Introduction

• Wireless technology turns e-business into
  m-business, or mobile business
• Current applications
• Conduct online transactions
• Make purchases
• Trade stocks
• Send e-mail
• Future applications
• A wireless office, where computers, phones and
  other office equipment are all networked without
  cables

Wireless Devices

• Wireless development
• First-generation wireless technology was the
  cellular phone
• Second generation wireless technology, which
  includes digital cellular phones, is currently in
  use worldwide
• Third generation, or 3G technology will enable
  wireless devices to send and receive data as much
  as seven times faster than a standard 56K modem
• Wireless devices
• Personal digital assistants (PDAs)
• Digital cellular phones
• Two-way pagers

4
Wireless Devices (cont.)

• Outside the United States, mobile phones are the
  preferred medium for getting information and
  making e-business transactions
• Service is not universally available and still
  relatively expensive
• Limited bandwidth restricts the amount of data
  that can be sent over the wireless network
• Wireless devices have significantly smaller
  memory capacity and less powerful processors than
  desktop computers

m-Business

• m-Business
• e-Business using wireless devices with Internet
  access
• B2C marketplace
• Increased conveniences for consumers
• Frequent, small transactions
• Receiving news, sports scores, e-mail, coupons
  and advertisements
• B2B marketplace
• Salespeople can access product databases and
  place orders
• Address customer needs immediately
• Ordering and billing will be conducted remotely

6
Wireless Internet Access

• Code Division Multiple Access (CDMA)
• Each transmission is assigned a specific channel,
  giving the transmission the benefit of the entire
  bandwidth within that channel and reducing the
  possibility that a connection will be broken
• Able to assign each transmission on the network a
  unique code to ensure security
• Global System for Mobile Communications (GSM)
• Uses Time Division Multiple Access (TDMA) which
  takes multiple calls and assigns each call to a
  different time slot on the same radio frequency

7
Wireless Internet Access (cont.)

• 3G technologies
• EDGE (Enhanced Data for GSM Evolution)
• Cdma2000
• W-CDMA
• International Telecommunications Union (ITU)
• Establishes guidelines for 3G

8
Wireless Web Technology

• Three technologies are used to provide Web access
  to wireless devices
• Wireless Application Protocol (WAP)
• Web Clipping
• Microsofts Pocket Internet Explorer

9
Web Clipping

• Web clipping
• Allows users to take relevant pieces of a Web
  site and deliver it to a wireless device,
  eliminating excess content and graphics
• Palm devices use Web clipping
• Proxy server
• Lies between client (such as a Web browser) and
  Web server
• Query is received by a proxy server controlled by
  the wireless ISP
• Proxy server goes to the Web site and clips the
  necessary data
• The proxy server transmits the data back to your
  wireless device
• If the proxy server does not have the
  information, it passes the request to the regular
  server

10
Personal Digital Assistants

• Palm VII wireless handheld computer
• Query Application Builder (QAB)
• Web designers build Palm Query Applications
  (PQAs) to be installed on users Palm handheld
  computers
• With a PQA for a particular web site installed on
  the Palm, the user can view the tailored content
  for that web site

WAP and WML

• Wireless Application Protocol (WAP)
• Developed by Nokia, Ericsson, Motorola, etc.
• A set of communication protocols designed to
  enable different kinds of wireless devices to
  communicate and access the Internet
• Designed to standardize development across
  different wireless technologies worldwide
• Intended primarily for Internet-enabled digital
  phones, pagers and other handheld devices
• Uses Web sites specifically designed for wireless
  handheld devices that have small screens and
  low-bandwidth constraints

14
WAP and WML (cont.)

• Wireless Markup Language (WML)
• The scripting language used to create Web content
  to be delivered to wireless handheld devices,
  based on XML
• Removes unnecessary content from Web pages
• WML tags are used to mark up a Web page to
  specify how the page should be formatted on a
  wireless device
• WML works with the WAP to deliver the content
• Similar to HTML, but it does not require input
  devices
• Microbrowsers
• Designed with limited bandwidth and limited
  memory requirements
• Access the Web via the wireless Internet

15
WAP and WML (cont.)

• How wireless Internet works
• A WAP gateway, which acts as a proxy server,
  receives the request, translates it and sends it
  to the appropriate Internet server
• Server responds by sending the requested WML
  document
• The WAP gateway parses this document's WML (i.e.,
  it analyzes the WML document, checking it for
  correctness) and sends the proper text to the
  digital phone
• Deck
• A WML document
• Card
• Consists of one user interaction, providing the
  WML browser with a small, self-contained document
  for browsing

Software Applications for Wireless Devices

• No widely accepted standard for wireless
  development
• Developers are often required to develop multiple
  applications
• Microsoft Pocket Internet Explorer
• Reformats complete Web pages as they are
  downloaded from the Internet for display on the
  Pocket PC
• Allows Pocket PC users to access most of the
  content currently available on the Web and
  eliminates the need to tailor Web content for
  delivery to handheld devices
• PacketVideo
• Specializes in wireless video technology for
  mobile devices

Wireless Local Area Networks

• Easier to install and maintain without disrupting
  an office
• Computers can easily be moved without having to
  install a new network connection in each location
• Radio Frequency WLANs (RF WLANs)
