With the development of Long Term Evolution Advanced(LTE-A) and LTE-B, the Third Generation Partnership Project( 3GPP) has presented various services in which the advantages of high data rates are implemented.
3GPP has also specified corresponding LTE services for applications with low data rates, such as those used in the Internet of Things ( IoT) and machine-to-machine communication( M2M). Thus LTE-MTC, Machine-Type Communication (MTC), also known as LTE-M, which stands for Machine to Machine Communication (M2M). LTE-MTC is a concept for Low Power WANs( LPWAN) and operates at low data rates.
Machine-Type Communication (MTC) is characterized by the automatic generation of data, data exchange and data processing between intelligent entities, without human intervention. MTC components have extremely low power consumption and should ensure a battery life of 15 years. MTC communication is used in machine-to-machine (M2M) communication. For example, in smart meters, in fleet management of motor vehicles or in medical devices for patient monitoring, among others. For these applications, there is LTE M2M (LTE-M) and Narrow Band LTE( NB-LTE). The technology is supported by low-cost MTC devices with very low data rate and lowest power consumption, which can be used in private homes and office buildings.
The first version of LTE-MTC was released under Release 8 and worked with Category 1 devices. The later version, which met all power consumption and cost and requirements, was released under Release 12 and relied on Category 0 devices. Two MTC variants are used in5th generation( 5G) mobile networks: ultra- reliability machine-type communication ( uMTC) and massive machine-type communication( mMTC). Both methods are aimed at communication between devices, objects and things and offer reliable communication in the Internet of Things (IoT).
