LulzSec dumped one last load of AT&T documents on the internet, which though outdated and never meant for public consumption, does give some insight into some of the things they were at least considering -- like speed and session-based pricing for their upcoming LTE network.
But one interesting tidbit is AT&T's apparent plan to market LTE data with various speed tiers, which it's calling "Speed Based Pricing." Verizon's about to switch to tiered pricing for its data plans (3G and 4G), but that's based on total consumption, not speed. The basic idea would be pay more, and you get faster LTE speeds. Not exactly a new premise -- cable companies have been doing this for Internet access for a while now, but it'd be an interesting change in the mobile space.
You could also pay for a session, or temporary speed boost if you needed it. Again, this is something broadband providers have been doing for a while.
Of course, we probably won't get our hands on LTE until iPhone 6 in 2012, but it's still interesting to see where the industry might be by then. Any of you have an interest in speed or session based pricing, or are data caps complicated enough already?
