Hello Telecom Engineers
If you’re diving into 5G or Open RAN, one of the most important things to understand is how RAN Architecture have evolved and why that matters for performance, flexibility, and cost.
I just wrapped up a deep article walking through the complete transition from:
➮ D-RAN ➮ C-RAN ➮ vRAN ➮ Cloud-RAN
We often hear buzzwords like Split Option 7.2x, eCPRI, or Cloud-native RAN but in this article I broke them down step-by-step, explaining:
- How RU, DU, and CU work together
- The role of eCPRI in enabling Low PHY splits
- How operators deploy real Open RAN in practice
And to keep it grounded, I included real-world case studies of how global leaders are doing it today:
Rakuten ➜ Full Cloud-RAN, Dish ➜ Cloud-native vRAN running on AWS
& Orange ➜ vRAN/Cloud-RAN
Whether you’re optimizing networks or planning future 5G rollouts, understanding these architecture shifts is a must.
Check out the full article. It’s designed for engineers and students alike.
That’s it
