For short-range communications such as Wi-Fi or Bluetooth, the existing higher frequencies will do just fine.

But getting more low-frequency spectrum would be great for longer-range mesh based use cases. For example, I find it quite absurd that I can't message friends a few hundred meters away (e.g. on an airplane sitting in a different row, a few aisles over in a supermarket in a basement etc.) without the both of us having an internet connection via Wi-Fi or cell signal.
