Mobile Backhaul in Cloud RAN Architecture

A new distributed architecture called Cloud Radio Access Network (C-RAN) offers a new paradigm in base stations architecture that aims to reduce the number of cell sites while increasing the base station deployment density. This new architecture breaks down the base station into a Base Unit (BU) – a digital unit that implements the MAC PHY and AAS (Antenna Array System) functionality, and the Remote Radio Head (RRH) that obtains the digital (optical) signals, converts digital signals to analog, amplifies the power, and sends the actual transmission. By making the…
