Ubiquitous Computing MOBILE DATA COMMUNICATION TECHNOLOGY • Definition A device which enables the access to the information on the internet through the mobile phones, ANYTIME, ANYWHERE. Different from the Mobile Data Service where the access to the information is gained by the mobile phones connected to the laptops, HPC, and PDA etc. • Significance The Fusion of the Mobile Network and the Wired Network which brought the progress in the New Paradigm Example) Internet = Inter-Network = Network of Network Telecommunication = PSTN + PLMN Realization of the Goal of the Information Society : ANYTIME, ANYWHERE • Characteristics Mobility : Easy to carry and Convenient to use while moving Personalized : Much higher User-friendly than PC (Mobile Subscribers > Internet Subscribers) GLOBAL MARKET TRENDS FOR MOBILE DATA SERVICE • Originated in the Western Europe The average mobile penetration of the Western Europe is 80 % (compared with 50 % in the U.S.) It used to be expected that the number of mobile internet users would exceed that of the wired internet users by the end of 2004. At present, however, the mobile internet users are less than 5 % of the total number of the mobile subscribers. The development of the mobile data service in the Western Europe centered around SMS, and WAP traffic forms less than 10 % of the total data traffic. Failed to make service-focused progress while persisting in technology standards.
