Long Term Evolution, or LTE, is a next-generation wireless broadband network. Marketed as 4G LTE, it is an all-IP based network, and much faster than its predecessors with download speeds of up to 100 Megabits/second. Much higher network capacity and speeds mean better quality voice and data services, as well as high-definition video capabilities.
According to the Global mobile Suppliers Association (GSA), 455 million people today have access to commercial LTE networks. 1,113 mobile network operators have launched commercial LTE services across 94 different countries. Amongst the LTE operators are Verizon Wireless, AT&T, T-Mobile and MetroPCS. See the full list at http://lteworld.org/operator.
