The answer is actually quite simple
When you use a wireless network to carry “wireline-like” home broadband traffic, capacity gets stressed very quickly and the network investment required becomes massive.
A typical mobile user might consume 20–30 GB/month. But a regular FWA/home broadband user can easily consume 400 GB to 1 TB+ per month (sometimes much more if there’s 4K streaming + multiple screens). That’s 20x–100x higher usage.Now add one more thing: both Jio AirFiber and Airtel Xstream AirFiber are pushing “TV / OTT on AirFiber” as well.
Video is the biggest traffic driver. If they allow 3.3 TB at scale, that can choke the cell capacity in many areas—especially where spectrum is limited.That’s why they reduced the fair-use limit to ~1 TB: it’s basically a network-protection cap, not a “marketing” cap.
Why is this harder than fiber?FWA runs largely on mid-band 5G (3.5 GHz) (Airtel mainly, Jio partly) and in Jio’s case also some UBR / capacity sharing.Mid-band spectrum is limited, and the same sector has to serve many users.Broadband ARPU is only ~2–3x mobile ARPU, but data usage is 20–100x. The math doesn’t work long-term unless you cap heavy users.
Why does Jio sell top-ups but Airtel doesn’t?Because top-ups can push more heavy usage onto an already constrained radio network. Some operators prefer a hard cap to avoid quality complaints and unpredictable congestion.
My broader view: FWA is useful as a gap-filler where fiber is not available, but at scale it will face quality and congestion issues unless operators put serious spectrum into it. They could use 26 GHz, but propagation is difficult, requires dense sites, and is not easy/cheap to deploy everywhere.So the cap reduction is basically a sign of the underlying reality: wireless cannot behave like unlimited fiber without trade-offs.
