Research challenges in future wireless personal communications: microwave perspectives

Microwave\´s role is discussed in achieving the Future Wireless Personal Communications (FWPC). An overview of the FWPC system is presented and the challenges to meet its demands are examined. Special attention has been paid in defining the research challenges in the light of microwave perspectives. Among several research challenges, the key challenges are briefly described, such as propagation modelling, antenna diversity and millimetre waves. The description of their potentialities narrates the state-of-the-art of the future wireless personal communications. It outlines some of the prospective evolution of the FWPC systems and expects to draw the research interest of the microwave community in the creation of a "Global Village".
