Abstract/Summary
This project investigates the signal strength of Wi-Fi signals through different wall assemblies under the new Wi-Fi 6E standard. The project focuses on measuring the signal strength (-dBm) at three distinct frequencies, 6 GHz, 5 GHz, and 2.4 GHz. The 2.4 GHz and 5 GHz frequencies serve as a baseline for comparison with the emerging 6E standard. Wi-Fi 6E offers much higher speeds at the cost of high signal attenuation. The primary objective is to analyze how different construction materials impact Wi-Fi signal strength and to provide comprehensive data on wall assembly attenuation. Wi-Fi 6E signals experience significantly greater attenuation than the more commonly used 2.4 GHz and 5 GHz frequencies. On average, Wi-Fi 6E experiences 62.3% more signal loss compared to 2.4 GHz, and 43.8% more signal loss than 5 GHz. This increased loss necessitates more careful architectural design in order to optimize Wi-Fi performance. Wall assemblies must be strategically designed to limit signal degradation which requires thoughtful consideration of a variety of factors. These factors include rebar spacing, type of insulation, type of materials, and the presence of metal or metal foils. Understanding these factors is crucial for developing construction practices that support the next generation of Wi-Fi connectivity.
