I just mapped some spots on between Hanley and Waters - Sheldon and Waters. I Work in that plaza @ Hanley and Waters and I notice I got 4g during the day. Inside the building I got one bar of signal and download speed suk, less than .500m. Outside the building 2 bars of signal downloading little less than 5m. Still suk, but better than .050m 3g
