Embodiment Construction

[0024] The present invention will be further described below in conjunction with drawings and embodiments.

[0025] The embodiment adopted in the present invention is: the millimeter wave outdoor intelligent passive coverage method adopts the direct irradiation coverage method in the direct area 21 of the base station 1, and adopts the method of the passive reflector 3 irradiation coverage in the shadow area 22 of the base station 1, to improve The signal strength of the shadow area 22 improves the channel characteristics of the shadow area 22; the position of the base station 1 is located at the intersection of the corridor 41 without an obstruction 4 in space as far as possible, or is located in an open place without an obstruction 4 nearby, so that the service area 2 The proportion of the inner direct area 21 is relatively 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 ...

Abstract

A millimeter wave outdoor smart passive covering method is provided. Direct irradiation coverage is applied to a direct irradiation area (21) and passive reflector (3) irradiation coverage is appliedto a shade area (22). A base station (1) and the passive reflector (3) are located in such a way that a base station (1) signal can reach a shade area (22) path (5) via the passive reflector (3) by reflections as few as possible and passing by a total distance as short as possible. The beam direction (61), the number, and the polarization direction (62) of reflection waves of the passive reflector(3) can be adjusted and changed in real time according to needs. The method reduces the path loss of large-scale millimeter-wave propagation, decreases a loss factor, improves the path loss of the shade area (22), improves the independence of a MIMO channel, can adjust the beam quantity and features of the shade area (22) according to needs, and is efficient in energy, wide in frequency band andlow 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 intelligent 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 millimeter waves is gr...
