gNodeB – stands for “Next-Generation Node B”
(gNodeB) is a critical component of the 5G wireless network architecture. In 5G World, the gNodeB is similar to BTS in 2G, NodeB in 3G, and eNodeB in 4G. gNodeB can also be deployed in a cloud-based infrastructure which supports in flexible and scalable network deployments.
Overview of gNodeB:
- Sending and receiving radio signals to and from 5G Radio & 5G User devices ( like smartphones and M2M / IOT devices )
- Have capabilities to support 5G networks higher data rates, lower latency, increased device density, and improved overall performance
- Supports high-speed data transfer for applications such as ultra-high-definition video streaming, virtual reality, and augmented reality
- Handling a large number of connected devices at the same time, allowing for efficient connectivity for IoT devices, smart cities, and industrial automation for mMTC devices
- Supports Low latency and high reliability for mission-critical applications such as autonomous vehicles, remote surgery, and industrial automation
- Uses advanced antenna technologies for maximizing Spectral efficiency , Beamforming and MIMO
Roles of gNodeB:
- Mobility management – Radio resource management , Radio signal processing
- Connection management , packet processing & baseband processing
- Security , Quality of service (QoS) & Charging
Ng-eNB (New type of radio in 4G after the 5G launch):
- Since 5G Core supports both 4G & 5G Radio , There is need to introduce new type of eNB in 4G Radio Network : Ng-eNB to work with 5G Core
- Ng-eNB allows users to connect to 5G core network using 4G radio interface (LTE RAN)
