Mobile Web Access M-Business
Ubiquious Web • Everyone would like to access the Web from • Anywhere • Anytime
Devices used • Mobile Phones • Personal Digital Assistants (i.e. Palm Pilot, BlackBerry) • www.palm.com • www.blackberry.com • Small information appliances • Car navigation systems • Laptop Computers
B2C Wireless applications • Consumer uses include • Calendar, address book, phone numbers… • News, weather, sports scores… • Trade stocks • E-mail – Continuous communication
B2B Wireless Applications • Sales and Service personnel • Access product databases • Place orders • Answer customer questions
Considerations with Mobile Access • Regional Carriers • Network Characteristics • Bandwidth – 9.6 to 14.4 Kbps • Reliability – sometimes unreliable • Device characteristics • Screen and keyboard size – typically very small • Robustness – limited applications
Considerations with Wireless (cont.) • Not available everywhere • Can be relatively expensive • Less memory, less cpu power • Security issues • Radiation concerns (?)
Digital wireless communication technology • Currently used • CDMA – U.S. • GSM – Europe, Asia • PDC – Regionally in Japan
“New” Digital wireless communication technology • 3G Technologies • High speed wireless access • Streaming audio, video, etc. • EDGE • Cdma2000 • W-CDMA
Wireless Application Protocol (WAP) • A set of communication protocols • Standardization for wireless technologies • Designed for wireless devices • Small screens • Low bandwidth • Allows scalability across wireless networks
Wireless Markup Language(WML) • Scripting Language • Creates content for wireless devices • Based upon XML • WML tags used for markup • WML works in conjunction with WAP
Web Clipping • Formats data • Enables Access to relevant web information • Eliminates excess content and graphics • Used extensively by Palm, implemented using a proxy server
Other Technologies • Bluetooth • Communication between digital devices • Short range • High speed voice • High speed digital • Cross-platform • Microsoft Pocket Internet Explorer • Reformats downloaded web pages
Sites that provide Mobile access • Directory of Mobile sites • http://mfinder.cellmania.com/ • Mobile services and software • http://www.avantgo.com
Future of wireless devices • “All in one” devices • Combination of PDA’s and phones (Qualcomm, Kyocera) • Instant messaging, will become a standard feature • Text to speech technology • Wireless devices are projected to pass the 1 billion mark by 2003 (Gartner group) • Wireless connectivity market is projected to be worth $80bn by 2010 (Gartner group)
Summary • Wireless Technologies are used to connect to the internet (CDMA, GSM, PDC) • WML is used to create WEB content for wireless devices • WAP protocol • Encapsulates WML • Transmits information to the wireless device over CDMA, GSM, PDC, etc.
