In this paper, we present the roles played by millimeterwaves in the realization of an Internet of Things (IoT) society. Millimeterwaves are becoming essential frequency resources, enabling ultra-highspeed wireless networks supporting massive data traffic and high-resolution sensor devices. Multiple antenna technologies such as phased arrays, sector antennas, and MIMO signal processing are key technologies for putting these into practical use. In this paper, various examples of integration of

We also propose applications to ITS for an IoT society, combining millimeter-wave wireless access and radar sensors, and discuss technical issues to be solved in the future.
