Site Name indicates the name of the SM. You can assign or
change this name on the Configuration web page of the
SM. This information is also set into the sysName SNMP
MIB-II object and can be polled by an SNMP management
server.
Uplink Statistics -
Power Level: Signal
Strength Ratio
This field represents the combined received power level at the AP/BHM
as well as the ratio of horizontal path signal strength to vertical path
signal strength.
Uplink Statistics –
Fragments
Modulation
This field represents the percentage of fragments received at each
modulation state, per path (polarization).
Uplink Statistics –
Signal to Noise Ratio
This field represents the signal to noise ratio for the uplink (displayed
when parameter Signal to Noise Ratio Calculation during Link Test is
enabled) expressed for both the horizontal and vertical channels.
Uplink Statistics –
Link Test Efficiency
This field displays the efficiency of the radio link, expressed as a
percentage, for the radio uplink.
Downlink Statistics –
Beacon % Received
Curr/Min/Max/Avg
This field displays a count of beacons received by the SM in percentage.
This value must be between 99-100%. If it is lower than 99%, it indicates
a problematic link. This statistic is updated every 16 seconds.
Downlink Statistics –
Power Level: Signal
Strength Ratio
This field represents the received power level at the SM/BHS as well as
the ratio of horizontal path signal strength to vertical path signal
strength at the SM/BHS.
Downlink Statistics –
Signal to Noise Ratio
This field represents the signal to noise ratio for the downlink (displayed
when parameter Signal to Noise Ratio Calculation during Link Test is
enabled) expressed for both the horizontal and vertical channels.
Downlink Statistics –
Link Test Efficiency
This field displays the efficiency of the radio link, expressed as a
percentage, for the radio downlink.
Downlink Statistics –
SU-MIMO Rate
The SU-MIMO rate applies to all AP platforms.
For 450m, this field indicates the rate being used for symbols where this
particular VC is not being MU-MIMO grouped with other SM’s.
For 450 and 450i platforms, there is no grouping and this field indicates
the modulation rate for all symbols.
Downlink Statistics –
MU-MIMO Rate
The MU-MIMO rate applies only to the 450m AP. This field indicates the
modulation rate used for symbols where this particular low priority VC is
MU-MIMO scheduled by grouping it in the same slot with other low
priority VC’s.
