Answer 1

Cell towers are much more sensitive to all the cell phone signals than your cell phone is, they also have much more processing of the signals to clean it up and fix bad packets,etc.

When you look at old cell phones from the really early generations, they were so big because their transmit power had to be so high since there were so many less cell towers around.
