Yes. All 3 radios will be active 

The 2.4 GHz radio continues to support legacy b/g clients as well as n clients. The two 5 GHz radios 
(integrated + module) will work in tandem so they are not competing with each other but working 
in concert to support the same channels. For instance: 

The 802.11ac module adopts an 80 MHz wide channel on 100-104-108-112 

The 802.11a/n integrated radio operates on Channels 100-104 and a 40 MHz wide channel for 
802.11n clients, and 802.11a clients communicate with the integrated radio via Channel 100 and 
a 20 MHz wide channel 

The AP3600 with the new 802.11ac module installed, will provide concurrent support for both the 
2.4 and 5 GHz bands and support for 802.11 a, b, g, n and new 802.11ac clients. 

On the 5 GHz side, it is possible to have a 20 MHz wide 11ac channel and a 40 MHz wide 11n channel, 
the only requirement is that the primary channel should be the same for both slots and is determined by 
the primary channel setting on the integrated 11n radio. 

Can both 5 GHz radios (integrated and 802.11ac module) be on different channels? 

No. The two 5 GHz radios will work together on the same channels, which allows the 5 GHz radios 
to not compete with each other and allows us to maximize the number of clients supported per radio. 
The primary (integrated .11n radio) will take the lead with the module radio “extending” or bonding 
from the primary channel set on the integrated radio.

Any other thoughts when installing wireless Access Points?

When doing wireless installations, keep the following guidelines in mind:

It is all about placing the AP as reasonably close to the actual users as possible, 

Making sure you have coverage, (to a known requirement) and compensating for nulls or dead 
spots regardless of what product you choose to deploy - This is called a site survey.

Installations should be done based on lessons learned from the site survey – the better the survey 
the less likely connectivity problems will occur.  

Cisco has an advanced services team that can perform WLAN surveys or help with the wireless 
design if a partner is not available or able to do same.

When possible, use Cisco brand antennas listed in this paper (with the orange band) 

Use common sense - don’t mount antennas against metal objects. Similar to a light bulb, 
antennas work best when there are no obstructions in the path.

AP 1600, 2600 and 3600 are not weatherproof and has an IP rating of 40.
