Introduction
The M2M Department is focused on both theoretical and experimental research in the field of Machine-to-Machine (M2M) Communications for the Internet of Things (IoT). The automated communication between autonomous devices will facilitate unprecedented new applications that will create a revolution in our daily life and in the efficiency and operation of industrial processes. However, many challenges need to be solved in the technical domain before true M2M revolution occurs.
This department conducts research at the lower layers of the protocol stack to facilitate M2M applications with particular focus on Radio Resource Management, Scheduling and Medium Access Control for M2M communications.
