This is total BS. the reason 2.4Ghz and 5Ghz are different is becuase there is a lot of devices that use the 2.4 Ghz wavelenght like bluetooth, microwaves and even your cordless home phone. The 5Ghz is less used that is why it is less conjested. The other fact that is true is that 5Ghz has a hard time penetrating through walls and has a lower range than compared to 2.4Ghz. You can say that the 850Mhz used by webe will be better for indoors as it can penetrate throught walls and concrete better then the higher 2.6Ghz bandwidth used by Yes.
