ABSTRACT
This chapter describes some of the foremost millimeter-wave (mm-wave) fifth generation (5G) Internet of Things (IoT) usage scenarios. It also describes the wireless local area network standardization activities towards the initiation of mm-wave for 5G IoT purposes, and explains the electromagnetic wave channel characteristics in the 30–300 GHz frequency range. The short range of mm-wave is especially suited for indoor networks. The presence of walls and other impervious objects ensure reflections within the confines of the network coupled with small absorption losses. The use of a very high number of antennas in massive multiple input–multiple output make mm-wave systems resistant to interference and provide the network with a higher number of possible signal paths, and thus the performance in terms of data rate and link reliability improves. Probabilistic models can be used to evaluate an expected behavior for outdoor networks more easily because the network geometry is active.
