  1. Wireless Service Providers & ASPs: Partnering for Mobile Internet Apps Vish Nandlall Chief Architect, Carrier Networks vnandlal@nortel.com

  2. Agenda • Why ASPs should partner with wireless service providers • Implications of wireless service provider trends for ASPs • Conclusions

  3. Agenda • Why ASPs should partner with wireless service providers • Issues with Mobile Internet’s market traction being resolved • Wireless service providers control key assets to enable apps • E.g., Best-Effort VoIP May Not Be Good Enough • Implications of wireless service provider trends for ASPs • Conclusions

  4. Low Bandwidth Relative to Fixed Internet UMTS WiMAX 802.16e EV- DO Rev C LTE Mobile Internet Cellular Mobile Wireless BB HSPA EV-DO / DOrA Voice & Messaging WiFi 802.11 n Local Area • Mobile Internet’s historically low • bandwidth  • Content limitations • Consumer impatience • Mobile, wireless broadband (BB) • deployments will eliminate this issue! 802.11 a/b/g WiMAX 802.16d VDSL / FTTH Fixed Any App over Broadband Increasing bandwidth 2007 Rollout 2008 & beyond Existing

  5. Unfriendly Handset Ergonomics • Unfriendly handset MMI  • User difficulty in obtaining • & viewing content • Handset vendors improving • iPhone set a new benchmark

  6. No Mobile Content Development Guidelines • Lack of guidelines  • Deters content development • Hinders usability of content • W3C’s Mobile Web Initiative (MWI): • Best practices & mobile device descriptions • .mobi top level domain for MWI-based content dotMobi Investors W3C MWI Sponsors

  7. Mobile Content Market Fragmentation • Fragmentation of market across: • Device types • Access network types • Operators • Limits market scope of developed • content  • Reduces incentive for content • development • Mitigating factors: • Access distinctions diminish with • wireless BB • 3 device types will dominate 2010 TechNewsWorld, 4/2006

  8. Walled Gardens Walled gardens = Limited access to Internet  Reduces user’s bang for the buck “Sprint sees ‘open’ model for WiMax” (InfoWorld, 1/2007) The walls are falling!

  9. “Vodafone, Yahoo Extend Partnership” for IM LightReading, 2/2007 “Alltel Extends Mobile Content Delivery Contract” cellular-news, 1/2007 Operator’s Revenue-Sharing Models “YouTube, Verizon deal is official” GigaOM, 11/2006 “X-Series from 3 Puts Internet on Your Mobile” Partnerships with Orb, Sling Media, Google, Microsoft, Google Mobile Marketing Magazine, 11/2006 • Historical models reduced incentive for content development • Growing # of operator partnerships indicate mutually agreeable terms

  10. Fixed Internet Content Hasn’t Met Mobile Users’ Needs • Online behavior of mobile & • fixed Internet users differs. • Situational, mobile-relevant • content emerging: • Timely • Location-relevant • Actionable Navigational & mapping services Breaking news Podcasts, video webcasts Live sportscast

  11. Mobile Internet Subscription Pricing Too High • Price has reduced end-user demand  • Reduces market for content developers • Prices likely to fall due to… • Market analysts recommending small • premium above DSL access tariffs • Competition from alternative wireless • access (e.g., WiFi, WiMAX) • Service providers re-examining pricing when • VoIP deployed over wireless BB Internet price Subscriber Usage

  12. Agenda • Why ASPs should partner with wireless service providers • Issues with Mobile Internet’s market traction being resolved • Wireless service providers control key assets to enable apps • E.g., Best-Effort VoIP May Not Be Good Enough • Implications of wireless service provider trends for ASPs • Conclusions

  13. Wireless Service Providers Control Key Assets to Enable Apps

  14. E.g., Best-Effort (BE) VoIP May Not Be Good Enough • Voice KPIs: • Voice quality • Call setup delay (i.e., post-dial delay) • Wireless channel characteristics: • Shared  BE traffic latency increases beyond a threshold of sector loading  policy-controlled QoS • Relatively slow  over-the-air (OTA) propagation can consume major portion of delay budget  access network-controlled header compression + efficient voice encoding with VoIP packet alignment with L2 frame sizes • Lossy  frame loss impacts voice quality & call-setup delay  UDP transport for SIP + limited SIP PRACKs + loss-resilient codec • User mobility may result in handoff to different channel, & can result in movement to different point of attachment in operator’s intranet  policy-controlled real-time enhancements to minimize break time • Mobile devices optimized around use of wireless-specific, IPR-encumbered codecs, & use of other codecs may perceptibly impact other apps Only wireless service provider can consistently deliver “quality” voice

  15. Agenda • Why ASPs should partner with wireless service providers • Implications of wireless service provider trends for ASPs • Conclusions
