Do higher or lower frequency travel through object easier (ie walls, mountains, etc)? For example 2.4g is able to travel further than 5g with obstacles but X-rays appear to have a better penetration than 5g (ie 5g has trouble penetrating paper but X-ray can do it with ease). I've also noticed in personal experience that shorter antennas also work better in hills (which from my understanding smaller antennas use higher frequencies).
