Introduction to massive Machine type communications
With the advent of 5G mobile communications, mmWave frequencies will be widely used to support a large number of users with high data rates and low latency. To provide such new services, some mmWave Massive Machine Type Communications (MmMTC) technologies have been studied and investigated. This article describes a brief overview of the related research results and applications of these technologies. At present, several MmMTC systems are under research in various countries, such as Japan. The “mMTC” concept is based on the extension of LTE/5G to support massive machine type communications (MMTC), which may enable a significant increase in the number of IoT devices that can access a network. Its deployment, however, goes hand-in-hand with key technical challenges that are not insignificant. Massive machine type communications (mmTC) is a new concept to share computing resources between heterogeneous machines in a seamless manner. mmTC ensures reliable, secure and efficient data localization. In some cases, this can dramatically reduce energy consumption of terminals and networks. Machine type communications (MTC) are the future of 5G networks, and mMTC is the most promising technology in this new era. MTC devices can range from small sensors to smart cars, but they share two things in common: low capacity requirements and high data rates. In 5G, massive MTC communications are used to provide the capability of commissioning different services in a mobile environment. These services can be provided across a wide range of scenarios such as connected homes, public transport and cities. These scenarios have specific requirements in terms of data rates and latency. Users also expect low power consumption and low cost modules as well as rapidly evolving performance in response time, throughput and coverage. All these can only be guaranteed by an efficient radio access technology for massive MTC communications. Massive machine type communications (mMTC) is a wireless system for communication among machines. It makes use of the IoT as well as 5G’s high data transmission rate, low latency, and network traffic optimization. In addition to supporting multiple connections, it also optimizes data transfer and mobility by decreasing the amount of data that needs to be sent through each connection. This can help reduce energy consumption while improving communication efficiency. 3GPP Release 15 addresses many key functionality and performance aspects for massive machine type communications (MTC) in 5G. This document provides a brief overview of some of the capabilities and features that work in conjunction with and complement the other 3GPP specifications. This document presents an overview of MTC and its role within a converged mobile network architecture, the requirements that have been defined in the 3GPP context for MTC devices, services, applications, components and interfaces aimed at enabling these devices to operate seamlessly in the 5G network environment. Massive M2M communications comprise a large number of small machines that communicate with each other and deliver or receive data services. In 5G, the massive machine type communication (mMTC) technology provides new opportunities for IoT, machine-to-machine communications and smart cities solutions. It also delivers new functionality in terms of supporting more devices and providing more reliable connectivity to support faster data transfer rates.
