Wireless Access Point
Viewing Status on the Wireless AP 119
At the bottom left of the frame, you may select whether to display only
2.4 GHz channels, 5 GHz channels, or both (the default is both). Note that
the data is an instantaneous snapshot — it is not an average or a
cumulative total.
Spectrum Analyzer Measurements
The spectrum analyzer displays the following information:
Packets/Sec: Total number of wireless packets per second on the channel,
both valid and errored packets.
Bytes/Sec: Total number of wireless bytes per second on the channel,
valid packets only.
802.11 Busy: Percentage of time that 802.11 activity is seen on the channel.
Other Busy: Percentage of time that the channel is unavailable due to
non-802.11 activity.
The total busy time (802.11 Busy plus Other Busy) will never total more
than 100%. The remaining time (100% minus total busy time) is quiet
time — the time that no activity was seen on the channel.
Signal to Noise: Average SNR (signal to noise ratio) seen on the channel,
calculated from the signal seen on valid 802.11 packets less the noise floor
level. A dash value “-“means no SNR data was available for the interval.
Noise Floor: Average noise floor reading seen on the channel (ambient
noise). A dash value “-“means no noise data was available for the
interval.
Error Rate: Percentage of the total number of wireless packets seen on the
channel that have CRC errors. The Error rate percentage may be high on
some channels since the monitor radio is set to receive at a very sensitive
level, enabling it to hear packets from devices at far distances.
Average RSSI: Average RSSI level seen on 802.11 packets received on the
channel. A dash value “-“means no RSSI data was available for the
interval.
Average Data Rate: Average data rate over time (per byte, not per packet)
seen on 802.11 packets received on the channel. A dash value “-“means
