I wouldn't always trust what the signal shows, as mine shows bad signal but the call quality is perfect. I have never been able to make calls in my living room but with my htc its perfect.
If you have a bad signal and its affecting calls then thats not good, but I wouldn't always trust what a few graphical bars show.
