Ma Bell is speeding up the 4G train

AT&T, Inc. (T) has long enjoyed the fastest 3G network in most U.S. regions.  And early reports indicate that AT&T LTE -- the company's 4G solution -- is the fastest in the U.S. in the select regions where it's available.

Looking to build on its strengths, AT&T Labs President and CEO Krish Prabu announced plans yesterday to deploy advanced LTE -- a faster 4G implementation -- across the country in 2013.  Addressing an audience at the LTE North America Conference in Dallas, Texas, Mr. Prabhu described how LTE Advanced would allow the company to leverage so-called "advanced network topologies".  For the consumer, he says the end result of this faster, better-connected network will be improved capacity and coverage.

Thus far, Sprint Nextel Corp. (S) has been the only other major player to announce plans for LTE Advanced.  Sprint, which currently uses WiMAX 4G, said in an October presentation that it plans to use its 800 MHz spectrum block to install LTE Advanced by H1 2013.

It is unclear if Sprint will build this network itself or leverage its partnership with Clearwire Corp. (CLWR), a wireless infrastructure firm that counts Sprint as its biggest investor.  Separately Clearwire had promised that it could upgrade to LTE Advanced by deploying Time-Division Duplex (TDD) LTE atop of its existing WiMAX network.  It says it needs $600M USD in additional investment, though, to complete the upgrade.

Verizon Wireless, the joint venture between Verizon Communications Inc. (VZ) and Vodafone Group Plc. (LON:VOD), has not yet announced plans for LTE Advanced.  And thus far possible AT&T acquisition T-Mobile USA -- a subsidiary of Deutsche Telekom AG (ETR:DTE) -- remains without any first generation LTE solution, still relying on HSPA+ as its pseudo-4G offering.

For AT&T the company's biggest strength has long been data speeds in areas where coverage is good.  The biggest weakness, though, is that AT&T's coverage is much patchier that Verizon's.  AT&T's 4G network already badly lags behind Verizon's in coverage, despite its industry-leading speeds.  AT&T's LTE network by the end of the year will cover approximately 70 million Americans, while Verizon's LTE will cover over twice that number -- 160 million Americans.

With AT&T joining Sprint in the race to LTE Advanced (likely TDD-LTE), the question becomes whether AT&T is yet again sacrificing coverage upgrades for speed upgrades.

On Sunday AT&T flipped the switch on LTE networks in four new cities -- Athens, Georgia; Baltimore, Maryland; Boston, Massachusetts; and Washington, D.C.

Most of AT&T's network is still Edge today. Progress indeed.

Even with T-mobile, when I travel into my old Beverly neighborhood in Chicago, all I get is Edge. Coincidentally, my parents, who have AT&T, get 3G, but terrible voice reception, so bad they've considered buying a microcell for their home. But the 3G works fine!

Where are you getting that info? I'm a Cell Network contractor that does a descent amount of work for AT&T, I travel all over the east coast and have never once been to a site that was GSM/EDGE only. That includes sites out in the middle of nowhere. TMO does that do keep costs down where they don't have many subscribers just to keep travelers up and running, but AT&T does not.
