General - Profile Threshold for Traps
●
Adjust these for expected levels in the high-density coverage zone. It will make the traps and alerts
meaningful
Wireless=>802.11a/802.11b=>High Throughput (802.11n)
●
Should be enabled for both bands, with all MCS rates supported
Wireless=>Media Stream
●
Enable if supporting video streaming applications

For all of the above commands, it is strongly suggested that WCS and the AP and Controller Templates be used
to make changes and assignments. Using the AP groups feature is also highly recommended for organizing APs
by coverage zone and WLAN SSID configuration.
Conclusion
The performance of a high-density WLAN within a higher education environment is highly dependent on how well
the network requirements are understood before the network is deployed. A good understanding of these
concepts will enable the designer to modify the design to accommodate the unforeseen.
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.
