Abstract

The future Internet of Things will integrate sensing and wireless communications. Among the multiple types of sensors to be used, sensors based on the radar principles are of interest for several applications, namely automotive. Dual functionality devices that integrate reflectometry and communication capabilities will be important to reduce development costs through the reuse of modules and to optimise the usage of radio resources, e.g. spectrum. This paper reviews the main trends that push for the merging of radar type sensors and wireless communications (RadCom). It presents the most important use cases that can be currently foreseen and identifies the main technology trends and issues to reach a mature technology, focusing on OFDM type waveforms that will enable a smooth integration with 4G and 5G.
