Figure 61: Example of Channel Usage in 2.4 and 5 GHz (Two Channels used if 40 MHz)
Try to determine which clients will be used and check the coverage using those clients. For example, a PDA or Wi‐Fi phone might not have the same range as a notebook or tablet.
Tip: Verify coverage using the worst performing clients that you intend to deploy.
If you require three spatial stream coverage for the fastest throughput or if you want the best BYOD experience, the AP 3600 and the AP 2600 with ClientLink 2.0 outperform the AP 3500. The AP 3600 can beamform to 802.11n clients, so it is important to understand the data requirements if you mix the AP 1260, 3500, and 3600 in the same areas.
While site surveys are generally recommended, if the design is done at half power and Cisco RRM is in place, a limited site survey may be adequate for smaller venues. In very challenging environments such as train connectivity, Gas & Oil verticals, large hospitals, and so forth, you can contract with the Cisco Advanced Services team to help or to perform your installation. Contact your Cisco account team for more information.
The AP 3600 was introduced in the 7.1.91 or higher code stream and is supported by the following: Cisco 2500, 7500, 5508, and WiSM2 Series Controllers, WCS 7.0.220 or higher, and NCS 1.1 or higher. The AP 1600 and the AP 2600 were introduced in the 7.4 release.
The rule of thumb coverage plan is: one AP per 5,000 square feet for data and one AP per 3,000 square feet for voice and location services.
Some clients (especially older ones) do not support the UNII‐2 extended client channels 100‐ 140; therefore, if you have older clients, you may want to disable them in the DCA channel list.
Note: The newer 802.11ac clients support these channels, and more clients are starting to support these channels all the time.
