Trends in digital wireless communications

Summary form only given. Successful implementations and large-scale rollouts of cellular (high-tier, fully mobile) and cordless (low-tier, limited-mobility) systems have been achieved in several markets and with a handful of different communication system approaches. We will examine one or two examples of design practices at the systems and circuit level to appreciate the current state of the art now in high-volume deployment. Strong moves to deregulate communication services and willingness to open large segments of the RF spectrum for novel new uses mark the trends in both the US domestic and many international administrations. These events are guaranteed to cause rapid acceleration of the acceptance of wireless services by the general public while also moving the choice of RF carrier frequencies upward.
