Today, 25 August 2015 Prof. Eryk Dutkiewicz from Department of Engineering, Macquarie University, Sydney, Australia, visited us at the Meruya Campus, and gave a presentation entitled “Challenges of Machine-to-Machine Communications and Dynamic  Spectrum Sharing for 5G Mobile Networks “.

This talk presents the concept of Machine-to-Machine (M2M) communications and describes key emerging applications expected to be enabled by M2M. Existing and emerging standards are briefly reviewed for both access networks and mobile networks to support M2M communications. These include 802.15.4e and 802.11ah standards for access networks and enhancements of LTE mobile network standards. Technical challenges of M2M are described for both access and mobile networks. An overview of emerging 5G standards is given including a discussion of issues being addressed to enable the support of M2M communications and applications. One of the key challenges of 5G networks is efficient spectrum sharing.
