Abstract

This work investigates the adaptation of Centralized Radio Access Network (CRAN) concepts from mobile networks to Wi-Fi, aiming to extend Fiber-to-the-Home (FTTH) to Fiber-to-the-Room (FTTR) in a cost-effective and efficient way. This involves splitting the Wi-Fi access point into separate radio and processing components which are connected via an Ethernet-based Fronthaul (FH). A key challenge in this setup is the introduction of a FH-delay between the radio and processing components, which can potentially disrupt essential Wi-Fi functions, particularly channel access. Through simulations and experiments, I aim to analyze the specific effects of this FH-delay on system performance, to estimate and reduce the FH-delay, and to develop a solution that addresses the issues caused by the setup. The results demonstrate that the FH-delay significantly impairs system performance. Nevertheless, the FH-delay can be minimized by optimizing the frame size over the Ethernet-based FH. Furthermore, my proposed WCRAN protocol provides a potential solution to the challenges faced in implementing CRAN-like Wi-Fi systems for FTTR. Thus, while standard Wi-Fi cannot directly support the CRAN architecture, the modifications introduced in the WCRAN protocol provide a promising pathway to leverage the benefits of this architectural approach.
