transmitted in a substantially downward direction towards a floor of the area, a trigger signal that includes the range of client identifiers and prompts client devices having identifiers in that range to send best effort transmissions towards the overhead mesh. The access point detects a collision between the best effort transmissions of the client devices. The access point adjusts the range of client identifiers so as to avoid future collisions between the best effort transmissions of the client devices.

Abstract: In one embodiment, a device identifies a plurality of paths in a wireless backhaul network between a gateway and a plurality of access points that provide wireless connectivity to a mobile system. The device determines a movement of the mobile system. The device determines, based on the movement of the mobile system, that a particular path in the plurality of paths is not needed to provide wireless connectivity to the mobile system. The device causes one or more networking nodes along the particular path to enter into a power saving mode.

Abstract: In one embodiment, a device obtains location data indicative of a location of a mobile system relative to a base station of a wireless network. The device predicts, based on the location data, a drop in received signal strength indicator as the mobile system approaches the base station. The device determines, based on the drop in received signal strength indicator or throughput that will occur as the mobile system approaches the base station. The device prevents the mobile system from communicating with the base station during the ban.

Abstract: In one embodiment, a mobile node in a wireless network determines a physical location of the mobile node. The mobile node obtains telemetry data. The mobile node makes a comparison between the physical location of the mobile node and a location-based telemetry reporting policy. The mobile node sends, based on the comparison, the telemetry data via the wireless network.

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

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 assigns the access points to access point groups. The controller generates communication schedules for the access points such that each access point in an access point group is on a common channel and only one of neighboring directional transmitters of access points in that group is able to transmit at any given time. The controller sends the communication schedules to the access points forming the overhead mesh of access points in the area.

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.
