Okay, let’s read and find out whether we can find something that we don’t know.
There’s no paper, there is no letter, it’s a simple statement at the institute page. The way science is being communicated nowadays is frustrating.
From the statement
However, alongside the commercially available C and L-bands, we used two additional spectral bands called E-band and S-band. Such bands traditionally haven’t been required because the C- and L-bands could deliver the required capacity to meet consumer needs.
So they indeed broadened the frequency range.
They also did not say anything about limitations. They just pushed this bizarre number everywhere 🤷🏼♂️

if there is a paper you probably can’t read it because it’s published behind a pay wall, because fuck normies i guess.

You can read their previous papers
that’s cool. Unfortunately a lot of actual research is still pay walled.
