EMTC is an application scenario of the Internet of Things. It is ultra-reliable and low-latency. It focuses on the communication needs between things. EMTC technology is an important branch of all things interconnection technology. Based on LTE protocol, LTE protocol has been tailored and optimized for better communication between things and for lower cost. EMTC is deployed based on cellular network, and its user equipment can directly access the existing LTE network by supporting 1.4MHz radio frequency and baseband bandwidth. EMTC supports the peak rate of up-and-down maximum 1Mbps, and can support rich and innovative applications of IUB.
