60 GHz Wireless Data Interconnect for Slip Ring Applications

The first part of the article summarizes the main requirements imposed by modern industrial applications on a communication interface between mechanically rotating subsystems. The second part attempts to classify numerous data interface technologies employed in these subsystems today according to the type of mechanisms used to transmit data between a rotor and a stator. It gives a concise overview of these technologies and discusses their main advantages and disadvantages. The third part of the article proposes a novel 60 GHz wireless solution for high speed, low latency communication that enables realization of advanced data interface architectures in slip ring assemblies to meet the demanding requirements of new industrial scenarios.
