Radio Is Hard: Wireless Communication Technologies and the Challenges They Fight

Deep End Era. Engineering with Sankalp · Oct 29, 2026 · 1h 16m

Every match day, three hours of perfect radio coverage at an Abu Dhabi stadium collapse the moment the gates open. The previous integrator blamed a phantom jammer. Owen Maguire blames physics: unlicensed spectrum shared with 45,000 phones, antennas at head height behind a wall of bodies, fading, hidden nodes and weak uplinks.
