What is the Architecture of 5G?

5G is a technology that allows for increased speed and bandwidth on existing cellular networks. This is due to the use of high-frequency radio waves that are more efficient at transmitting information than traditional lower bands. These higher frequencies are also known as millimeter waves.

The technology is designed to support a wide range of applications, such as robotics in manufacturing and agriculture, smart utilities and autonomous vehicles. In addition, it can be used in healthcare to allow doctors to control medical robots from anywhere in the world.


The 5g core network architecture technology uses a different network architecture than 2G, 3G and 4G. It consists of multiple layers, each layer supporting different functions and standards.

NFV (Network Function Virtualization): Instead of implementing the network in a traditional way, the core architecture is software-driven. It supports stateless network functions by decoupling compute and storage at the edge and core.

UDM (Unified Data Management) & UDR (User Data Repository): Similar to Home Subscriber Server in LTE, the 5G cloud-native UDM is responsible for authentication, granting access to the network depending on user subscription and retrieving user credentials.

Slicing: The 5G architecture will be able to’slice‘ a physical network into multiple virtual networks, allowing operators to deliver the right slice capacity to each user or device. This will help to manage network traffic and ensure that bandwidth is not over-used.

As a result, 5G can be used in a wide range of different ways and will enable the creation of entirely new markets. It will help to connect street lights with smart cities, allow EMTs and fire fighters to do more at accident scenes, and help farmers keep track of their crops and livestock efficiently.
