摘要

The ultra-dense network (UDN) has been considered as a promising candidate for future 5G network to meet the explosive data demand. To realise UDN, a reliable, gigahertz (GHz) bandwidth and cost-effective backhaul network connecting ultra-dense small-cell BSs (SBS) and macrocell BS (MBS) are pre-requisite. Millimetre wave (mmWave) spectrum can be used to obtain potential gigabit-per-second (Gbps) traffic for wireless backhaul. Moreover, mmWave can easily integrate with massive MIMO for improved link reliability. In this research work, we analyse the wireless backhaul traffic in two different scenarios (e.g., centralised and distributed) using small cell and mmWave communication. Furthermore, the energy efficiency (EE) of wireless backhaul network is compared for different network architecture and frequency bands. Numerical comparison results provide some guidelines for deploying future 5G wireless backhaul network in economical and highly energy-efficient way.
