The size and complexity of your network are important considerations, but they're not the only ones. You should also consider the knowledge level of the person who will use the analyzer, as well as the amount of time he or she plans to use the device. The Basics You must make some basic choices about how you'll use your network analyzer. If you have a single segment network, then a desktop analyzer is probably fine, but you'll want a portable analyzer if you have a number of segments separated by bridges or routers. For large campuses, you'll be even more concerned about portability.
Some analyzers are barely luggable, while others are easily carried about.
In fact, some of the best UIs are found on software-based analyzers. Some larger anal yzers still have very cryptic UIs that are intended only for the people who developed the UI in the first place. More likely, however, is that the UI on some systems may be more intuitive and possibly less powerful than other interfaces. If you're not going to use the box daily, make certain that the UI is one you can use without having to spend too much time learning it. A few systems are devised so that they can be controlled remotely.
