Installation guide

Try to determine which clients are going to 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 3 spatial stream coverage for the fastest throughput, and/or you are looking for the best

BYOD experience, the Cisco Aironet 3600 Series Access Points with ClientLink 2.0 performs better

than the AP 3500. The AP 3600 can beamform to 802.11n clients, so it is important to understand the

data requirements if you are mixing Cisco Aironet 1260, 3500 and 3600 Series APs 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 (coverage check) can be adequate for smaller venues. If this is a

challenging environment such as train connectivity, Gas and Oil verticals, large hospitals, etc. Cisco

has an Advanced Services team that can be contracted to help you get up to speed or perform your

installation. Contact your Cisco account team for more information.

Cisco AP 3600 was introduced in the 7.1.91 or later code stream and is supported by the following:

Cisco 2500, 7500, 5508 and WiSM2 Series Controllers, and WCS 7.0.220 or later and NCS 1.1 or

later.

The rule of thumb coverage plan is: 1 AP per 5,000 square feet for data and 1 per 3,000 square feet

for voice and location services.

Some clients do not support the UNII−2 extended client channels 100−140. Therefore, if you have

lots of older clients you might want to disable them in the DCA channel list.

Note: More and more clients support these channels all the time, as will the newer 802.11ac clients.

A Quick Look at Some "Bad"Installations

The next two figures present examples of installations that are not recommended. It is difficult to provide

good Wi−Fi service with a "bad" installation. Figures 40 and 41 show an AP installation near metal and

clutter. Make sure to avoid metal and clutter.
