Between 2015 and 2022, several experiments reported nonequilibrium collective vibrational behavior in proteins consistent with Fröhlich's long-discussed phonon condensation hypothesis. These studies identified prominent spectral features at 0.071, 0.096, and 0.314 THz. In parallel, wireless research toward 6G increasingly explores carrier frequencies above 100 GHz, with candidate bands approaching 0.1–0.3 THz. This frequency proximity has motivated speculation about possible biological relevance. However, frequency overlap alone is insufficient—meaningful interaction requires adequate coupling strength under realistic exposure conditions. This paper (i) summarizes the relevant experimental findings, (ii) clarifies the current state of 6G frequency proposals, (iii) provides an order-of-magnitude estimate suggesting that direct far-field coupling at guideline-level exposures is likely negligible, and (iv) proposes a concrete experimental program to definitively test whether realistic sub-THz fields can modulate reported protein collective modes. Whether the outcome is null or positive, such measurements would reduce uncertainty as sub-THz technologies mature.
