Cisco Unified Wireless Network Split-MAC Architecture

With the Cisco UWN split-MAC operation, the control and data messages are split. LWAPs communicate with the WLCs using control messages over the wired network. LWAPP or CAPWAP data messages are encapsulated and forwarded to and from wireless clients. The WLC manages multiple APs, providing configuration information and firmware updates as needed.

Access Point Responsibilities:

– Real-Time 802.11 MAC Functions
+ Beacon generation
+ Probe responses
+ Informs WLC of client probe requests
+ Power management and packet buffering
+ 802.11e/WMM scheduling and queuing
+ MAC layer data encryption and decryption
+ 802.11 control messages (ACK, RTS/CTS)
– Data encapsulation and de-capsulation via CAPWAP
– Fragmentation and re-assembly
– RF spectral analysis
– WLAN IDS signature analysis
