Machine-type communications as part of LTE-advanced technology in beyond-4G networks

Machine-Type Communications is an important part of the infrastructure of LTE. This technology connects with all the other new technologies in mobile communications. In this paper, we describe Machine-Type Communications and its relation with other technologies, e.g. heterogeneous networks and device-to-device communications. We will show a simple model of Machine Type Communications in the LTE-A network (random access procedure) and discuss M2M technology. First we describe the concept of heterogeneous networks and device-to-device communications. After that we consider the Machine-Type Communications and power consumption problem.
