Step 2: Analyzing Requirements

After gathering information, the next step is to analyze the requirements for the WLAN. Some of the information you collect may map directly to requirements. For example, the answer to a question regarding use of legacy client radios (802.11a, 802.11b, or 802.11g) might result in an understanding that the WLAN needs to support use of client devices equipped with 802.11b/g radios. As a result, the requirements you analyze/define would indicate a need for supporting legacy devices.

In most cases, however, answers to your questions will not provide all requirements. You are often left with filling in some of the “holes” by specifying requirements that make the most sense based on the known requirements. This is where you need to do some thinking and pull from experience. If you find yourself in this position, focus on choosing requirements that best enable the WLAN to provide expected benefits.
