Verizon announced yesterday that it's serving 75 percent of the US population with LTE, but AT&T is diligently expanding as well: the company just announced that it's bringing LTE to Fayetteville, Springdale, Rogers, and Bentonville, Arkansas, as well as Waco, Texas. That brings AT&T's total markets served to 53 compared to Verizon's 370 — and even though Verizon had a headstart in its 4G rollout, it's important for AT&T that the gap doesn't widen. While AT&T's latest expansion into Texas and Northwest Arkansas is sure to please customers in those areas, the company still has a long way to go before it completes its LTE rollout scheduled for the end of 2013.
