industry value chains
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

i mode
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
design trade offs
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

  • 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
slide36
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

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

wireless broadband
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

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)

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
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

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

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
