【Abstract】 With the rapid development of mobile communications, low frequency spectrum has been unable to meet requirements of 5G mobile communication network. Therefore, high frequency spectrum resources should be effectively used to enhance transmission rate and system capacity. The basic concept and related background of millimeter wave communication were introduced. The effects of atmosphere’s absorption, cloud, fog, rain and dust on millimeter wave attenuation were analyzed. In addition, millimeter wave compound atmospheric attenuation was analyzed. The aforementioned research has a certain reference significance to the full spectrum access in 5G mobile communications.更多还原
