It has been widely reported that AT&T Wireless will launch the five LTE markets on Sunday September 18th but it most likely won't compare to Verizon's LTE 4G network. AT&T's desires to purchase T-Mobile largely comes from the need to gain access to the company's AWS spectrum. The additional spectrum will augment AT&T's existing AWS and 700 Mhz holdings to bolster a nationwide LTE deployment and provide the spectrum necessary to compete with Verizon's 22 Mhz LTE deployment.

In the near term AT&T's advantage comes from the ability to fall back to the HSPA+ network and its higher speeds compared to Verizon's CDMA EVDO Rev A network. Read More...
