Sub-6 GHz Channel Modelling and Evaluation in Indoor Industrial Environments

This paper presents sub-6 GHz channel measurements using a directional antenna at the transmitter and or omnidirectional receiver 4.145 in sparse dense industrial environments for line-of-sight scenario. Furthermore, first measured over-the-air error vector magnitude (EVM) results depending on different 5G new radio modulation coding schemes (MCSs of16 QAM, 64 QAM 256 QAM) are provided. From measurement campaigns, path loss exponents (PLE) an environment 1.24/1.39 1.35/1.5, respectively. PLE lower than theoretical free space of 2, indicating that indoor have rich multipaths. The power delay profiles show maximum root mean square (RMS) spreads 11 ns with 34 environment. However, RMS significantly increased: range from 226 to 282 configuration. EVM increase coverage enable higher MCS modes be used reliable data transmission, both is required. large-scale models, multipath time dispersion characteristics provide insight into deployments networks operating frequency bands environments.
