Is there any difference between the near-field model and the far-field model? What is the classification based on? Near-field model usually considers the scenarios over high frequency band and the short distance between the transmit and receive. Due to short wavelength, the AoA at each receiver antenna appears different properties and values. For far-field model with large wavelength and long distance, the AoAs at different antennas of receiver usually have similar values. Usually, mmWave system over indoor scenarios adopts near-field model for research.
