  23. Industry Value Chains • There are three inter-related ‘value chains’ involved in provision of mobile internet solutions to the user • Need to understand and selectively play based on where value is captured, who owns the customer relationship Terminals H/w Components Service delivery Devices S/w Components Service Providers Network Infrastructure Network Operators e-Commerce infra-structure Content & services Portals Pipe or portal? Walled gardens? Sticky gardens? Services

  25. Core Benefits Connected Electronic Organiser Mobile Feature Phone Dial/answer Contact SMS Contact Fax Contact Email Contact SyncML Messaging Internet Access

  26. i-Mode • i-Mode has “crossed the chasm” in Japan • 5 million subscribers now • 10 million forecast within 18 months of launch • Overtaken Nifty (Japan’s largest wired ISP) • Subscribers currently increasing by >100K per week • >3k i-Mode web sites increasing by 150 per week • Controlled by network operator - NTT DoCoMo • Only 9600 bps - speed is not the main benefit • Uses PDC-P - packet switched service always on • Based on HTML 3.0 with additional tags • No new language for content providers to learn • Only Japan, so roaming not an issue

  27. WID Design Issues

  28. Design trade-offs Data • Data vs. voice • Separate devices? • Separate networks? • Separate service contracts? • Performance vs. availability • Performance: functions, processing power, screen, keyboard • Availability: size, weight, battery life, instant on, responsiveness Nokia 9110 Palm VII RIM Blackberry Smartphone Mobile phone Phone Performance PC Notebook Series7 Series5 Revo Palm III Availability

  29. Form factors Phone IrDA orBluetooth • Keyboard vs. pen • Just pen, just keyboard or keyboard+pen • Pointing devices improve the UI experience • Keyboards make text input easier • 1-box vs. 2-box (or even 3-box) • IrDA 2-box • Bluetooth 2-box (or 3-box) • Flexibility vs. simplicity • Hold to ear vs. headset and hands free • Voice control? Handheld Computer 2-box Radio Bluetooth Handheld Computer Headset 3-box

  30. Application models • Thin client (fixed client) • WAP, Web (HTML), Citrix • Easiest to program, widest standard • Synchronisation • SyncML • Responsive off-line usage, best user experience, efficient use of wireless bandwidth • Client-server • Connected Java or C++ application • Best on-line user experience • Push • New model, SMS smart messaging • Asynchronous notifications 13

  31. WID Platform Positioning Rich user experience Citrix EPOC C++ HTML Java Webclipping Network dependent Off-line capable I-mode SMS WAP Basic user experience

  33. Technologies

  34. Technologies • Microbrowsers • SyncML • GSM -> GPRS -> EDGE -> UMTS • Bluetooth • Java • DAB • Speech recognition

  35. Microbrowsers • WAP • C-HTML • I-mode • Microsoft have their own cut down HTML • Palm’s Web clipping • “Full” HTML in a small screen • Psion (EPOC), Nokia 9110 (GEOS) • Symbian communicator class devices will have a full browser • XHTML is attractive • Multimode microbrowsers • E.g. HTML + WAP

  36. WAP • Functionally similar to Web • Very limited client capability assumed • Designed for small screens, limited OS, narrow bandwidth,high latency – “long thin pipe” • All mobile phones will have a WAP browser soon • WAP browser compatibility is biggest issue today • Some security problems at the gateway • WAP implementations will get better • WAP standard will evolve and get better • WAP essentially mandated by network operators • Several 100M WAP phones will drive WML content/services • Will not charm (user interface not good) • Really needs GPRS – which is really coming • WAP is a “must have” but it is not the full mobile internet answer • Attractive to content/application providers because of installed base

  37. Browser Platform Data Source XML Transcoding (Using e.g. XSL) n n n HTML Small screen HTML WML WML/HTTP WAP Gateway WMLBIN/WSP PC Web Browser WID Web Browser WAP Browser

  38. Repurposing Data Source HTML Repurposing Proxy PC Web Browser Small screen HTML WML WAP Gateway WID Web Browser WAP Browser

  40. SyncML • Industry initiative for an open synchronisation platform • Sponsored by Ericsson, IBM/Lotus, Motorola/Starfish, Nokia, Palm & Psion • Enduring need for local data despite improvements in wireless bandwidth and coverage • E.g. you don’t want to use WAP to get every contact number • Synchronised data includes contacts, calendar, todo’s, files, database records, application programs • Standard sync protocol that meets the need for interoperability between terminals and servers • Terminals: from phones to WID’s to PC’s • Services: Internet-based PIM, email, backup, installing applications • Psion producing EPOC client and corresponding services • See www.syncml.org

  41. Bluetooth • Low cost, low power short distance radio link • Data and Voice • 10m range but can be turned up to 100m • Uses globally available spectrum (2.4GHz) • Overwhelming industry support • Makes 2-box and 3-box more attractive • Also attractive for accessing LAN’s via network access points • More effort to ensure interoperability than IrDA • Integration cost target is $5 but this needs time and enormous volume • 2-3 years to reach sub $10 • See www.bluetooth.com 15

  42. Wireless broadband? Growth in Wireless Data Speeds • Speed will drive market growth • Speed will improve markedly • But this has been over-hyped • Real speed less than theoretical maxima • A few megabits per base station • Broadband is “Always On” connectivity model • No call set-up required • Instant Access • Better user experience • Enables new / richer applications 2,000 1,500 1,000 Megabits Per Second 500 0 GSM GPRS EDGE UMTS Today 2000 2001 2003

  43. GPRS • Packet switched data on GSM networks • IP connection to network operator’s intranet • Coverage starting 2nd half 2000 • Full domestic roll-out will take ~2 years, roaming support may take longer, numerous practical problems • Always connected more important than bps • Will transform WAP experience • GPRS data rates have been over hyped • Super hype 170kbps, hype 115kbps, reality 43kbps • Charging model still uncertain • One simple option is price per packet • E.g. NTT DoCoMo charges 0.3 Yen per 128-byte packet ($24 per MB or $1.35 per minute assuming $1=100Yen) 16

  46. Digital Audio Broadcasting • Digital Audio Broadcasting • Also called Digital Radio • Digital replacement of Analogue FM/AM • FM/AM transmissions will cease in 5-10 years • Eureka 147 • Pioneered by the BBC some 10 years ago • ETSI standard for transmission of DAB (1995) • Being adopted world-wide (except US & Japan) • Availability • BBC have been broadcasting since 1995 • UK Commercial stations launched November ’99 • In Europe, DAB transmissions are available to 150 million people

  47. World-wide Adoption
