Tutorial: Emerging 5G and IoT: Fundamentals and Applications


The tremendous increase in the demand for data rates due to bandwidth-hungry applications, such as video and virtual reality, the explosive growth in the number of devices, and the advent of new services have lead to intensive efforts of the research community to develop the fifth generation (5G) wireless networks and beyond. Industry players such as Ericsson, Huawei, Nokia, Qualcomm and Intel, as well as academia have been researching various technologies to meet the 5G requirements like 1,000 times increase in the network capacity, 1,000 times increase in the peak data rate, 100 increase in the energy efficiency, massive connectivity, low latency and ultra reliability. The goal for 5G is to be deployed by 2020, and the 3rd Generation Partnership Project (3GPP), which unites seven telecommunications standard development organizations, has been intensively working on the 5G New Radio (NR) standard. The upcoming generation of wireless represents rather a revolution than an evolution, and several technologies are considered to enable it, such as non-orthogonal multiple access, massive multiple-input multiple-output, millimeter wave, full duplex, and cloud-radio access network. In the first part of the tutorial, the 5G wireless networks will be introduced, with focus on their requirements, case studies, as well as enabling technologies. Additionally, challenges in measurements required in the 5G context will be presented.

5G aims to provide massive machine type connectivity, which basically represents the Internet of Things (IoT). Due to their large coverage, 5G networks represent a perfect match for supporting the IoT communications. However, new technologies need to be applied to accommodate IoT communications, which can be rather asynchronous and carrying a reduced payload. The NB-IoT and LTE-M standards which support IoT communications within LTE will be introduced as part of the tutorial. In addition to cellular wireless, other low-power wide area networks have been developed for IoT, such as LoRa, Ingenu and Sigfox. A brief discussion of their corresponding technologies will be also included.

The IoT will revolutionize our daily life, as well as the way many industries will be operating.  Representing a massive number of connected objects, which are able to collect data using embedded sensors, IoT finds applications to smart homes and cities, healthcare, agriculture, environment and industry. For example, IoT can significantly contribute to support patients’ health, and can also boosts their engagement and satisfaction by allowing better interaction with their doctors or physiotherapists, which can also improve the rehabilitation outcomes. Further, through integrating sensors and inter-connecting them over the Internet through specific communication protocols, intelligent recognition, location tracking, monitoring and management can be achieved in the context of smart cities. The tutorial will focus on the IoT applications to healthcare and smart cities. Elements of instrumented, inter-connected and intelligent components and how Internet and Sensors can help to develop a smart city will be presented. Furthermore, the possibility to integrate the information provided by the daily use of the smart physical rehabilitation equipment, such as smart walkers and crutches, wearable muscle activity monitors, force platform, and wearable accelerometers will be discussed. Additionally, smart equipment and natural user interfaces that are employed to extract information about patients’ balance and movement characteristics will be introduced.

The tutorial will provide on overview of the emerging 5G wireless networks (requirements, cases studies, enabling technologies), IoT through 5G and other low-power wide area networks, as well as IoT applications with focus on the healthcare sector and smart cities. Aspects related to instrumentation and measurement will be emphasized throughout the tutorial.
