US 3G and 4G networks face off once more

Competition for the US cellular speed crown is certainly fiercer than it was last year, when Verizon's 4G LTE let it walk over the competition unimpeded. With AT&T's LTE in the running, though, have the ranks changed? No, but only just barely: as PCMag discovered in its annual countrywide testing, Verizon mostly trumped its fellow telecom giant in upload speeds and reliability. AT&T could once more claim to be best in a category with the fastest downloads, although it's counterbalanced by having a considerably smaller LTE network. For everyone outside of T-Mobile and its still very respectable HSPA+ network, it's better luck next year. We'll be most intrigued then, quite frankly -- in addition to 2013 giving us a genuinely functional Sprint LTE network, that's when we could see a blistering-fast T-Mobile LTE-Advanced produce an upset victory.
