I am fortunate enough that I have exellent big red 3G coverage in my home. Even full bars roughly 90% of the time in my basement. I have yet to even use my droids wifi because big reds 3G has been so stellar. I also noticed that whenever I make an actual phone call, the signal strength sinks down to about 2 bars (sometimes 3). I am assuming this is because my 1x voice coverage isn't as good as the EVDO data coverage. my question is, what is the technical reason for this? is it because Verizons voice coverage operates at a higher fequency that isnt as good at building penetration? Are there specific towers just for voice and vice versa? Thanks in advance for any responses!
