Now a day’s information and communication technology(ICT) more important in our life or our society.
In ICT Wireless communicationis an important or major element which is play more over role in our societyand in the world 1. By thewireless communication technology people in the world may easily communicate toother persons. In the wireless communication there are rapidly change with thepassage of time. In the start there is 2G wireless systems and after it in 2001its convert in the 3G system. Wireless mobile network transfer from puretelephony system to network. With the passage of time there is so advanceincrement in the wireless communication.
Demand for data services over theinternet increases so 2G and 3G technology driven. In 4G so advance technologyis used or advance radio interface is used with orthogonal frequency divisionmultiplication (OFDM) and multiple input multiple output (MIMO) also link adaptiontechnology. The data rate for the 4G wireless network is 1 GB/s 2.
Now a day’s wireless communication increasesquickly. Mobile users are increasing every year. So a new idea arise of fifthgeneration for wireless communication technology. Basically IEEE give this newidea or created this issue. In 5G network more than 100 antennas utilized forgigabit wireless traffic transmitted 3.
For 5G cellular network presented small cellnetwork. For safely coverage base stations are pleased after every 40 to 50kilometer. Physical security of radio frequency spectra allocated for cellularcommunication is more challenge. In 5G Wireless communication energy consumingis moreover or increases. This is causes of increase of CO2 emissionindirectly 3. Energy consumption of base station contributes to over seventypresent of electricity bill by cellular operation. Basically in three mainareas efforts made which are enhancement of spectrum efficiency, expensive ofspectrum, network densification. Level of complexity, coupled with reducedcontrol over application, data increase due to the dense deployment of smallcells on large scale and networks operators are facing some challenges like:Control and manage it so difficult,deploy of small cell densely is so costly.
5G network have system capacity ofone thousand (1000) times, spectral efficiency, data rate, energy efficiency isten (10) time’s and through put of average cell is twenty five (25) times 4. In this article review the study of 5Gcommunication network.
