Abstract:
There are explosive growth in the number of IoT (Internet of Things) devices. Long Term Evolution(LTE) is prospering as one of the promising mobile communication systems. LTE-based machine type communications have become an important research topic. There are several advantages using cellular wireless M2M (machine-to-machine) connectivity to serve IoT devices. In the next generation 5G cellular wireless networks, machine-to-machine communications will play a key role. Based on ITU study, 5G wireless is aimed to enable three types of services: enhanced mobile broadband communications, massive machine type communications (or massive M2M) , and ultra-reliable and low latency communications (mission-critical M2M). On the other hand, fog computing is a promising approach to provide low-latency services. Fog-RAN (Fog-based Radio Access Network) applied the edge computing paradigm along with the next generation RAN design to meet the low-latency application demands in 5G. In this talk, opportunities and design challenges of mission-critical M2M communications and fog-based radio access network will be discussed. We will also discuss the recent standardization and research activities in this area.
