As AI accelerators pack more power into less space, a silent electromagnetic war is breaking out inside the rack.
Walk into a modern AI data centre and the first thing you notice is the sound, a relentless wall of cooling fans fighting to keep pace with ever-rising heat loads. The second thing you notice, if you are an RF engineer, is something operators seldom discuss publicly: the electromagnetic noise floor is exceptionally high and climbing.
Driven by the insatiable demands of large language models and computer vision workloads, the rapid densification of AI compute has created a challenge that spans power electronics, RF engineering, and computer architecture. Yet responsibility remains divided across these disciplines, slowing efforts to tackle the issue at the speed it demands.
