The radio access network (RAN) has been in use since the start of cellular technology and has evolved through the generations of mobile communications (1G through 5G). parts of the RAN embody a base station and antennas that cowl a given region counting on their capability.

Radio Access Network Basics
In a RAN, radio sites give radio access and coordinate the management of resources across the radio sites. a tool is wirelessly connected to the core network, and also the RAN transmits its signal to numerous wireless endpoints, and also the signal travels with alternative networks’ traffic.
Two styles of RANs square measure Generic Radio Access Network (GRAN), that uses base transmission stations and controllers to manage radio links for circuit-switched and packet-switched core networks; and GSM Edge Radio Access Network (GERAN), that supports time period packet information. 2 alternative styles of RANs square measure UMTS Terrestrial Radio Access Network (UTRAN), that supports each circuit-switched and packet-switched services; and Evolved Universal Terrestrial Radio Access Network (E-UTRAN), that focuses solely on packet-switched services. E-UTRAN additionally provides high information rates and low latency.
RAN Controller
The RAN’s controller controls the nodes that square measure connected thereto. The network controller performs radio resource management, quality management, and encryption. It connects to the circuit-switched core network and also the packet-switched core network, counting on the sort of RAN.
Today’s RAN architectures — notably in digitally remodeled networks — separate the user plane from the management plane into completely different network components. during this state of affairs, the RAN controller will exchange user information messages through one software-defined networking (SDN) switch, and a second set with base stations via a second control-based interface. This separation of the management plane and information plane are going to be a necessary side of the versatile 5G RAN, because it aligns with SDN and network functions virtualization (NFV) techniques like service chaining and network slicing.
RAN Evolution
Radio access networks have old a lot of evolution since their origins, to the purpose at that today’s RANs support multiple-input, multiple-output (MIMO) antennas, giant spectrum bandwidths, multi-band carrier aggregation, so on — all of that bodes well for the 5G future.
