C-MTC is Critical Machine type communications that play an important role in the mobile network society and it has generated good revenue for telecom operators. With the rapid development of embedded devices, MTC is becoming the dominant communication paradigm for various emerging smart devices. MTC has been formed by 3GPP and it is characterized by entirely automatic data generation, actuation, processing, and exchange between intelligent machines with or without the low intervention of humans. MTC starts to play an increasing role in cellular networks and efforts have been put in the LTE releases. MTC is also known as URLLC (Ultra-reliable low latency communications) which is relevant to real-time control and automation of dynamic processes in automated cyber-physical systems such as industrial process control.
