Wireless Site Survey
Scans selected wireless channels, displaying detailed activity on the WLAN by
channel.
Menu Path
Statistics->Wireless Site Survey (only available when a supported wireless card and
driver are installed.)
Purpose
The Wireless Site Survey displays activity by channels on your wireless network. Its
eight tabs show detailed statistical counts, letting you limit the display to Transmit
(TX) and Receive (RX) where appropriate.
Two things to note about the Site Survey:
• You must set the channels to scan in the Probe or Device Properties dialog,
802.11a/b Settings.
See “Wireless 802.11a/b Tab” on page 261.
• When Observer is scanning channels, the other modes (such as Top Talkers,
Access Point Statistics) will no longer be able to present complete view of the
network, as Observer’s data sample is limited to the current channel being
scanned. Therefore, you should only use the Site Survey by itself.
The tabs and the information on them is described in the following sections.
Note that some fields are hidden by default; to reconfigure the display,
right-click on the statistics column heading.
