The stunning success of 802.11 is based on
its development as "wireless Ethernet," which made it instantly
familiar to the large community of Ethernet LAN administrators. As 802.11
continues its ascent, though, its differences from Ethernet are becoming more
apparent. Many of these differences are due to the relative unfamiliarity of
many network administrators with the radio frequency physical layer.
While all network administrators must gain a basic understanding of the radio
link, a number of tools are beginning to incorporate critical radio analysis
functions to help them in this task. Wireless network analyzers have long been
an indispensable tool for network engineers in troubleshooting and protocol
analysis. Many analyzers have added some security functionality that allows them
to take on security audit functions as well. Products are now filling out the
security role and moving into radio management by taking advantage of the fact
that they are often used around trouble spots or to diagnose user complaints.

and why a wireless analyzer is a vital tool
for ensuring the security of wireless networks.
