Hi//
I have a relatively new iPhone 5 (CDMA version) running on T Mobile's network. Generally very happy with it. When I'm solidly in a 3G cell's coverage the bandwidth is very good (say 6 megs down and 1.5 megs up). But here's the rub. Should also mention that I've switched to reading dB rather than 'bars' for signal strength. This comes from the 'Field Test' routine. (*3001#12345#* Hold down the power key and when the power off slider shows up hold down the Home button until it exits Field Test. Your default signal strength is now in dB.)
I can be sitting in a cell that shows -75dB and 3G (basically on top of the base station) and have the reading switch from 3G to E (EDGE) with exactly the same signal strength. EDGE is very ratty. Does anyone know what's going on here??
o Will the iPhone automatically switch to the technology that appears to have the higher signal and select EDGE over 3G? Does it prefer 2G over 3G? Could this be a firmware issue?
o Could this be a hardware problem? Any thoughts?
o My wife has an identical iPhone on the same network. I can place them side by side and see -75dB on one and -130dB on the other. This is a huge difference. Has anyone else experienced this?
I'd like to know if there's a way to 'tell' the iPhone to only connect to 3G, or at least to prefer 3G until the signal strength drops below a certain level. Then, if I'm in a cell with 3G I'll be able to use it. Personally I'd rather have 3G at -100dB than EDGE at -75dB.
Thanks,
Bob
