Problems solved by technology

Because the matt glazed surface of the interior wall panel is relatively complicated to manufacture (two kinds of effect glazed glazed interior wall tile manufacturing methods), special matte dry powder is required, the cost is high, and its surface roughness and reflective color rendering index range It is difficult to control precisely, resulting in the existing interior wall panels (interior wall tiles) are generally made of bright glaze, the reflective color rendering index is generally low, so that the decorative effect is greatly restricted, and the sense of grade is low

Abstract

The invention discloses an indoor wireless communication signal transmission control method. The method comprises the following steps: (1) detecting an indoor wireless communication signal source anda receiving terminal of a building; (2) detecting indoor and outdoor transmission paths, transmission strength and wall penetration strength of wireless communication signals sent by various indoor signal sources; (3) setting an indoor coverage hot spot area for indoor wireless communication signal transmission according to requirements corresponding to a detection result; and (4) setting a composite protection plate at a specific position on the surface of the inner side of the wall body of the building to absorb or diffusely reflect redundant wireless communication signals sent by an indoorsignal source, so that the signal error rate is reduced, indoor and outdoor wireless communication signals are bidirectionally blocked, indoor information is prevented from being leaked to the outside, and outdoor signals are prevented from being transmitted to the inside. The invention further discloses a composite protection plate for implementing the method and a preparation method of the composite protection plate. According to the invention, wireless communication protection and secrecy are realized by changing a wireless communication signal transmission path or transmission intensity.

Description

technical field [0001] The invention relates to the technical field of indoor wireless communication transmission, in particular to an indoor wireless communication signal transmission control method, a composite protective plate and a preparation method thereof. Background technique [0002] With the rapid development of GPRS, GSM, WiFi, Bluetooth, NFC, ZigBee RF, RFID, NB-IOT, VLC and other wireless communication technologies and the rapid development of data communication technologies, more and more serious problems of communication and data confidentiality have been brought about. . Illegal interception of information and theft of database data often occur, and the loss of communication and data confidentiality will cause serious consequences (such as financial information, business secrets, military intelligence, etc.), so communication and data transmission control and confidentiality have become very urgent needs . [0003] Among the existing wireless communication ...
