More than a tad. Nonetheless: Different frequencies have different propagation characteristics. At 3.5 MHz you can communicate around the world with one watt of power, while at 400 MHz you can't go more than a hundred miles with 1500 watts*.
The higher in frequency you go, the more the radio waves behave like light. 2.4 GHz passes right through wood, plaster, etc with only a little attenuation. 5 GHz is affected much more. 10 GHz is even worse in that respect.
*There are some very specific exceptions, such as tropospheric ducting, but I'm discussing 'normal' propagation here.
