MCSM is a recently proposed novel system concept to solve the massive access problem envisioned in future communication systems like 5G and industry 4.0
systems. This work focuses on the practical verification of the theoretical gains that MCSM provides using a Hardware-In-the-Loop (HIL) measurement setup. We present results in two different scenarios: (i) a LoS lab setup and (ii) a non-LoS machine hall. In both scenarios MCSM shows promising performance in terms of the number of supported users and the achieved reliability.
