Abstract
A method with which the reception sensitivity of a communication device can be measured accurately and with satisfactory reproducibility and a method with which the effect of noise control performed upon a communication device can be accurately evaluated. A first communication device in a nonreflective environment in an anechoic chamber wirelessly receives a test signal transmitted from a pseudo base station through an attached antenna thereof at the same time when a second communication device near the first communication device receives the test signal through a signal line. The first communication device is simultaneously subjected to the interference of noise generated by the second communication device at the attached antenna. Thus, the noise is made to interfere with the attached antenna of the first communication device without disassembling the first communication device and moving the first communication device in the nonreflective environment.
