5G networks aim for gigabit‑level throughput, but effectively managing wireless backhaul traffic remains a major challenge. The study analyzes wireless backhaul traffic in small‑cell and millimeter‑wave network architectures. It compares energy efficiency across these architectures and frequency bands. Numerical comparisons yield guidelines for deploying future 5G wireless backhaul networks that are economical and highly energy‑efficient.
5G networks are expected to achieve gigabit-level throughput in future cellular networks. However, it is a great challenge to treat 5G wireless backhaul traffic in an effective way. In this article, we analyze the wireless backhaul traffic in two typical network architectures adopting small cell and millimeter wave commmunication technologies. Furthermore, the energy efficiency of wireless backhaul networks is compared for different network architectures and frequency bands. Numerical comparison results provide some guidelines for deploying future 5G wireless backhaul networks in economical and highly energy-efficient ways.
