• Why a Unified Controller-based Architecture? All successful commercial mobility networks are based on concept of centralized control &
aggregation of the radio access network (RAN) using a radio network controller (RNC)Next-Gen 4G LTE wireless networks also support centralized RAN control (C-plane) and allowseparation from the data (U-plane)
• RNC Provides mobility networks with:Radio Resource Management (RRM) to maximize coverage and capacity through network-wideRF quality and interference-aware resource allocation
Controlled handoff Single security & inter-operability point between RANsSingle access control, SLA and policy-enforcement point

Wireless Access Controller (WAC)• Wireless Mobility Controller (WMC)
Fast and seamless handoff for L2 &L3 services (802.11r/k)Controls handoff between APs (intra/inter WMC)Uses RF parameters in mobile-assisted handoff
CleanAir & RRM provide industry-leading interference mitigationCapacity and coverage booster for all deploymentsLicensed spectrum ―experience in unlicensed band
LAN, MAN or WAN Connected (L2 or L3 transport)Not limited by size of L2 domain or transport technology
• WifiAccess Gateway (WAG)Per user (PCEF) and per VLAN/SSIDpolicyWiFi access control (e.g. EAP-SIM, WebAuth, etc)Inter-network mobility - Proxy Mobile IP (3G-Wi-Fi, inter-vendor)

• HotSpot (e.g. public access retail)Single facility co-located with access router (e.g. ISR) for charging & Internet offloadTypically a discontinuous coverage area (limited need for micro-mobility)C-plane only WMC centralized mgmt, provisioning, RRM, etc
• SMB (managed services)Dual SSID (for MSP) with bundled services (e.g. VPLS, IP-PBX, FMC, etc)Similar coverage as HotSpot and typically supported with C-plane only WMC
• Residential (MDU)Clusters of semi-contiguous coverage areasSimilar coverage as HotSpot and full or C-plane only WMC depending on mobility/capacity required

• Cisco’s controller -based Wi-Fi architecture provides real-time mobility seamless roaming covering majority of the user-experience within the Wi
cluster • Mobile IP provides IP service continuity using client-based (CMIP/iWLA
network-based methods (PMIP). This addresses non-SP provided WiFi (eresidential) and inter-network (e.g. Wi-Fi metro -> 3G WAN)
• Seamless Wi-Fi roaming between operators (e.g. 3G offload) is provided widely available and emerging authentication techniques and complemenclient-based methods (e.g. iWLAN) dependent on Wi-Fi roaming
