Claim 0:
1. A method comprising:
selecting, by an access point of an overhead mesh of access points in an area, a range of client identifiers;
sending, by the access point and 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;
merging, by the access point, contiguous ranges of client identifiers to be included in a single trigger signal, based on a determination that no responses were received in response to trigger signals for the contiguous ranges of client identifiers;
detecting, by the access point, a collision between the best effort transmissions of the client devices; and
adjusting, by the access point, the range of client identifiers so as to avoid future collisions between the best effort transmissions of the client devices.
