Conceptual and operational definition of system complexity in the domain of Wireless Internet via Mobile Technology

Acceptance of new information technologies by their intended users endures as an important issue for researchers and practitioners of information systems. Research has shown that the complexity of technology is an important factor influencing user acceptance, but few studies have been done in conjunction with Wireless Internet via Mobile Technology (WIMT). This study defines and explores four aspects of the System Complexity construct in the WIMT domain (Efficiency of Data Transfer, System Functionality, Interface Design and Capacity of Mobile Devices). A measurement instrument is developed and validated for this construct. Implications for theory and practice are discussed with suggestions for future research in this area.
