The proliferation of mobile data devices (e.g. iPhone) and especially growth in mobile video (e.g. iPad) has motivated mobile operators and WiFi network operators (SP, SMB, Enterprise, etc) to collaborate in providing cost effective capacity relief of their 3G networks using WiFi. In this presentation, we will examine the drivers, contrast complimentary technologies (e.g. FEMTO, LTE) and identify key architectural elements that enable this key market transition. Following that, we will present Cisco's SP-WiFi solution, core values and related products in support of outdoor and indoor deployment.

  • Welcome to this year’s Networkers event! I’d like to call out a few house-keeping items for this year’s conference.If you haven’t already, download the Cisco Mobile Events app at bit.ly/cnsfapp. The app can be used on all types of Smart-phones and android devices.You have an opportunity to earn points, win prizes, view program highlights, link to peers, Cisco experts, and partners. When you click on ‘Check-In’ for the Networkers event, you automatically earn a ‘Canada’ badge! Also, if you are engaged in Social Media, join the Networkers 2011 conversation through Twitter, Facebook, and YouTube. Use hash-tag CNSF2011 to be part of the discussion.
  • I want to start with a brief overview of the market before going into the details of the SP Wi-Fi solution
  • Mobile telephone networks have seen one of the worlds fastest adoption rates in history, with 5 billion subscribers (connections) globally, this equals 70% of all men, women and children on the planet own or use a mobile phone.Many of these users don’t own a computer – their only connection to the Internet is on a smartphone-type deviceSubscribers who do own a computer expect to access the same services when mobile as they do when seatedThe result is skyrocketing rates of data consumption over mobile networks (it will grow by 39 times between 2009 and 2014)About 50% of all mobile data use in 2010 was video, which will rise to 66% of all mobile data by 2014
  • EAP-based authentication with secure (encrypted) access802.1X/EAP-TTLS/TLS for NOMADIC device roaming (i.e. CableLabs standard) and EAP-SIM for MOBILE device roaming (e.g. Wi-Fi-3G offload) Supported in virtually all Wi-Fi clients incl. embedded (e.g. iPhone) and OS-basedUniversal, secure & seamless HotSpot2.0 methods for NOMADIC and MOBILE devices allow operator access to larger partner and device ecosystem [roadmap] WebAuth authentication with open (unencrypted) accessWeb portal-based authentication with RADIUS and ISG-based access controlSeamless or “touch-free” methods (i.e. WISPr v1) supported by most MOBILE devices Multiple logical network providers per physical WLANMultiple SSIDs & associated VLAN (e.g. public, business, guest access)Pre-cursor to universal realm-based network discovery (802.11u) & service advertising (MSAP) in HotSpot 2.0Enforceable roaming across operatorsAuthentication with access or mobile operator (AAA proxy) as neededEnables end-to-end client-based (iWLAN) connectivity
  • ClearAir is a system-wide feature that uses silicon-level intelligence to automatically mitigate the impact of wireless interference, optimize network performance and reduce troubleshooting costsWith CleanAir, the system can detect and classify, locate, and mitigate interference. CleanAir allows operators to aggregate across APs to show impact on the system rather than individual devices only.
  • In the beginning, we had graphic rich smart devices – smartphones, PDAs, MIDs - with on-board high-speed communication technology but few networks to support there ravenous appetite for data.In SP-WiFi Phase 1, we introduces a variety of ruggedized high-performance outdoor, metro and indoor 802.11n access points that provided the foundation of high-speed unlicensed access (click). Coupled with RF and mobility optimizing controllers and per venue & regional access gateways, chargeable and metered Internet service is enabled to mobile and nomadic devices (click). Internet access as well as as management of user profiles, Web-based login & secure E2E authentication for the WiFi users is then provided by the WiFi core (click).
  • As WiFi grew in adoption and especially as a viable 3G/4G offload, there was a need to beef up both the air-interface & backhaul capacity – hence the introduction of 802.11n on our entire portfolio, CleanAir on our premium APs and DOCSIS3 on our outdoor APs. Equally as important, Cisco’s NextGenHotSpot or HotSpot 2.0 is being driven by Cisco as a technology to promote secure and seamless roaming. As 3G and “4G” technology evolves to offer higher-speed data access, interconnecting the new mobile core with the existing WiFi access networks becomes the key challenge. For WiFi networks untrustedby the mobile core operator, users may login via an “open” or Web-based network via the WiFi core (click) and the mobile initiates a secure iWLAN tunnel (IPsec and/or DSMIPv6) tp the PDG. (click) The PGW (click) and mobile authenticate using SIM credentials and connects to the service networks such as the Internet with PCEF-based policy enforcement.In a mobile operator or partner owned WiFi access scenario, the user typically seamlessly logs in via EAP-SIM/AKA and connects to the core via trusted S2a or PMIPv6 interfaces to the PGW.

    • 20. Unified Architecture
      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 allow separation from the data (U-plane)
      RNC Provides mobility networks with:
      Radio Resource Management (RRM) to maximize coverage and capacity through network-wide RF quality and interference-aware resource allocation
      Controlled handoff
      Single security & inter-operability point between RANs
      Single access control, SLA and policy-enforcement point
    • 21. Cisco Wi-Fi “RNC” Architecture 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 mitigation
      Capacity and coverage booster for all deployments
      Licensed spectrum “experience” in unlicensed band
      LAN, MAN or WAN Connected (L2 or L3 transport)
      Not limited by size of L2 domain or transport technology
      Wifi Access Gateway (WAG)
      Per user (PCEF) and per VLAN/SSIDpolicy

      Contiguous coverage area served by full Unified WMC  micro-mobility/handoff anchor
      WMC co-located with access gateway (WAG) for charging & Internet offload
      HotSpot (e.g. public access retail)
      Single facility co-located with access router (e.g. ISR) for charging & Internet offload
      Typically 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 areas
      Similar coverage as HotSpot and full or C-plane only WMC depending on mobility/capacity required

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