Approaching to Mobile 5G Communications

Mobile ecosystem contributes to gross domestic product (GDP). GDP contribution to the economy can be evaluated by the generated value added. Since value added and subscribers growth of mobile operators is decreasing in the world year-on-year from 2012, they have sensed that ought to immigrate to a new 5G generation network. 5G technology is appearing in 2020 and owns better properties than the previous generations e.g., LTE-A. Sole properties in 5G make bit rate 1000 fold and connections to 10 fold rather than 2010 and reduce the delay below 1 ms. This technology, in addition, is multiband/multimode/multilayer system, macrocell/microcell/picocell/femtocell hierarchical system and include GSM/UMTS/LTE/WiFi technologies. Besides, 5G uses distributed antenna systems (DAS) and massive MIMO. To access 5G technology, some fundamental and applied projects should be performed.
