    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 mobile system receives a group identifier for wireless access points associated with a pathway via which the mobile system is to travel. The mobile system receives, during travel of the mobile system along the pathway, beacons from a plurality of wireless access points. Each of the plurality of wireless access points indicates its group identifier in its beacon. The mobile system selects, based on the beacons, a particular access point from among the plurality of wireless access points for roaming, in part by giving preference to any access points in the plurality of wireless access points having a group identifier that matches the group identifier associated with the pathway. The mobile system wirelessly roams to the particular access point.

    Abstract: In one embodiment, a controller predicts an occurrence of an event in a wireless network, based in part on a movement of a mobile node of the wireless network. The controller initiates application of network-layer forward error correction encoding to a stream of packets to be sent during the event between the mobile node and an access point of the wireless network, to form one or more encoded packets. The controller causes the one or more encoded packets to be transmitted in conjunction with the stream of packets during the event. The controller ceases application of the network-layer forward error correction encoding after the event has occurred.

    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.
