I tried to do a bit of mapping in Ferndale but had a hard time holding an LTE signal. The 9 Mile and Hilton site is definitely not up, but the 696/75 one seems to be (although I drove right next to it on the 75N to 696W ramp and stayed on 3G). My LTE drops as soon as I go south of 9 Mile on the 75 service drive...the tower is only a mile away, is LTE range really that limited?
