  26. 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. 27. WID Design Issues
  28. 28. Design trade-offs • Data vs. voice Data – Separate devices? Palm VII Nokia 9110 – Separate networks? RIM Blackberry – Separate service Smartphone contracts? Mobile phone • Performance vs. availability Phone – Performance: functions, Performance processing power, PC Notebook screen, keyboard – Availability: size, Series7 weight, battery life, Series5 instant on, Revo responsiveness Palm III Availability
  29. 29. Form factors Phone •Keyboard vs. pen IrDA or – Just pen, just keyboard or Bluetooth keyboard+pen – Pointing devices improve the UI Handheld experience Computer – Keyboards make text input easier 2-box •1-box vs. 2-box (or even 3-box) – IrDA 2-box Radio – Bluetooth 2-box (or 3-box) – Flexibility vs. simplicity Bluetooth – Hold to ear vs. headset and hands free Handheld •Voice control? Headset Computer 3-box
  30. 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

  34. 34. Technologies •Microbrowsers •SyncML •GSM -> GPRS -> EDGE -> UMTS •Bluetooth •Java •DAB •Speech recognition
  35. 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. 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

  40. 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. 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. 42. Wireless broadband? Growth in Wireless Data Speeds • Speed will drive market growth 2,000 – Speed will improve markedly – But this has been over- Megabits Per Second 1,500 hyped – Real speed less than 1,000 theoretical maxima – A few megabits per base station 500 • Broadband is “Always On” connectivity model 0 – No call set-up required GSM GPRS EDGE UMTS – Instant Access – Better user experience Today 2000 2001 2003 – Enables new / richer applications
  43. 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. 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. 47. World-wide Adoption
  48. 48. User Benefits of Digital Radio •Near-CD Quality Sound – MPEG1, Layer II : more like Minidisk (5:1) than MP3 (12:1) •Robust reception – Interference-free, even when mobile •Single Frequency Network – No re-tuning required when travelling •More listening choice – Several new Digital-only stations •Data Services – PAD - Artist and Track names with Audio stream – Packet Mode - Broadcast Web Sites
  49. 49. DAB Multiplex • To make efficient use of the frequency spectrum, several audio and data services are brought together into one Multiplexed bit-stream Audio Service 1 1.5 Mbps Audio Service 2 Audio S1 Audio S2 Audio S3 Data S1 192 Kbps 192 Kbps 96 Kbps 64 Kbps Audio Service 3 Examples of data rates: Stereo Music Service 128-192 Kbps Mono Music Service 96 Kbps Mono Speech Service 64 Kbps Data Data Service (multiples of 8 Kbps) 64 Kbps Service 1 Note: The sub-channels can be dynamically reconfigured by the Multiplexer without interrupting the audio flow
  50. 50. Broadcast Websites • DAB is true „push‟ technology – Can provide a flow of real-time information from Internet content · BBC‟s Vision Radio is created from BBC On-Line site · News, Weather, Travel, Sport & Electronic Program Guides · Can be „synchronised‟ with Audio transmission – Commercial stations looking at E-commerce options – New Advertising opportunities • Carousel transmission – Like Teletext, data has to be transmitted in a Carousel · Data must be repeated as user can switch on at any time · Receiver builds a copy of the Website in memory (1-2MB) · Can request data with a back channel via PSTN or GSM Modem
  51. 51. WaveFinder – A Smart Antenna for the PC • PC based DAB receiver • Uses PC CPU, display and sound system – Connects via USB – Links Radio to the Web (25% of surfers listen to the radio) • High quality audio source – CD Quality unlike FM or „streamed‟ radio – Record in secure MP3 format on hard-disk or CD-R – For MP3 users, it is the first „free-to-air‟ source of MP3 music • Receive new data services – PAD and Broadcast Web Sites • PC provides back-channel • Fixed today, mobile tomorrow, DAB with GPRS back-channel • See www.wavefinder.com
  52. 52. Java NT, Unix, Linux, Solaris, MVS, AS400, VMS, legacy Server Problem for Desktop Windows Java to solve Devices EPOC, CE, PalmOS, Linux, JavaOS, OS/9, Proprietary
  53. 53. Java 2 Java2 Platforms J2EE J2SE J2ME Servers Desktop PC Devices Configurations CDC CLDC Profiles Foundation Profile MID Profile CDC = Connected Device Configuration CLDC = Connected Limited Device Configuration (KVM) MID = Mobile Information Device
  54. 54. Java on WID’s • MExE (ETSI GSM standard) – Mobile Station Application Execution Environment – MExE classmark 1 is WAP – MExE classmark 2 is WAP + Java • Symbian supports Java – JAE 1.1.4 on e.g. Psion NetBook – PersonalJava and JavaPhone on new DFRDs – J2ME profile/configuration to be decided thereafter · UI library is an issue (AWT unsuitable for some devices) – All EPOC devices will ultimately ship with Java • Applications, Applets, IBM‟s DirectDOM • Highly likely that standard Java platforms will be defined in the WID space
  55. 55. Speech Recognition •Limited vocabulary recognition is comfortably achievable •Speech dictation is borderline on next generation hardware platforms – E.g. 200MHz ARM, 64Mb memory •Speech UI‟s need to be worked out •WID form factor could be more ergonomically viable than a PC – More natural to hold to mouth – No large keyboard to compete with •PC dictation took off when 230 MHz PC‟s arrived •It‟s more a question of when rather than if
  56. 56. Summary • Many kinds of devices will access the internet – not just PC‟s – Wireless information devices will challenge the PC as the dominant internet access device • Mobile internet isn‟t just WAP – WAP will probably be the main driver over the next 1-2 years • Psion believes in a richer mobile internet experience than is possible with just WAP – or even any browser – Gap between wireless and wired bandwidth will increase and devices need a significant off-line capability – SyncML is an important mobile internet standard • Future is unpredictable and exciting – Numerous potentially disruptive technologies – Many competing form factors and platforms – Complex industry value networks which have yet to “lock” · Network operators, content providers, device manufacturers
