  1. Wireless Web Access Survey Report John Lautmann Uma Chandrasekar

  2. Agenda • Wireless Advantage • Challenges in wireless implementation • Wireless Web Architectures • WAP • I-Mode • Comparison of WAP and I-Mode • Wireless LAN • Bluetooth

  3. Wireless Advantage • potential benefits through more flexible, mobile and personal channels of communication. • An opportunity to fundamentally transform customer relationships • Creative wireless solutions enable users to access information whenever and however they want. • Company can “push” data to customers in real-time • “Any device, Anytime, anywhere” mantra

  4. Challenges in Wireless Implementation • On the equipment side • Less powerful CPUs • Less memory (ROM and RAM) • Restricted power consumption • Smaller displays • Different input devices (e.g., a phone keypad, voice input, etc.)

  5. Challenges in Wireless Implementation • On the network side • Less bandwidth • More latency • Less connection stability • Less predictable availability

  6. Wireless Web Architectures Tier 1 Tier 3 Tier 2 Web Server Client Device Wireless Gateway Receiving Tower Wireless HTTP Browser • Disadvantages • Unusable without network • Poor usability • Poor performance • Poor battery life • Advantages • Fast time to market • Simple development effort • Works on all devices Browser-based wireless architecture

  7. Wireless Web Architectures Tier 1 Tier 2 Tier 3 Client Device Web Server Thick client Sync Engine Sync Server Receiving Tower Wireless Local data • Disadvantages • Complex development effort • Slow time to market • Client software distribution/support • Unavailable for cell phones • Advantages • Always available • Good usability • Good performance • Good battery life Thick Client Solutions

  8. Wireless Web Architectures Tier 1 Tier 2 Tier 3 Client Device Web Server AvantGo client AvantGo Server Receiving Tower Wireless Local Content • Disadvantages • Very poor usability • Client software distribution/support • Unavailable for cell phones • Advantages • Always available • Fast time to market • Good performance • Simple development effort Hybrid Solutions

  9. What is WAP? • An open, global standard that empowers mobile users with wireless devices to easily access and interact with information and services instantly. • A standard created by wireless and Internet companies around the world to make accessing the Internet as easy and convenient as using a cellular phone

  10. WAP – An extension of the Internet Model

  11. WAP Architecture

  12. WAP Offers Bearer Independence SMS • Allows Applications developed once to work across all networks -- today and tomorrow • Protects the Carrier’s investment in wireless data as networks evolve • Enables Mobile Device Manufacturers to use common code across product lines TDMA GSM USSD GPRS CDPD CDMA

  13. WAP Provides Device Independence • Allows applications developed once to work across devices from small handsets to powerful PDAs • Promotes consistent user experience across all of a carrier’s handset offerings • Encourages wealth of applications for handset manufacturers that implement the standard

  14. WAP provides a “microbrowser” optimized for wireless devices • Requiring minimal RAM, ROM, Display, CPU and keys • Providing carriers with consistent service UI across devices • Providing Internet compatibility • Enabling wide array of available content and applications

  15. Converging WithAn XML World • WAP is already prepared for convergence • Understanding the “module” effect • Content availability increases because less code is needed to render sites properly instead of re-writing whole sites • WAP complies with W3C’s recently approved XHTML standard

  16. So - Why WAP? • An open industry-established world standard • Based on Internet standards includingXML and IP • Committed to by handset manufacturers representing over 95% of the world market across all technologies • Supported by network operators representing over 200 million subscribers

  17. WAP Benefits • WAP delivers revenue opportunities for carriers • WAP offers a broad market for developers • WAP means increased sales for device, infrastructure and gateway manufacturers • WAP means freedom to the end user

  18. WAP’s “Killer Apps” • Location-based services • Real-time traffic reporting • Event/restaurant recommendation • Highly customized ads • Instant messaging-type “buddy” location • Enterprise solutions • Email access • Database access • A “global intranet” • Information updates “pushed” to WAP devices

  19. WAP’s “Killer Apps” • Gaming, Gambling and Entertainment • Online, real-time, multi-player games • Downloadable horoscopes, cartoons, quotes, advice • “M”-Commerce - Shopping on the go • Instant comparison shopping • Impulse buying • Location-based special offers and sales • Financial services • Banking, Bill-paying, Stock trading, Funds transfers • Travel services • Schedules and rescheduling • Reservations

  20. I-Mode • In addition to conventional voice communications, users can access a wide range of sites by simply pressing the i-mode key. • The convenient and useful service lineup includes mobile banking and ticket reservations. • I-mode employs packet data transmission (9600bps), so communications fees are charged by the amount of data transmitted/received rather than the amount of time online. • i-mode is compatible with Internet e-mail and can also transfer mail between i-mode terminals.

  21. I-Mode Features

  22. I-Mode Features

  23. I-Mode Features

  24. I-Mode Features

  25. I-Mode Structure Connecting to sites, receiving messages and transmitting e-mail are done via the DoCoMo i-mode center.

  26. Comparison I-Mode & WAP

  27. Comparison I-Mode & WAP

  28. Comparison I-Mode & WAP

  29. Wireless Network Characteristics • Low bandwidth / Wide coverage area CDPD • High bandwidth / Short distances 802.11a / 802.11b Bluetooth Infrared

  30. Infrared Lan interconnect • Can use to sync handheld devices with Avantgo • Use Microsoft ActiveSync to update handheld • Can connect to internet at speeds of up to 4Mbps

  31. Wireless Network Evolution

  32. Wireless Network Speed Comparison

  33. Wireless Network Uses

  34. Summary of Wireless Networks

  35. Wireless Network Security • 802.11b Wired Equivalent Privacy Protect wireless data to an equivalent level of privacy of wired networks • Uses 40, 64, 128 bit encryption • WEP2 standard (802.11e) in progress

  36. Mobile IP enables Wireless Freedom • Mobile IP provides users the freedom to roam beyond their home subnet while consistently maintaining their home IP address • Enables sessions to be maintained in spite of physical movement between points of attachment to the Internet or other networks
