It is important to have alternate options available, based on changing factors, and to remain flexible in approach as new
requirements and challenges are presented. For example, in most venues, aesthetics will be of paramount importance, and
anticipating a design response to an aesthetic critique in advance is useful. Understanding the performance differences between
an optimal solution and the less intrusive (or more aesthetically acceptable, with hidden APs) solution will leave the designer
prepared to have that discussion and to re-set expectations if necessary.

This paper has presented several design areas as concepts. Recommended values have been offered as examples, based
on experience with past solutions. The recommended values should be treated as a starting point and will provide a robust
performance window. Performance may vary based on conditions that are beyond the designer’s control, but understanding
these concepts and controls will allow the designer to design and communicate a realistic expectation of performance.

Appendix A: 5 GHz Channels Available Worldwide by Regulatory Domain
These are channels available by the Cisco regulatory domain worldwide to date. Note the change in status for channels 120 to
132 for the –A region. Interference with terminal Doppler Weather Radar caused a change in regulations in October 2009. APs
introduced before October 2009 will have these channels available. APs introduced after this date will not.
