4G technology is used to provide high-speed Internet access for mobile devices such as smartphones, tablets and properly configured laptops. The first commercial 4G network was deployed in South Korea in 2007. Unlike most current 4G networks, the South Korean provider used the Mobile WiMax standard. Sprint's 4G network, the first to be launched in the United States, used a similar standard.

China Mobile offers a tweaked version of the standard that is known as TD-LTE. Because LTE is offered on different frequencies, devices designed to be used on a 4G network in one country may fail to work on 4G networks in another country.Learn more about Mobile
