These terminals are movable in space and are provided with wireless communication. The advantage of MIS is that they provide new value-added services due to their mobility and flexibility. They also render other services such as user access across multiple devices and channels, and the ability to perform collaborative work either in synchrony or otherwise. The book presents researches and studies performed by experts across the globe. Also included in this book is a detailed explanation of the various concepts and applications of mobile information systems. The readers would gain knowledge that would broaden their perspective about this field.
