5G NR (High Speed & Optical Cable at the Base Station)
In conventional RAN (Radio Access Network), the base-band unit (BBU) is located near the base stations. Large numbers of base-band units are required to be deployed. The C-RAN – Cloud (Centralized) Radio Access Network is a technology developed during the 4G LTE networks. In C-RAN, the base-band units (BBU) are located at the centralized processing station and connected to the Antenna using RF cabling.
With the latest 5G, NR (New Radio) BTS (Base Station) is referred to as “gNB” and can be divided into two physical entities named CU (Centralized Unit) and DU (Distributed Unit). CU provides support for the higher layers of the protocol stack such as SDAP, PDCP, and RRC; while the DU provides support for the lower layers of the protocol stack such as RLC, MAC, and physical layer. The RDU is connected to the BTS or gNB station using fiber optic cables.
