3GPP Releases Timeline Explained: 5G, 5G-Advanced & Roadmap to 6G

This article explains the 3GPP release timeline, key features of 5G, the evolution to 5G-Advanced, and what to expect toward 6G. It is written for telecom engineers, planners, and technology professionals.

What is 3GPP?

3GPP (3rd Generation Partnership Project) is the global organization responsible for developing mobile communication standards. It defines specifications for 2G, 3G,4G and 5G Technologies standards, covering radio access, core networks, security, and services.

3GPP works through releases, where each release introduces new features while maintaining backward compatibility. These releases shape how mobile networks evolve over time.

Why 3GPP Releases Matter in Telecom

Each 3GPP Release:

  • Introduces new capabilities (speed, latency, reliability)

  • Enhances network efficiency and scalability

  • Enables new use cases (IoT, automation, XR, AI-driven networks)

  • Guides vendor roadmaps and operator deployments

Understanding releases helps engineers and planners know what exists today and what is coming next.
