I took a poke at the abstract of the paper, https://www.nature.com/articles/s41586-024-07759-5, and its been a few years since I have done carrier grade wireless but.....
The low-loss and broadband beamformer enables a 72-Gbps chip-to-chip wireless link over 300 mm and eight simultaneous 40-Gbps wireless links
I can't be reading this right? They got 72Gb/s over 30cm?
I would love to see where this tech goes and I realise these papers are using ideal circumstance, but I don't see this being used in a meaningful way.
Hope I am wrong though.
