What do you understand by 5G Functional Split? and what are the main components of the functional split in 5G? also what are the main components of Huber+Suhner’s 5G functional split?
Functional split in 5G refers to the way in which the various network functions are distributed across the different layers of the network architecture. Huber+Suhner, a leading provider of connectivity solutions, has developed a functional split for 5G that is optimized for the transport of high-speed data over fiber-optic networks.
Here are the main components of Huber+Suhner’s 5G functional split:
Split 6: This is the split between the radio access network (RAN) and the central unit (CU) of the 5G network. Split 6 is optimized for fronthaul transport and uses a high-speed, low-latency Ethernet interface.
Split 2: This is the split between the CU and the distributed unit (DU) of the 5G network. Split 2 is optimized for midhaul transport and uses a high-speed, low-latency Ethernet interface.
Split 0: This is the split between the DU and the radio unit (RU) of the 5G network. Split 0 is optimized for backhaul transport and uses a high-speed, low-latency optical interface.
Here are the main components of the functional split in 5G:
1-Radio Access Network (RAN): The RAN is responsible for connecting user equipment (UE), such as smartphones, tablets, and IoT devices, to the 5G network. It includes the radio unit (RU), which communicates with the UE over the air interface, and the distributed unit (DU), which performs signal processing and other functions.
2-Central Unit (CU): The CU is responsible for controlling and managing the RAN. It includes functions such as radio resource management, mobility management, and scheduling.
3-Core Network (CN): The CN is responsible for handling the data traffic and performing the core functions of the network, such as authentication, security, and policy management. It includes functions such as the user plane function (UPF), the session management function (SMF), and the access and mobility management function (AMF).
The functional split in 5G is designed to allow for greater flexibility and scalability in the deployment of the network. For example, by separating the RAN from the CU, operators can deploy the RAN closer to the edge of the network, while keeping the CU in a centralized location. This allows for faster response times and better overall network performance. Additionally, the functional split allows operators to optimize the network for different use cases, such as low-latency applications or high-bandwidth applications, by adjusting the distribution of network functions accordingly.
