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.

In contrast, however, most wireless service providers who offer 4G use the Long Term Evolution, or LTE, standard. The first networks in the world to provide 4G using the LTE standard were Nokia Siemens Networks and Ericsson, both located in Sweden. EE launched the first 4G-LTE service in the U.K. in 2012. 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.
