Purchased the phone last night, have dropped two phone calls from a stationary location out of the five calls I've made today. There seems to be no rhyme or reason to the problem. As I'm writing this, I'm staring out the window at AT&T's tower a little more than a half mile away. I work from home and I work from the second floor in a house that's above streets between it and the tower. I'm in 3G coverage and here's the grab of my coverage location: Does AT&T hire engineers to map coverage areas? If so, can I get them out to my location to investigate? The image you're looking at covers roughly a half mile from top to bottom... that much variation is ridiculous for negligible difference in elevation and terrain. Upstairs I usually get 5 bars but it drops to 2 out of the blue and the call fails (and it SHOULDN'T fail with 2 bars). Downstairs on the main level I'm lucky to get one. Basement? Forget about it. Is there the possibility of wireless internet interference? I'm on channel 1, B&G.
