In the early 1990s, Australian radio astronomer John O Sullivan and his team at CSIRO were trying to detect tiny, evaporating black holes in deep space. To find these signals, they had to decode faint, scrambled radio waves that bounced through cosmic dust. The signals were heavily distorted by reverberation, making them nearly impossible to read.
While O Sullivan never found those mini black holes, his mathematical solution to unjumble bouncing radio waves proved revolutionary elsewhere. In the late 1990s, computer engineers struggled to transmit wireless signals inside offices because radio waves reflected off walls, furniture, and metallic surfaces, causing extreme interference.
O Sullivan realized his cosmic algorithm could solve this indoor reflection problem. By splitting one fast signal across multiple lower speed channels, known as orthogonal frequency division multiplexing, wireless devices could communicate cleanly through indoor clutter. This breakthrough became the core patent behind modern Wi Fi technology, powering billions of wireless devices across the globe today.
