23 Industry Value Chains Pipe or portal? Walled gardens? Sticky gardens?
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 Network Infrastructure Network Operators Service Providers e-Commerce infra-structure Content & services Portals Pipe or portal? Walled gardens? Sticky gardens? Services

24 WID-addressed Mobile Needs
Personal Organisation Voice Communication Messaging ( , SMS, fax) Information Access Mobile Enterprise Computing Mobile eCommerce Entertainment Handheld computer Mobile phone Voice - today's killer app! Messaging - SMS, , instant messaging Internet access - information, transactions, eCommerce PIM - connected electronic organiser, OTA synch Internet access is different from PC/IE5 access Mobile internet will substitute and extend internet value Not about a graphical experience necessarily More about availability Mobile phone is a good ID - inherently more secure than a PC

25 Core Benefits Connected Electronic Organiser Mobile Feature Phone
Dial/answer Contact SMS Contact Fax Contact 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 Very aggressive roadmap Launched Feb , web access Fall corporate intranet, transaction services, information services, data base and Entertainment services Mid Colour terminal, groupware services Fall kJava, games download Spring G roll out - Music, video, TV conference etc.

27 WID Design Issues

28 Design trade-offs Data Phone Performance Availability 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 Data Nokia 9110 Palm VII RIM Blackberry Smartphone Mobile phone Phone Performance PC Notebook Series7 Data vs phone chart compares wirelessly connected devices - all have aerials Performance vs availability compares non-wireless (except IrDA) data devices Combine the two trade-offs and then add in 1-box vs 2-box and you have a lot of design choices The point is that there is no obvious winning trade off Conclusion 1: Device market is likely to be segmented Conclusion 2: There will be market successes and failures Like playing high-stakes battleships in n-dimensional space Series5 Revo Palm III Availability

29 Form factors 2-box 3-box Phone IrDA or Bluetooth Handheld Computer
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? IrDA or Bluetooth 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 Web clipping 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

43 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, , backup, installing applications Psion producing EPOC client and corresponding services See

44 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 15

45 Wireless broadband? Speed will drive market growth
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 Megabits Per Second 1,000 500 GSM GPRS EDGE UMTS Today

46 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

49 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

50 World-wide Adoption

51 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

52 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 192 Kbps Audio S2 192 Kbps Audio S3 96 Kbps Data S1 64 Kbps Audio Service 3 Examples of data rates: Stereo Music Service Kbps Mono Music Service 96 Kbps Mono Speech Service 64 Kbps Data Service (multiples of 8 Kbps) 64 Kbps Data Service 1 Note: The sub-channels can be dynamically reconfigured by the Multiplexer without interrupting the audio flow

53 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

54 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

55 Problem for Java to solve
NT, Unix, Linux, Solaris, MVS, AS400, VMS, legacy Server Problem for Java to solve Desktop Windows Devices EPOC, CE, PalmOS, Linux, JavaOS, OS/9, Proprietary

56 Java 2 Configurations Profiles CDC = Connected Device Configuration
CLDC = Connected Limited Device Configuration (KVM) MID = Mobile Information Device

57 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 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

58 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

59 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
