Overview of wireless personal communications: Microwave perspectives

The role of microwaves is discussed in achieving the future wireless personal communications (FWPC) system. An overview of the FWPC system is presented and the challenges to meet its demands are examined. Special attention has been paid in defining ti-ie research challenges in the light of microwave perspectives, Among several research challenges, the key challenges are briefly described, such as propagation modeling, antenna diversity and millimeter waves. The description of their potentialities narrates the state of the art of future wireless personal communications. it outlines some of the prospective evolution of FWPC systems and expects to draw the research interest of the microwave community in the creation of a ''Global Village.''
