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 indoor 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 shadow The signal strength of area 22 improves the channel characteristics of shadow area 22; Passive reflector 3 includes one-stage passive reflector 31 and multi-stage passive reflector 32; The signal of base station 1 passes through the reflection of passive reflector 3, passes through Pass through indoor doors and windows and other places where millimeter waves are easy to penetrate, and reach the shadow area 22; the position of the passive reflector 3 makes the signal of the base station 1 pass through the primary passive reflector 31 or mul...

Abstract

The invention provides a millimeter wave indoor passive coverage method. A direct irradiation coverage method is adopted in a direct irradiation area (21), and an irradiation coverage method of a passive reflector (3) is adopted in a shadow area (22); the signal of a base station (1) passes through indoor doors and windows and parts where the millimeter wave is easy to penetrate through to arriveat the shadow area after being reflected by the passive reflector (3); due to the position of the passive reflector (3), the total number of reflections of the signal of the base station (1) on a path(4) of arriving at the shadow area (22) through the passive reflector (3) is reduced as much as possible, and the total distance is as short as possible. By adoption of the method, the path loss of millimeter wave propagation can be reduced, the number of independent channels can also be increased, and the independence of an MIMO channel is improved; and no power supply is used, so that the millimeter wave indoor passive coverage method has the characteristics of energy saving, wide working frequency bandwidth and low cost, and can be easily integrated with the existing indoor environment.

Description

technical field [0001] The invention relates to mobile communication, in particular to a millimeter wave indoor 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. Compared with electromagnetic waves with lower frequencies, the path loss of millimeter waves is relatively large, especially because the wavelength is relatively short, and the blocking effect of obstacles is also relatively large. Indoors, the partitions between the various rooms constitute an obstacle for the propagation of millimeter waves. It is difficult for millimeter waves to penetrate walls. Although there are open doors or windows, due to the weak diffraction ability of millimeter waves and strong linear propagation, usually It is difficult for the beam direction to be jus...
