As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the number of RRH’s continued to rise drastically with 4G densification projects over the recent years. Part 2 focuses on best practices for fiber deployment. We will check into the next protocol layer, Common Public Radio Interface (CPRI), in part 3.
