Digital Front End Transceiver Technology for Wireless Infrastructure

Abstract

This article sets out to explore the dramatic shifts in cellular radio technology. Within a relatively short space of time we have seen five distinctive generations of cellular technology roll out, each generation delivered enhancements in terms of quality of service while at the same time enabling new features and services. The evolution could not have happened were it not enabled by a parallel evolution in the cellular basestation. In this article, we focus on one of the key enablers; the radio unit digital front end transceiver.
