activePollTimeout and have not timed out on disassociationTime. Therefore payload counts
for
inactive EUMs indicate transitions from inactive to active.
NOTE: Broadcast traffic is carried with random access polls. Therefore,
forward traffic (CCU-to-EUM) in the broadcast row is broadcast
traffic, while reverse traffic is random access traffic. The reverse
packet rate should be less than 15% of the total poll rate for the
broadcast traffic, since random access attempts can collide.
Assuming uncorrelated arrivals, this should ensure that 99.7% of
random access attempts succeed (in four retries or less).
