  • www.tsiconnections.com Relentless Ingenuity Public WLAN Roaming
  • WLAN Roaming:
    • Public WLANs as Compliments to 3G Services
    • The WLAN Value Chain
    • Business Model Considerations
    • WLAN Roaming Summary and Challenges
  • Network Comparisons
    • 3G networks
      • Provide wide-area always-on coverage
      • Modest-data-rate applications
      • Data and voice share same spectrum which inhibits flat-rate data pricing
    • WLANs
      • Yield the low network cost per kb for data-intensive applications
      • Support flat-rate or time-based pricing for data services
  • Network Comparisons ROI declines across service profiles as colors change from green to red Service Profile SMS WAP Voice Email w/o Attach. Mobile Professional Mobile Service Worker Full Desktop Equivalent Network Cost $ $$$ 2G 3G WLAN
  • 3G and WLANs: Complimentary Technologies
    • Market studies indicate that user demand for high-speed Internet/Intranet applications is greatest in quasi-stationary environments
    • Data roaming combines 2.5/3G technologies for wide-area, low-data-rate coverage with WLAN access for localized high-data-rate coverage
    • Consideration of the WLAN value chain identifies challenges to sustainable business models for integrated wireless data services
  • Value Chain Participants: Cellular Roaming
    • Wide-area cellular networks don’t require property access agreements
    • Mature business models, well developed data exchange processes
    • Large numbers of transactions
    • Little need for aggregator services
    Visited Operator Visited Operator Visited Operator • • • Clearinghouse Home Operator
  • Value Chain Participants: WLAN Roaming
    • WLAN business models are immature and evolving
      • many small operators, few transactions compared to cellular voice services
    • Venues are strong participants in WLAN value chain
      • many local property agreements required for WLAN coverage
      • large venues may directly manage neutral host access
      • venue revenue share complicates pricing strategies
    • WISPs and aggregators may offer branded service or unbranded wholesale access
    Venue Venue Venue • • • Local WISP (Optional) Clearinghouse or Aggregator (optional) Home Operator
  • Entities Participating Data Roaming Value Chain
    • WISP - provider of public wireless Internet services via operation of venue access points.
      • example: Wayport, Spotnik, ANS, Cometa, …
    • Aggregator – provider of retail WLAN services through marketing and resale of WLAN access from multiple WISPs.
      • example: Boingo, Airpath
    • Broker (or Aggregating Broker) – provider of wholesale access to multiple WISPs via multilateral roaming and resale agreements.
      • example: iPass, GRIC
    • Clearinghouse – provider of AAA information flow and other services (e.g. billing mediation, financial settlement) between two or more service providers.
      • example: TSI, Verisign/Illuminet
    • Mobile Operator - operators of mobile networks with data services.
      • example: Verizon, SK Telecom, Telecom New Zealand…
  • Business Model Considerations
    • The Neutral Host
      • Airports and premier venues are leaning towards the “Neutral Host” business model
        • venue owns the WLAN network and offers access to all users via roaming, credit card, and/or prepaid access
        • venue contracts with neutral host manager for operations and marketing support services
        • roaming AAA functions and home-network billing is supported via relationship(s) with clearinghouse
        • maximizes revenue generation
        • for the venue owner
        • One-way Roaming
  • Business Model Considerations
    • Aggregators
      • provide access to multiple-WISP hot spots
        • revenue model based on wholesale-retail markup
        • provides centralized AAA functions
        • client software provides uniform user experience
        • aggregator model appeals most to small WISPs or individual hot spots
        • Roaming agreements could be bi-lateral
    • Clearinghouses
      • Provides AAA functions for inter-WISP and cross-bearer roaming
        • Revenue based on transaction fees for AAA, billing mediation, settlement
        • Do not negotiate wholesale access rates
        • Can support wide range of billing options:
        • AAA function supports proxy authentication to home database
        • manage complexities of multiple roaming agreements
                   
  • Other Considerations
    • Customer Experience
      • Smart Client
        • Flexible
      • Range of alternative access available
      • Customer Service
        • Inquiries
        • Problem Resolution
    • Management of Roaming Agreements
      • Greater number of players
        • Wireless Operators
        • WISPs
        • Aggregators
