This lets you immediately see each statistic in its proper context. For example,
an error rate of 50% is insignificant if Observer has only analyzed two
packets, but quite significant if thousands of packets have been analyzed.
The bar graphs to the right of the dial show current bandwidth utilization (U),
the average strength (S), and the average quality (Q) of the signal. These
meters also indicate (with watermark "floats") the minimum and maximum
values that Observer has seen since the last polling period.

Top Talkers (Three New tabs)

The Top Talkers statistical mode displays three tabs showing wireless data
when Observer is capturing packets via the wireless NIC: Wireless Types,
Wireless Speeds, and Wireless Latest These tabs are described in detail below.

Wireless Types

This display shows the type of each station sensed in the air: whether it is a
LAN station talking over the air to wireless stations, a wireless station, or an
AP. For stations, it shows which APs they are using. For APs, it displays the
Service Set Identifier (SSID) and whether WEP is enabled on that AP. It also
displays Control, Data and Management totals per station. As with other
tabular displays in Observer, right-click on the column headings to configure
the column view.
