A Review of Futuristic Technology: Cloud RAN (C- RAN) Technologies

According to the report of CISCO study, traffic on the net due to mobile data increased rapidly and it will be nearly 11 times between 2013 and 2018. This rapidly increased traffic demands a high bandwidth carrier to increase the network capacity. The demand of 
increased network capacity rises when the world moves to 4G and onward generations. Limited amount of spectrum efficiency improved by using Wi-Fi offloads, 4G and so on. Frequency reuse play important role to improve the network capacity. The frequency reuse with the help of small cells improves capacity up to 1600x. The use of small cells makes important benefits to macro network. Suppose if we place four small cells within one macro, it delivers data 50 percentage of offload and also improves macro network performance by 315 percentages. Now to keep in mind C-RAN play important role to increases the network capacity, I write this article that will beneficiary for those who want to make research area in this field, to spread awareness among youth related to futuristic technologies.
