Description:: Despite the well-publicized problems in New York and San Francisco, AT&T seems to have the superior network nationwide.

And the iPhone itself may not be so great after all. Its design is contributing to performance problems.

Meh. Gruber has a good post explaining the many major flaws in this poor attempt to defend AT&T's lousy service.

And the iPhone itself may not be so great after all. Its design is contributing to performance problems.

Roger Entner, senior vice president for telecommunications research at Nielsen, said the iPhone’s “air interface,” the electronics in the phone that connect it to the cell towers, had shortcomings that “affect both voice and data.” He said that in the eyes of the consumer, “the iPhone has the nimbus of infallibility, ergo, it’s AT&T’s fault.” AT&T does not publicly defend itself because it will not criticize Apple under any circumstances, he said.

It appears there is a firmware/hardware issue with Apple's cell interface that needs a serious upgrade and optimization. If Apple were to both fix it substantially, and let it slip the newest handsets are "200% better", there might be a wave of upgrades and they can send all the older handsets to China. :D

From Gruber's post:
If it’s the iPhone’s fault, not AT&T’s, why aren’t iPhone users around the world having the same problems as those here in the U.S.?
So much for the iPhone needing an upgrade.

You'd need to compare the details between the phones and equipment though, before accepting that statement as correct.

For example, the carriers may not be using identical standards and equipment (i.e. UTMS vs. GSM's EDGE for 3G service). As the iPhone is exclusively AT&T in the US, it would mean comparing it to other nations's systems. It could even come down to specific frequency bands. Now if the equipment is absolutely identical (not likely though), then yes, it's on AT&T's implementation.

Read the rest of his post. There are other factors which make it highly unlikely that the problem doesn't rest with AT&T. Here's one: An iPhone problem should not just show up in congested areas (like NYC) while rural parts of the country are rarely affected.

But what are you referring to?
Voice, data, or both, and where?

Data and voice are tied, and in places like NYC and San Francisco, there's a need to update the system. Instead, they're likely to go with a graduated data plan, to reduce usage, and let them string out the upgrade process they've ignored implementing for years.

But I'd like to see how it's affecting rural areas.

EDGE is not 3G for starters, it's a 2G technology.

GSM and UTMS/HSDPA are global standards. O2 in the UK uses the same standards. Yes the frequencies are different, but you would think the iPhone would be optimised for it's home country (US). O2 HAD issues, but got round them.

The problem is AT&T, it's kinda proven that some areas, Seattle for example, have very little trouble with the iPhone and AT&T and others, San Francisco and NYC, have appauling problems. The equipment would be the same, the phone will be the same. The only difference is which cities are at capacity on data...

The International Mobile Telecommunications-2000 (IMT-2000) <aka 3G> includes GSM EDGE, UMTS, CDMA2000, DECT and WiMAX. It defines the band as (14.0 Mbit/s down and 5.8 Mbit/s up with HSPA+).

Unless you're getting into the differentiation of GSM(2.75G) vs. UTMS (3G) reported by most GSM/UMTS phones.

You'd be surprised at the differences in equipment from one area to another within AT&T's system.

Part of it has to do with how the infrastructure was originally created = different companies that have been bought up/merged over the years in AT&T's wireless division. Another part is to do with zones: A, B and C zones = update priority & interval. I've worked with AT&T's wireless division.

It's the same in the ISP/voice exchanges as well. Lack of funding for equipment updates doesn't help either (not enough profits re-invested back into their infrastructure, and the mergers didn't help matters, as it put much of it on hold - AT&T/Bellsouth/SBC fish-eat-fish mess of the recent past). It's a bit more complicated than that, but its the basis of it IMO.

No one used mobile Internet extensively before the iPhone came out. AT&T's network is not able to handle the massive amounts of data iPhone users pull down. They need to upgrade their infrastructure.

To be fair to AT&T, all indications are that Verizon's network would have failed too. Verizon looks good only because they don't have phones that many people actually like to use, so their network isn't congested.
