Review of Heterogeneous Wireless Fusion in Mobile 5G Networks: Benefits and Challenges

The 5th generation wireless network has become popular in recent days, the system could provide higher transmission speed, lower latency, enhanced spectrum efficiency and energy efficiency. However, the improvements are mainly focused on mobile base stations such as large scale MIMO, full duplex, etc. The resources of integrated multi-functional mobile terminals are wasted. In this work, we discuss the fusion technology in 5G wireless networks, to make full utilization of multi-functional terminals, the fusion of 5G, Wi-Fi, ZigBee, Bluetooth will greatly increase the transmission speed and reduce the latency, both benefits and challenges are summarized. In heterogeneous architecture, simulation results indicate that the fusion of mobile terminals could increase system capacity and reduce transmission latency significantly.
