This kind of work sounds potentially (?) important for continuing to improve network technology. Unfortunately I don't have the background to understand why it works in the slightest.

However, it reminded me of an older approach to signal filtering that I just recently learned about: the superheterodyne radio receiver. It's a simple idea that enabled us to build cheap, tunable radios. YouTube video if you're curious: https://www.youtube.com/watch?v=hz_mMLhUinw. Definitely an accessible introduction to a neat trick in signal processing!
