The inherent characteristics of mmWave brings some advantages and challenges. We have summarized these characteristics and have considered the same while building the planning scenarios. mmWave Advantages and Challenges 1. Bandwidth: Large amount of spectrum available in mmWave which allows standards body to design/standardize large channel bandwidth. 3GPP has standardized bandwidth of 50 MHz up to 2000 MHz depending on mmWave band under consideration. Due to large channel bandwidth, it is the ideal choice for operators to build high-capacity networks. Advantages
