Cloud Radio Access Network for Next Generation Mobile Networks; practical implementation benefits

Today, the amount of data on mobile networks and the customers' demands have been significantly increased. With the advent of the new 5G mobile technology, data is expected to increase even more exponentially. In order to fulfill users' requirements, Operators are moving towards cloud-native technologies and open network architectures. Specifically, operators worldwide are implementing Cloud-based Radio Access Network (C-RAN) with support for 5G technology. 5G deployment requires more computing power than 4G. Therefore, there is a need to move to C-RAN to secure highcapacity solutions.First, we will perform a detailed survey of the latest literature related to cloud-based Next Generation 5G networks regarding bandwidth utilization, power consumption, Quality of Service (QoS), resource allocation, spectrum efficiency, transmission delay, capital, and operational expenditures. In addition, we will identify the main challenges and the benefits of implementing CRAN. To analyze power consumption for Base Stations, we will use it as a case study of TK (Telecom of Kosovo). The final aim is to give essential recommendations regarding the benefits of CRAN and Virtualized C-RAN in power consumption compared to traditional RAN implemented in TK.
