Typically the higher the frequency the higher the path loss through air and through obstrucitons like walls. That's why 900 MHz is preferable for long distance communications and for penetrating through buildings, whereas 2.4 GHz and 5 GHz technologies exhibit significantly less range and higher losses through walls. 60 GHz is much higher frequency, so almost no signal penetrates through walls and even in the air the losses are quite high.
