Energy Efficient Millimeter Wave Backhauling in 5G Heterogeneous Networks

The tremendous rise in mobile services utilization is highly challenging for wireless telecommunication operators around the globe. The energy consumption is rapidly increasing because of condensed placement of the small cells. The energy-efficient millimeter wave (mm-wave) backhaul architecture for 5G heterogeneous cellular network (HCN) is required. By the development of mm-wave backhauling for small cells in 5G heterogeneous network (HetNet) the high frequency, high data rate, high bandwidth, and energy consumption issues of HCN can be reduced. This paper presents the technologies and architecture of mm-wave backhauling for 5G HetNet. Furthermore, the paper discusses the limitation of the mm-wave backhauling and suggested solutions for 5G HetNet.
