Introduction to Wireless LAN Analysis
analyzes his powerful post-up moves. Analysis is meant to continually
improve performance, and this methodology holds true for today’s
wireless LANs. Analyzing your wireless LAN and improving its
performance increases return on investment because of higher up-time
and ability to effectively support applications.
Maximize Performance
With a growing use of higher end applications over wireless LANs, it is
becoming crucial to maximize performance. Users want to stream
video from websites and send large email attachments. End users
typically do not consider that the wireless LAN does not have the speed
and capacity of the wired LAN they are accustomed to using. This
misunderstanding puts high expectations and a big strain on the
wireless network.
RF interference may also crop up from time-to-time, which increases
overhead on the network and reduces throughput. This somewhat silent
issue causes applications to run slowly or even to fail altogether.
Unfortunately, most companies take a reactive approach, waiting until
users complain before investigating what might be causing the
problem. In order to realize the ROI of a wireless LAN, it is imperative
to optimize it using a more proactive approach. Wireless protocol
analyzers allow you to take this proactive approach.
Because of the large number of wireless-enabled laptops and PDAs,
companies are finding that more users than expected are utilizing the
wireless LAN. Once it is known that a wireless LAN exists, people
think of new applications as well. In addition, hotspot operators, such
as airports and hotels, are striving to share their wireless LANs for both
public and private applications. As a result, there are many more users
active on the wireless LAN in any give area.
The increase in utilization of wireless LANs and varying presence of
RF interference is demanding thorough performance analysis to ensure
that all users can continually make use of their applications without
significant delays and frustrations. This performance analysis involves
carefully designing the wireless LAN and testing actual capacity after
installing the network. Also, regular performance analysis is necessary
to ensure the network keeps up with demands as the number of users
