The good news is that the effective range difference between 6 GHz and 5 GHz is not as significant as the difference between 5 GHz and 2.4 GHz . On average, a 6 GHz signal attenuates about 2 dB more than a 5 GHz signal in the first meter. Of course, the 6 GHz band is big, so it does depend on what channel is being used.
