Liberty, IN tower and Oxford, OH Morning Sun Rd tower have both been upgraded to 4G, still no handoff.
Though, coverage along OH-177 between SR-73 and IN-227 has improved significantly. Still dropping in Fairhaven valley.
Calls on the outskirts of Oxford are garbled a bit, but not dropping. I hear this is an artifact caused by the mixmash of old 3G and new 4G upgraded towers.
