4.2.6.2.14 Noise Immunity Control
The Adaptive Noise Immunity (ANI) mechanism, active by default, is designed to
reduce the wireless physical layer errors and by that enhance the processing
power of the unit, delivering higher packet processing efficiency.
This ANI mechanism is triggered by the rate of detected Physical Errors and it is
modifying different thresholds affecting the immunity to specific interference
types.
Due to the high processing power of the AU, enabling it to process a relatively
large number of packets per second, the ANI mechanism (triggered by the number
of received error packets) may not function properly in certain scenarios, resulting
in link performances that are far below the expectations. The option of manually
controlling the various parameters used by the ANI mechanism enables to achieve
optimal performance in certain deployments where the automatic ANI mechanism
may not function properly.
It is strongly recommended to consult with Alvarion experts before switching to
manual mode and modifying any of the parameters.
Try switching to Manual mode if overall throughput is too low or if SUs are lost
although communication conditions are sufficient for good connectivity.
In many deployments the transition to Manual mode is sufficient. If not, you may
try changing the Noise Immunity Level and/or Spur Immunity Level parameters.
The target is to reduce the amount of Phy Error rate reported by the unit (see
Total Rx events on page 61). To ensure that sensitivity is not reduced too much
and SUs are not lost, verify that the Age (see Display Association Info on page 64)
of all SUs is below 20 seconds.
Do not activate the OFDM Weak Signal parameter if the SNR is below 26 dB
without fading margin. Under normal conditions, the OFDM Weak Signal should
never be activated in the AU, since the SNR of all SUs will be below 36 dB when
ATPC is enabled.
The Noise Immunity Control submenu includes the following options:
