The asymmetry between mobile and cell tower is important. The tower has lots of good antennas and more power. I'm interested in LTE Direct but no one has implemented that in a phone. LTE Direct has range of 1mi which is the range of most low-power systems. Ham radio gets longer range with higher power and better antennas. But only to the horizon with most people. Ham radio still depends on repeaters on high points.
