To experimentally evaluate the physical-layer performance and propagation characteristics of private sub-6 GHz 5G New Radio systems across sparse and dense indoor industrial settings.
Conducted over-the-air error vector magnitude (EVM) and signal-to-noise ratio (SNR) measurements across diverse modulation and coding schemes, channel bandwidths, and numerologies.
Performed channel sounding to quantify root mean square (RMS) delay spread using both omnidirectional and directional antenna setups at the transmitter and receiver.
Dense industrial settings exhibited higher RMS delay spreads than sparse environments due to severe multipath scattering, requiring higher SNR thresholds to satisfy EVM limits.
Directional antenna configurations at both transmitter and receiver mitigated RMS delay spread and inter-symbol interference, enabling high-order modulations (64 QAM and 256 QAM) with increased bandwidth efficiency and reduced latency.
Lower bandwidths and subcarrier spacings produced superior transmission quality, yielding reduced EVM and bit error rates in dense multipath environments.
