Mu Association Process - Symbol Spectrum24 AP-3020 Reference Manual

interference exists on a given frequency, it affects the radio network for only a
short time on that specific frequency. Although APs can share the same
hopping sequence, they usually do not synchronize in time. Rarely do they
simultaneously arrive at the same frequency, referred to as contention.
Interfering signals can reduce overall throughput at some frequencies. This
reduces the probability and impact of overlapping frequencies or collisions.
Although devices can hop to the same frequency, they eventually hop to
different frequencies after the hop time.
With Spectrum24, each AP on the local network negotiates a different
hopping sequence at start-up. This allows APs to provide frequency
separation and evenly divide the frequency spectrum among the units.

MU Association Process

APs recognize MUs through an association method. The AP keeps a list of
MUs it services. MUs associate with the AP based on the following conditions:
