In cloud-based RAN (C-RAN), all the signal processing were transferred from the local or small cell base stations (i.e. Distributed D-RAN) to a centralized center to simplify the network management and enhance the computation capabilities. But again, the centralized computation of C-RAN is distributed across the continuum from the cloud to the network edge in so called Fog-based RAN (F-RAN), i.e. the situation is again returned to the D-RAN.
So, I am confusing about this situation, if there is any clarification from anyone, he is very welcomed.
Dear Luay
Thanks a lot for your answer. But the confusion is still unsolved, i want to know the difference between the Fog-RAN and the traditional distributed RAN.

Dear Himadri
Thanks a lot for your answer. I have already read this paper and i still confused the difference between Fog based RAN, as an E2E distributed computed architecture, and the traditional distributed RAN of LTE-advanced and LTE-Advanced pro.
