Abstract

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. ‎
