Ergodic Capacity Estimation for 6G Millimeter Wave Smart Metering System in the Presence of Nakagami Fading Channel

Recently, the deployment of 60 GHz technology in smart cities has become one of main ‎research ‎topics. This paper aims to investigate the connectivity of multiple smart meters ‎within a 60 GHz ‎deployment framework, focusing on Ergodic Capacity (EC) as the ‎primary performance metric. ‎Monte Carlo simulations will be employed to analyze the ‎significant influence of spatial distribution ‎on system performance, accounting for ‎factors such as Nakagami-m fading, shadowing, and path ‎loss. To address mm-Wave ‎communication blockages, a Poisson Point Process was used to model indoor obstacles, ‎improving simulation accuracy. Mitigation strategies, such as multiple receive antennas ‎and maximum ratio combining (MRC), enhance signal reception and robustness. The ‎analysis shows normalized EC (ε) stabilizes after 100 trials, indicating reliability. ‎Additionally, ‎the paper ‎revealed a trade-off between the number of interfering smart ‎meters (K) and per-meter capacity, with capacity decreasing as more meters connect ‎due to increased interference and reduced bandwidth. The results highlighted the ‎superior ‎performance of 802.11ad (WiGig at 60 GHz), supporting approximately 400 ‎devices at a lower SNR ‎‎(16 dB) compared to other technologies. This analysis also ‎reveals an asymptotic relationship ‎between the number of interfering smart meters (K) ‎and SNR, providing valuable insights for ‎deployment planning and optimization. ‎
