In April 2022, Huawei proposed the concept of F5.5G to enhance the three existing features of F5G (eFBB, FFC, and GRE) and extend three new features: green agile optical network (GAO), real-time resilient link (RRL), and optical sensing &. In April 2022, Huawei proposed the concept of F5.5G to enhance the three existing features of F5G (eFBB, FFC, and GRE) and extend three new features: green agile optical network (GAO), real-time resilient link (RRL), and optical sensing & visualization (OSV). F5.5G will bring four major changes to the industry. First, it will help us transition fro. Over the past two decades, fixed networks have evolved from meeting just basic connectivity needs to allowing users to enjoy 4K ultra-HD video experiences. F5G standards have also taken shape as fixed network technology evolved to meet booming demand in the digital era. In 2020, the European Telecommunications Standards Institute (ETSI) officially. Given the global progress of informatization and digitalization, we are due for a new wave of transformation. Society is rapidly going networked, digital, and intelligent.
