TL;DR: In this paper, the authors comprehensively review the most prominent existing and novel M2M radio technologies, as well as share their first-hand real-world deployment experiences, with the goal to provide a unified insight into enabling machine-to-machine architectures, unique technology features, expected performance, and related standardization developments.

TL;DR: This article addresses the market-changing phenomenon of the Internet of Things, which relies on the underlying paradigm of machine-to-machine (M2M) communications to integrate a plethora of various sensors, actuators, and smart meters across a wide spectrum of businesses.

TL;DR: An overview of several features included in 3GPP to accommodate the needs of M2M communications, including changes in the physical layer such as enhanced machine type communications, and new MAC and higher-layer procedures provided by extended discontinuous reception are presented.

TL;DR: An overview of features introduced for NB-IoT in LTE Release 14, including increased positioning accuracy, increased peak data rates, the introduction of a lower device power class, improved non-anchor carrier operation, multicast, and authorization of coverage enhancements are provided.

TL;DR: It is established that the availability of alternative connectivity options, such as D2D links and drone-assisted access, helps meet the requirements of mcMTC applications in a wide range of scenarios, including industrial automation, vehicular connectivity, and urban communications.
