There is no definitive answer to this question as it largely depends on the definition of “largest.” For example, if measuring by geographical coverage, then Verizon would likely have the largest LTE network in the United States. However, if measuring by number of subscribers, then AT&T would have the largest LTE network in the United States. And if measuring by total data traffic carried on the network, then once again Verizon would likely have the largest LTE network in the United States. So it really depends on how you define “largest.”
