Why 2.3 & 3.5 GHz Adjacent Spectrum Works — But 800 MHz Fails | FDD vs TDD Explained

A critical question many viewers asked: If operators in 2.3 GHz and 3.5 GHz bands sit adjacent to each other, why don’t they suffer the same interference problem that Bharti faces in Rajasthan with BSNL–Tejas and Jio in the 800 MHz band? The answer lies in duplex architecture — FDD vs TDD. In this video, I explain: Why interference occurs in low-band FDD systems like 800–900 MHz How BSNL–Tejas downlink spillover floods Airtel’s 900 MHz uplink receiver Why receiver choking happens when interference is ~ -50 dBm but actual phone signal is ~ -100 dBm Why the same issue does NOT occur in 2.3 GHz and 3.5 GHz TDD bands How time-aligned transmission and network synchronisation prevent clash in TDD Why adjacent spectrum is not the problem — poor coordination and filtering is This video is a logical extension of my earlier deep dive on the Rajasthan case: 📌 Reference Video: BSNL–Tejas 800 MHz vs Airtel 900 MHz: Real Interference Story Explained    • BSNL–Tejas 800 MHz vs Airtel 900 MHz: Real...   Together, these two videos clarify: ✅ Why Bharti’s problem is architectural, not political ✅ Why TDD avoids interference even with touching spectrum ✅ Why FDD in low bands demands stricter guard bands & filtering ✅ How poor engineering choices translate into bad user experience The explanation is supported by visual animations to make complex RF behaviour simple and intuitive. ⚠️ Fair Use & Legal Disclaimer This video references publicly available government documents, spectrum charts, and company names/logos strictly for educational, analytical, and fair-use purposes.
