In this video, I break down the issue using the actual Indian band plan and simple visuals: How BSNL’s 800 MHz downlink and Airtel’s 900 MHz uplink sit next to each other in frequency Why a “too-wide” Tejas 800 MHz filter can leak into Airtel’s uplink window (~890–894 MHz) Why BTS-to-BTS interference is deadly, even when phones seem to work fine The difference between compliant spectral masks vs generic / wide RF filters What this incident tells us about indigenous gear readiness and multi-operator coexistence This is a technical explainer based on public information and band allocations.
