Propagation environment reproduction device, propagation environment reproduction method, and propagation environment reproduction system

Abstract

This disclosure relates to a propagation environment reproduction device that reproduces a propagation environment for verifying the communication performance and the like of an object of measurement. The device comprises: an electromagnetic anechoic chamber 10 that blocks electromagnetic waves from the outside; reconfigurable intelligent surfaces (RISs) 16, 18 installed in the electromagnetic anechoic chamber 10; an RIS control device 20 that provides control signals to the RISs 16, 18; a transmitting antenna 14 installed in the electromagnetic anechoic chamber 10; a channel emulator 22 that controls the characteristics of electromagnetic waves transmitted from the transmitting antenna 14; a receiving antenna 12 installed in the electromagnetic anechoic chamber 10 as an object of evaluation; and a control server 24 that controls the RIS control device 20 and the channel emulator 22. The RISs include a first RIS 16 which has a characteristic of changing the transmittance of electromagnetic waves in response to a control signal, and which is located between the transmitting antenna 14 and the receiving antenna 12.
