Millimetre wave communication for 5G iot applications

Abstract

Mobile communications industry is going through an era of very rapid advancement as multiple major innovations are about to take place. Fifth generation (5G) of mobile communication systems is developed to become an all-encompassing solution to fundamentally every broadband wireless communication need of the next decade. Since both the communication and electronic technologies are matured enough, machine-to-machine communication is also about to take off, placing a completely new set of demands on the wireless networks. As the spectrum is already limited in the conventional sub 6 GHz bands, in order to generate efficient applications for the Internet of Things (IoT) within the 5G systems, utilization of new frequency bands are needed. Comprising, both licensed and unlicensed, ample bandwidth, millimetre wave (mm-wave) band is the primary candidate for adoption. In line with these, in this chapter mm-wave band is analyzed for use in 5G IoT implementations. Subsequent to introduction, a brief description of mm-wave band channel characteristics is provided. Then, enabling physical layer techniques of modulation, error control coding and multiple input multiple output are reviewed from the 5G mm-wave point of view. Following conclusions, the chapter ends with open research issues and future research directions.
