Defers This number counts the
number of times an
attempted transmission
was deferred due to the
medium being busy.
This is helpful in
determining if an
environment is very busy.
Defers are common in busy
WiFi environments
Tout This is an indicator of Tx
packet timeout
Timeouts are not common.
The Packet could not find a
time slot to transmit.
Retries
This counts the number of
transmission retries that
have occurred over the
last one second.
This is primarily due to the
lack of acknowledgements
from the partner device.
On the transmit side, note
that the general packet flow
for error is as follows:
Defer
Retry
Timeout
ShPre This counts the number of
Short Preamble Detection
Errors
These are very common in
high throughput conditions
LgPre This counts the number of
Long Preamble Detection
errors
The wireless received a
signal which passed the
short preamble, but failed
the more complex long
preamble. These are less
common than short
preamble errors.
Rate This is a legacy
measurement for rate and
is not currently used
