Analysis of Outdoor to Indoor Penetration Loss for mmWave Channels

With the continuous development of science and technology, 4G can no longer fully meet the needs of human beings, and the era of “5G” is coming. 5G technology refers to the fifth generation of mobile communication technology, but it does not only add “1G” to 4G technology, but is superior to 4G technology in many performances. In terms of network transmission rate, the download rate of 5G is more than 10 times that of 4G. Otherwise, the 5G new radio uses millimeter wave (mmWave). mmWaves belongs to a range of frequencies from 30 GHz to 300 GHz which means 10 mm and 1 mm of wavelength. mmWave atmospheric absorption and rainfall fading, building and forest have a large impact, and communication distance is severely limited. In this work, we have studied and analyzed the outdoor to indoor penetration Loss for mmWave channels 28, 38, 60 and 73 GHz for different scenarios with NYUSIM model which is developed by researchers at New York University.
