Introduction to Wireless LAN Analysis
Other applications are session-based, such as Telnet, and may time out
(breaking the session) with the loss of only a few frames.
Because of these problems, it is paramount to maintain continuous RF
coverage through the areas of the facility where users need access to
wireless applications. Regular RF coverage analysis, as part of the
installation process of access points, and periodically measuring and
analyzing coverage throughout the life of the network will make
continuous RF coverage a reality. If RF coverage analysis is not part of
the regular routine, the wireless LAN will likely cause end-user
headaches on a regular basis.
Learn How Wireless LANs Operate
The analysis of wireless LANs leads to a much better understanding of
how the protocols and RF propagation work. After taking
measurements using protocol and RF analyzers and interpreting the
results, you gain a much richer understanding of wireless LANs. The
data and corresponding reports enable you to clearly see the frame
exchange sequences and statistics between nodes on a wireless LAN.
A more in-depth appreciation and understanding of how wireless LANs
function helps you better support them. When symptoms occur, you
are able identify the underlying problems much faster, and thus reduce
downtime and increase the availability of the system to users.
When Should You Apply Analysis?
Analysis applies to many aspects of the life of a wireless LAN. Be sure
to incorporate analysis into every phase, from design to operational
support.
System Design
You should perform analysis when designing the system in order to
determine whether the chosen wireless LAN technologies, architecture
and components will adequately support application and user
requirements. Design analysis is especially necessary when the
business requirements will likely stretch the limits of the wireless LAN.
