to get the better bandwidth from the newer generation signals (2g to 3g, 3g to 4g, etc) you end up needing a stronger signal, which often results in the need to be closer to the tower, which can make the holes in the coverage see a little bigger.

At my house, my ATT coverage is poor. My old phone got 1-2 bars of signal strength. My new phone started off with the same strength of signal. However, one of the quarterly android OS updates resulted in a 1-bar increase in signal strength. For me, the signal strength at home does not really matter since my phone connects to the wifi router and the phone has wifi-calling enabled.
