wireless advantage
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
challenges in wireless implementation
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.)
challenges in wireless implementation5
Challenges in Wireless Implementation
  • On the network side
    • Less bandwidth
    • More latency
    • Less connection stability
    • Less predictable availability

what is wap
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
wap offers bearer independence
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

wap provides device independence
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
wap provides a microbrowser optimized for wireless devices
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
converging with an xml world
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
so why wap
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
wap benefits
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

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.
i mode structure
I-Mode Structure

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