The design of PDA application schemes for wireless communication services

Current researches on PDA are emphasizing the technical issues such as the hardware organization or language for remote communication. However, the details of the wireless PDA services are yet to be defined. We need to know what kind of services can be conducted and what data should be transmitted in what manner in order to complete the service. This research provides a practical application layer design which examines the possible categories of wireless PDA services and, for each category, the necessary data formats designed for conducting the service. The aim is to figure out an organized and feasible application scheme which, when being employed, makes the wireless PDA services viable.
