Thanks for the link! I've looked briefly at LTE internet service but hadn't seriously considered it because I'm just on the edge of decent cell service. While my phone usually displays 1-2 bars, it's not even enough to make voice calls. I think due to the topography in the area, my phone can receive signal from the tower but isn't powerful enough to transmit back. It looks like UbiFi also sells 4G signal boosters and external antennas, and that might just do the trick.
