I'm not sure why anyone writing a science article would ever talk about anything being "potentially infinite". You could claim that the ability to broadcast on different frequencies gives you room for a potentially infinite number of broadcasts, arguing that frequencies are real numbers and there are an infinite number of them between any two points on the radio dial. Unfortunately, you can't simply think in terms of frequencies available, because you need a certain amount of bandwidth around each one to carry information. The more closely you pack the broadcast frequencies, the narrower the slice of bandwidth you have for each, so the more frequencies you transmit on simultaneously, the less information you can transmit on each one.
I suspect that this discovery adds another dimension, as if you took the frequency line and expanded it to a plane, but that each potential transmission "point" on the "airwave plane" would need a finite area around it in which to pack information. This new dimension may allow us to use a lot more capacity that we were previously wasting (maybe), but I'm pretty skeptical that the usable area will be "potentially infinite" except in the limited sense that the usable frequency line was already "potentially infinite".
Even so, any large increase in the effective wireless bandwidth would be cause for celebration.
