I'm in Elyria, and I have great 3g, but no 4g as of yet. Also have not noticed any 4g along the lake areas. My office is in downtown Cleveland, and i get STRONG 4g in Westlake, Rocky River, North Olmstead, and PARTS of downtown Cleveland. But nothing like the map shown above.
I have taken readings in Terminal Tower, at City Hall, at the Science Center, Case Western, East 71 and Euclid, and at Cleveland Clinic.. no 4g in ANY of those places. (Though I was getting spotty 4g in my office on E71 and Euclid last week on Wednesday...musta been testing..
