SCN Myth Exposed: Why One Satellite Can’t Serve Jio, Airtel & Vi Together

In my previous video, I explained why TRAI’s satellite consultation is not really about spectrum — but about control.

In this follow-up, I go deeper into the technical reality:

👉 Can one satellite actually serve all telecom operators in India?
👉 Can it transmit across multiple IMT bands like 700 MHz, 900 MHz, 1800 MHz simultaneously?

The answer is far more complex — and largely impractical.

Why policy direction matters

13:23 – Final Takeaway
Satellite constraints + spectrum fragmentation

13:36 – Closing Insight
Why the SCN model struggles in real-world deployment

💡 Key Insight

One satellite cannot efficiently support all telecom operators across multiple spectrum bands.

👉 Fragmented spectrum + satellite constraints = Multiple SCN paths
