Challenges of 5G Network and Technologies Used to Tackle the Problems

Abstract

In the future generation of network, data traffic in cellular network increasing rapidly. With the explosive growth of mobile internet application, mobile users are also increased. The prime objective or demands that need to be addressed are increased capacity, improved data rate, decreased latency, and better quality of service then 4G. This paper presents some key technologies used in 5 th generation (5G) network which are helpful to meet the demands of users. In this we focus on the Millimeter-wave and Massive multiple-input multiple-output (M-MIMO) technology which helps to increase the data rate (in Gbps). Along with this device-to-device (D2D) communication, densification of network, machine-to-machine communication are the technologies which are very useful to deal with the challenges like spectral efficiency, end-to-end latency and number of connected devices. At last we will see the development of 5G around the world. KEYWORD: Massive multiple input multiple output [MIMO], small cells, milimeter wave [mmwave], ultra-densification, machine-to-machine.
