Open RAN Training and Certification
Open RAN replaces the legacy, proprietary interfaces between the baseband unit (BBU) at the foot of the cell tower with open standards. This enables units from one vendor to interoperate with units from other vendors. Open RAN is designed to make the radio access network more cost effective and flexible. It has the potential to drastically reduce the volume of physical kit that MNOs need to deploy and operate. In an Open RAN environment, the RAN is disaggregated into three main building blocks : the radio unit (RU), the distributed unit (DU) and the centralised unit (CU). The key concept of open RAN is “opening” the protocols and interfaces between these various building blocks (radios, hardware and software) in the RAN. It has various interfaces defined as fronthaul between the RU (Radio unit) and the DU(Distributed unit), mid-hual interface between the DU and the CU (central unit) and backhaul between the CU and RU.
Course objective: This course of Open RAN covers all topics which are required to have complete understanding of this topic. It is the movement in wireless telecommunications to disaggregate hardware and software and to create open interfaces between them. It is a movement to define and build 2G, 3G, 4G and 5G RAN solutions based on general purpose , vendor neutral hardware and software defined technology. More open interfaces enables networks to make networks open in nature. They can use one supplier’s radios with another processor. The basic vision is open for all. Open RAN is an umbrella term for a group of different technologies that telecom operators hope will break vendor lock-in and lead to reduction of CAPEX and OPEX for their Radio Access Networks.
