ABSTRACT
Cellular phones have almost replaced conventional telephones for public use in Western European countries. Modern WAP enhanced phones or smart phones offer mobile access to the internet, anytime and anyplace. This technique therefore appears to be very attractive for transferring up-to-date information about the environmental situation to the public, i.e. air and water quality measurements or weather conditions as well as forecasted values of these processes. The Wireless Application Protocol (WAP) is the key technology in this respect. According to the upcoming importance of mobile internet access the WAP technology has great potentials to play an important role in the design of modern information services which are user centered. Because of upcoming environmental laws in Europe the citizen will gain the right to access the environmental information collected and stored by the public authorities. But due to size and resolution of the displays used in the actual versions of the cellular phones it is not sufficient to transfer the concepts and architectures known from internet information systems to WAP-based systems. It is rather necessary to develop special concepts for the design of WAPbased services, with a special focus on the appropriate structuring and presentation of environmental data. This paper gives an overview of the main problems WAP system designer had actually to deal with and shows concepts how to solve them. At the end of the paper we present two mobile environmental information services, which were realized on the basis of the presented concepts.
