I am picking up 4g where I work, between Muhlhauser and port union. Seems to penetrate the concrete walls quite well. Speeds range from 1.5mbs-3mbs.... but if I roam onto Verizon 3g it's close to the same speed......
I have and complained before, when talking to them about the connection issues they look to see if any towers are down. Then say how odd that the speeds are slow.. No real help
