The cellular Internet of Things – technologies, standards and performance

With each new generation, cellular systems have evolved to provide support for new services and applications. Currently the fifth generation (5G) radio access network is under development and an important pillar in this project is support for the Internet of Things (IoT). Ericsson has since 3GPP Release 13 contributed to this development with the design of three new technologies for support of massive Machine-Type Communications (mMTC). mMTC provides wireless connectivity for large number of network-enabled devices. This work is covered in detail in the recently published book ‘Cellular Internet of Things – Technologies, Standards and Performance’ authored by me and my colleagues Mårten Sundberg, Y.-P. Eric Wang, Johan Bergman and Joachim Sachs.

Enhanced 4G LTE coverage for Machine-Type Communications and Internet of Things

Support for Machine-Type Communications (MTC) and Internet of Things (IoT) in cellular networks is being drastically improved with the recent launches of products based on 3GPP Release 13. Improvements have been introduced in both 2G GSM networks and 4G LTE networks as well as in the form of a new radio interface optimized for narrow frequency band allocations. These are referred to as EC-GSM, LTE-M and NB-IoT, respectively. In this blog post we focus on the 4G LTE improvements for MTC/IoT known as LTE-M in the areas of low device cost, long battery life, and deep coverage.
