As you move and see the bars changing, even though the phones are designed
with a LOT of lag to keep you from seeing it, you are seeing the effects of
multipath, signals coming from many directions to your phone. When the
signals coming at you in different paths are in phase, the signal gets much
stronger. When they are out of phase, they cancel each other. The direct
signal is usually stronger so it doesn't cancel completely (unless there is
no direct signal), so you see the bars go from full to 2 to 3 to full to 1
moving only a few feet SLOWLY. If you move fast, the bar meter, purposely,
doesn't follow the fading. They don't want you to see too much, especially
if the news is bad....(c;
