Some of my fastest speeds on att and sprint are in the poor sides of town.... why..? Cause 99% of them are on metropcs leaving the top 4 providers traffic free which means high data speeds :-)
Now when i get the "normal" sides of town where the majority have one of the top 4 providers, then my speeds are always under 1m ...

AT&T 4G LTE
I talked with the Mobility C.O. Switching guys and they verified that LTE is indeed turned up in downtown Chicago but they couldn't verify the suburbs. I'm bringing my laptop and Momentum there tomorrow to see what I'mgetting. AT&T did say that they were turning it up as of Monday. The Mobility guys said that the switches are enabled but the traffic might still be inhibited.
Also I was in an AT&T chatroom for the Momentum. They said it won't say LTE yet; they will update the firmware. They couldn't confirm whether LTE was really turned up or not.
Eg. I'd expect 4G at Ohare, LAX, DFW before I'd expect it at somewhere like Holmby Hills/Los Altos Hills or other affluent residential areas. Many upscale residential areas are also NIMBY areas.
AT&T... your world, throttled.
OK. I'm really happy and excited because for the last few days I've been testing AT&T's HSPA+ network, and I have to say, here in NYC things are moving forward! It looks like AT&T has finally moved to flat IP network since their HSPA+ latency is actually on par with T-Mobile's!!! I'm seeing ping on speedtest.net in the high 40's averaging around 60ms!! That's magnificent, coming from 100+ ms just a few weeks ago!
That said, the backhaul is still NOT in place here, although it's advertised as "enhanced backhaul" market just not LTE. Now if 14.4mbps rate limiting is what they call "enhanced" then maybe that's just as good as we'll ever get on AT&T's HSPA+. On my Shockwave and/or unlocked Huawei AirCards, I'm seeing speeds capping at 14.4 MAX! Using a well seeded torrent I'm averaging at around 1.3MB/s peaking at just about 1.8MB/s (14.4mbps). It looks like AT&T's backhaul is not abundant, and instead of properly deploying fiber to the sites and leasing sufficient amount of backhaul, instead they're definitely applying "rate limit" to all NYC users at 14.4mbps no matter what device we're using.
Here are some fresh screenshots:

Is this actually improving AT&T's legendarily bad dropped call performance in New York as well? I know when AT&T had Root Metrics do a study for their NYC market, NYC had the worst score recorded for dropped call performance in any market since the inception of the Root studies. AT&T had closed gaps to competitors in other markets (SF being a key example where they actually finished 2nd to Verizon and ahead of T-Mobile and Sprint), but there was no such closing of the gap on the NYC front.
Any movement in that regard?
Fiber backhaul for Verizon in Southern Illinois in 2013 - about time.
For some reason I highly doubt they are running "limited backhaul" in a place like NYC especially after swapping hardware out to run flat IP, prepping for LTE, running 4 carriers as it is and wanting to add a 5th (which suggest more need for spectrum/cell sites than anything).
hitting 14.4 max looks like something other than backhaul, like traffic shaping, rate limiting, or not hitting 64qam. I believe you have already demonstrated that there is some sort of traffic shaping/rate limiting already in use and there is going to be for LTE. It could be something like limiting devices to 10 of 15 HS-DSCH codes to reserve some spectrum for "other" signalling, this ironically would limit you to around 14mbps with 64qam etc.
Also must consider how locust's fastest HSPA+ on AT&T was also 14.xx mbps in a completely different state that is a different region, market, probably backhaul provider which kinda points to being some sort of limit.
but without actual inside knowledge or the proper tools you can't really know.

iPhone 4 on AT&T:
Here is an odd test... 90% of the test it was sitting between 200-300k and then at the end spikes to 3M ....
