Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] The embodiment adopted in the present invention is: the millimeter-wave outdoor passive coverage method adopts the direct irradiation coverage method in the direct exposure area 21 of the base station 1, and adopts the passive reflector 3 irradiation coverage method in the shadow area 22 of the base station 1, to improve the shadow The signal strength of area 22 improves the channel characteristics of shadow area 22; the location of base station 1 is located at the intersection of corridor 41 without obstruction 4 as much as possible in space, or is located in the open place that does not have obstruction 4 nearby, so that in service area 2 The proportion of the direct area 21 is large, and it is also convenient for the signal of the base station 1 to reach the shadow area 22 through as few reflections as possible and the shortest possible path 5; the passive refl...

Abstract

A millimeter wave outdoor passive covering method is provided. A direct irradiation covering method is applied to a direct irradiation area (21) of a base station (1) and a passive reflector (3) irradiation covering method is applied to the shade area (22) of the base station (1). The base station (1) is located in such a way that a base station (1) signal can reach the shade area (22) by reflections as few as possible and passing by a path (5) as short as possible. The passive reflector (3) is located in such a way that base station (1) signal reaches the shade area (22) path (5) via a one-stage passive reflector (31) or a multi-stage passive reflector (32) by total reflections as few as possible and passing by a total distance as short as possible. The method reduces the path loss of large-scale millimeter-wave propagation, increases the number of independent channels, improves the independence of a MIMO channel, does not use a power supply, and is efficient in energy, wide in frequency band and low in cost, and liable to fuse with conventional environment and buildings.

Description

technical field [0001] The invention relates to mobile communication, in particular to a millimeter wave outdoor passive coverage method. Background technique [0002] The rate of mobile communication is getting higher and higher. In order to meet the needs of high rate, the operating frequency of mobile communication is also getting higher and higher, entering the millimeter wave frequency band. In an urban environment, buildings have a blocking effect on the propagation of millimeter waves and become obstructions for millimeter wave propagation. The area blocked by the obstruction is the shadow area of ​​millimeter wave propagation. The propagation of the millimeter wave in the shaded area mainly depends on the diffraction of the millimeter wave, but the wavelength of the millimeter wave is relatively short, and the diffraction ability of the millimeter wave is much lower than that of the lower frequency band. Therefore, the path loss of the millimeter wave is greater tha...
