| 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. | ||||
