Exactly. Not to mention, I doubt they use the same size chip for a tablet when they can space it out more due to the option of being able to do that.Why exactly is it easier? It's nearly the same thickness as a normal smart phone.
Because it's much wider/longer. The radios themselves aren't huge, but in a 4" device there is only so much space, so additional radios may have to be stacked. In a 10" tablet, they don't have to be stacked.
