On how to measure the interference of multiple wireless transmission systems using a well defined environment

Methods of waveguided measurements of the interference of multiple wireless transmissions are well known. In this paper a new method is shown using a well defined line-guided procedure to measure the interference between several wireless transmission systems in the same frequency range. The setup is based on wired connections in order to produce a repeatable RF channel between the DUT´s. Complex structures such as anechoic chambers are not necessary for this setup. It is possible to simulate the individual free-field-loss between each antenna as well as the signal propagation time between the wireless devices. Variations of the setup can be easily made in order to test the performance of the DUTs under various wireless channel conditions.
