Embodiment Construction

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

[0025] The implementation scheme adopted in the present invention is: the millimeter wave indoor intelligent passive coverage method adopts the direct irradiation coverage method in the direct irradiation area 21, and adopts the passive reflector 3 irradiation coverage method in the shadow area 22 to improve the signal strength of the shadow area 22 , to improve the channel characteristics of the shadow area 22; the passive reflector 3 includes a primary passive reflector 31 and a multi-stage passive reflector 32; the signal from the base station 1 is reflected by the passive reflector 3 and passes through indoor doors and windows, etc. The part where the millimeter wave is easy to penetrate reaches the shadow area 22; the position of the passive reflector 3 makes the total number of reflections of the base station 1 signal pass through the passive reflector 3 to the sha...

Abstract

The invention discloses a millimeter-wave indoor intelligent passive coverage method. Direct irradiation coverage is employed in a perpendicular incidence region (21), and a passive reflector (3) is employed for irradiation coverage in a shadow region (22). A signal from a base station (1) is reflected by the passive reflector (3), and then passes through an indoor window and other parts which allow millimeter waves to penetrate easily to arrive at the shadow region (22). The position of the passive reflector (3) enables the number of total reflections of the signal of the base station (1) from the passive reflector (3) to the shadow region (22) to be small as much as possible and enables the path (5) from the passive reflector (3) to the shadow region (22) to be short as much as possible.The wave beam direction (61) of a reflection wave (6) of the passive reflector (3), the number of wave beams and the polarization direction (62) can be adjusted and changed in real time according tothe business demands. The method can reduce the path loss of the millimeter waves, improves the independence of an MIMO channel, and can adjust the number of wave beams and characteristics of the shadow region (22) in real time according to the business demands. The method is characterized in energy saving performance, wide working band and low cost, and is liable to be integrated with a conventional indoor environment.

Description

technical field [0001] The invention relates to mobile communication, in particular to a millimeter wave indoor 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. 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 directi...
