With the explosive expansion of wireless communication and its continuously evolving systems, design of emerging solutions require appropriate mechanisms of testing, validation and verification. In this respect, a frequently adopted option is design of test beds to validate algorithms and implementation aspects. Some of the currently available test beds have evolved into reliable platforms of design formulation and validation. Here, the authors provide certain insights into the design of test beds related to high data rate wireless systems with focus on Multi Input Multi Output (MIMO) based systems. They review some of the relevant details of a few known designs and outline certain issues and challenges related to design of test beds that serve as proof of concept platforms for emerging technologies.
