What does at&t's network have to do with the iPhone? Just wondering seeing as this is in the iPhone section.
Essentially the iPhone is partly driving AT&T's move forward because if it's appetite for Data consumption.
The reason AT&T has trouble with it's service sometimes is the amount of cell sites and bandwidth utilized by iPhone devices, there is no other carrier with a single device that consumes 1/2 of what the iPhone's out there consume.
Verizon's network would be slow too, and the fact they can only push Voice or Data at one time limits their ability to provide feasible service to an iPhone device.
Verizon's separation of voice and data is a major reason why they don't suffer from dropped calls due to data overload, as ATT does. Many users gladly rely on a solid connection of one type, over a flaky simultaneous setup.
And since ATT is still at least 40% of iPhone world sales, what ATT wants (or allows) often drives iPhone capabilities.
Individual devices don't matter. It's the total usage picture that counts.
- Sprint and Verizon carry far more wireless data than ATT, due to laptop users.
- Verizon smartphone users consume more data individually than iPhones, probably due to less restrictions.
- ATT has said that the iPhone isn't the major cause of data congestion, it's all their new IM capable devices.
The reasons ATT has trouble, are because they didn't have the backhaul, and they didn't site their towers correctly for 3G (WCDMA because they didn't start with CDMA radio experience, unlike Verizon, and they've reportedly set up their internet network incorrectly. They're now fixing all of this.
