Cisco Aironet Series 3700 Access Point

Radio Interfaces and Understanding Client Associations - AP 3600

As previously mentioned; the AP with module has three radio interfaces, “slots 0-2”, and shares the same
RF power characteristics and SSIDs. This permits both radios to function as a “virtual” or “blended”
radio, therefore; RRM controls both the integrated radio and the module radio.

Given there is no “greenfield” 802.11ac mode, RRM, Rogue AP detection, and SI (Spectrum
Intelligence) all continue to function normally.

Figure 77

Understanding RF Radio Interfaces

Because 802.11ac is fairly new, having a dedicated module handling the VHT (Very High Throughput)
requests makes it easy to see which clients are connected at 802.11ac rates and which 802.11ac clients
are actually connecting at 802.11n rates. This is accomplished by observing the SLOT ID.
