With the development of advanced communication systems such as ITS-G5 (C2C, C2I), mobile, and in-car communication systems, more and more systems are operating simultaneously. To verify their reliability in a coexistence scenario, all systems have to be tested under realistic conditions. The so-called two-stage method provides a test procedure for such systems. Unfortunately, it does not consider self or inter-system interference for which the radiated two-stage method was developed. Based on this method, this contribution proposes an approach which allows to test large objects with multiple antennas/antenna-systems under realistic propagation conditions. It is realized in an over-the-air setup for wide-band applications by creating orthogonal wireless channels, a technique also known as wireless cable.
