| Abstract [eng] |
While wireless technologies gain popularity in business environment they are rarely used as part of information systems. Lack of complex solutions covering technical aspects of technologies and theoretical aspects of information systems is felt, while new wireless technologies gain quick adoption in business. Fast spread of WiFi is followed by “WiMAX” – number of this technology based solutions is growing fast. But there is still lack of information systems models which would fit possibilities of current technologies and requests of modern business. Analysis of most popular wireless technologies is followed by conclusion, that only analysis of “WiMAX” and WiFi is logical considering native qualities of technologies analysed. Review of current information system models reveals, that decision making and expert systems can be treated as working on same model same as information and data processing systems can be also threaded. Analysis of existing information system models is fulfilled by adding qualities of wireless technologies and two new models of wireless technologies based information systems are formed. They both are based on essential models of decision making and information processing systems but use wireless technologies where its possible keeping in mind technical possibilities – in connecting input/output parts with main information systems components. These conclusions are followed by research of Lithuanian IT companies which concludes, that there is a high interest in wireless technologies and lack of competence and trust implementing them it information systems. This shows that models formed can be widely used in business environment when implementing wireless technologies based information systems. For full implementation fuller adoption of “WiMAX” or similar quality of service (QoS) technology would be preferable, but models formed can be also used on WiFi base. |
