4.2.5.5 Continuous Noise Floor Display (AU only)
The Continuous Noise Floor Display option displays continuously updated
information regarding the average noise floor in the wireless link. It also displays
continuously updated information about the Signal Interference Ratio. Signal
Interference Ratio (SIR) is the average SNR for all pulses and physical errors
received by the unit. The average has the same formula used for calculation of
SNR per CPE.
Click the Esc key to abort the display.
4.2.5.6 Hidden ESSID Table (SU only)
An SU with Hidden ESSID Support enabled (for details see “ESSID Parameters” on
page 111) that maintains a list with AUs that rejected association requests from
the SU because of a wrong ESSID. An AU will be kept in this list until the Hidden
ESSID Timeout expires for it or if the list is full and another AU that is not in the
list rejects the SU because of wrong ESSID.
The Hidden ESSID Table displays for each AU included in the list its MAC Address
and Age (elapsed time in minutes since it was added to the table).
4.2.5.7 Per Modulation Level Counters
The Per Modulation Level Counters display statistics relating to wireless link
performance at different radio modulation levels. The Per Modulation Level
Counters menu includes the following options:
Display Counters: Select this option to display the current values of the Per
Modulation Level Counters.
Reset Counters: Select this option to reset the Per Modulation Level Counters.
The statistics show the number of frames accumulated in different categories
since the last reset.
For SUs, the Per Modulation Level Counters display the following information for
each modulation level supported by the unit:
SUCCESS: The total number of successfully transmitted unicasts at the
applicable modulation level.
FAILED: The total number of failures to successfully transmit unicast frame
during a HW Retry cycle at the applicable modulation level.
