With the advent of mass produced cellular telephony, wireless communication is about to revolutionize the way we think about information systems. In the near future it is generally believed that entertainment, personal computing and communication industries will merge and that the organizations and consumers will demand their services `on the move´. This paper will address how new technologies will enable future mobile distributed computing and communication systems and discuss what their impact may be on the behavior of users and their organizations. We will focus on some important trends in future mobile[21] and wearable/implantable computing[10]. Some of the limiting factors and key research and engineering problems are outlined. This paper demonstrates that future wireless applications and systems have to cope with a wide variety of heterogenous infrastructures ranging from short range local area high speed (100Mbit/s) systems to low speed long range and wide area satellite based systems.
