WID Design Issues :WID Design Issues


Design trade-offs :Design trade-offs 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 Phone Smartphone Palm VII RIM Blackberry Nokia 9110 Mobile phone Performance Availability Series5 PC Notebook Palm III Revo Series7


Form factors :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? Form factors Phone Handheld Computer IrDA orBluetooth Radio Handheld Computer Bluetooth Headset 2-box 3-box


Application models :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

Technologies :Technologies Microbrowsers SyncML GSM -> GPRS -> EDGE -> UMTS Bluetooth Java DAB Speech recognition


Microbrowsers :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


WAP :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


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


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


Multimode Browser :Multimode Browser Data Source WAP Browser WAP Gateway HTML XML WML Opera Browser www.operasoftware.com


SyncML :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


Bluetooth :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


Wireless broadband? :Growth in Wireless Data Speeds 0 500 1,000 1,500 2,000 GSM GPRS EDGE UMTS Megabits Per Second Today 2000 2001 2003 Wireless broadband? 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


GPRS :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

Digital Audio Broadcasting :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


World-wide Adoption :World-wide Adoption


User Benefits of Digital Radio :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


DAB Multiplex :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 Audio Service 2 Audio Service 3 Data Service 1 Audio S1 192 Kbps Audio S2 192 Kbps Audio S3 96 Kbps Data S1 64 Kbps 1.5 Mbps Note: The sub-channels can be dynamically reconfigured by the Multiplexer without interrupting the audio flow Examples of data rates: Stereo Music Service 128-192 Kbps Mono Music Service 96 Kbps Mono Speech Service 64 Kbps Data Service (multiples of 8 Kbps) 64 Kbps


Broadcast Websites :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


WaveFinder – A Smart Antenna for the PC :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


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


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


Java on WID’s :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


Speech Recognition :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


Summary :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
