Example of Channel Usage in 2.4 and 5 GHz (Two channels used if 40 MHz)
3.
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.
4.
While site surveys are generally recommended, if the design is done at half power and Cisco RRM 
is in place, sometimes a limited site survey (coverage check) is adequate for smaller venues. If this 
is a very challenging environment such as train connectivity, Gas and Oil verticals, large hospitals, 
and so on, Cisco has an Advanced Services team that can be contracted to help you get up to speed 
or perform your installation. See your Cisco account team for more information.
5.
The rule of thumb coverage plan is: 1 AP per 2500 square feet.
6.
Some clients (especially older ones) do not support the UNII-2 extended client channels 100-140. 
So, if you have a lot of older clients you may 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.
Questions and Answers
Q.
Which AP is best for Hospitality, dorm rooms, and smaller venues?
A.
The AP-702W.
Q.
Which AP is best for manufacturing and warehouse areas?
A.
Generally speaking the AP 3700e, 3600e, or 2700e would be the first choices because these external 
antenna models have the highest operating temperature range, -20 to 55C. The AP-1600 can also be 
used but it has a slightly lower operating temperature, -20 to 50C. If temperature is not a concern 
then the internal antenna “I” series 1600, 2600, and 3600 may be used.
