I work in a 36 story high rise office building in Los Angeles. On my AT&T iPhone 4 (or all of them for that matter) I would have to finish my call before getting in the elevator. On my new Verizon iPhone 4, I get 4 bars all the way up! This makes me very happy! I know, data speeds are slower. But so far, I haven't noticed a difference. Not so sure data speeds on AT&T were any faster in my area cause Verizon still seems to be the same for me.
Maybe it's because one operator has booster stations in your building? I have this same issue. o2 UK have full reception everywhere in my 42 floor building but Vodafone don't. This is due to o2 having booster stations on each floor/elevator.
Could be that there is a booster. Although my entire company (Universal Music Group) are on either AT&T or T-Mobile and neither work in the building. You'd think that since Universal is the majority of the building, they'd add more boosters. All I care about it my personal phone working though. Don't care much about the work phone. LOL
Don't tell JD914. He'll deny that a) you lose any AT&T signal inside the elevator and b) refute the fact that you get VZW signal in the elevator instead.
No booster needed. The elevator scenario is common in some of the larger cities, where Verizon has always had a lot of building-penetrating 800MHz band coverage and AT&T did not. However, in the past year, AT&T has started to add 850MHz signals in places like New York, and as a result actually had network overloads due to so many more people getting a usable signal inside buildings.
It really depends on location and/or actually buildings. Some elevators I lose ATT signal while Verizon craps out, and vice versa. Same thing with basements.
Great! emails sent and received, websites opened, etc. I couldn't be happier. So glad I switched. Also, did a little test with a co-worked who has her AT&T iPhone (I sold mine so couldn't do the test). We both loaded the same webpage at the same time, and they both loaded just as fast! Pretty much exactly the same, and my images loaded about a fraction of a second faster. So I'm not missing AT&T for voice OR data.
There are some places you really don't want a signal... in my early cellphone days in my favorite bar you could get a signal if you sat to the left of the taps, but to the right was a dead zone... that was great!!
