Claim 9:
10. An apparatus, comprising:
one or more network interfaces;
a processor coupled to the one or more network interfaces and configured to execute one or more processes; and
a memory configured to store a process that is executable by the processor, the process when executed configured to:
select a range of client identifiers;
send, via a beam cone transmitted in a substantially downward direction towards a floor of an 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 an overhead mesh of access points in the area;
merge, by the apparatus, 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;
detect a collision between the best effort transmissions of the client devices; and

adjust the range of client identifiers to avoid future collisions between the best effort transmissions of the client devices.
