In 4G and earlier generation systems, frequency bands of above 6 GHz have not been used due to difficulties involving mobile communication systems, for example, higher propagation loss. Use of frequency bands above 6 GHz is a new challenge for the development and operation of mobile communication systems. It is important to know the fundamen- tal characteristics of above-6-GHz bands used in 5G radio. Propagation measurements and field experiments are essential to comprehend the
