4G LTE is a high-speed wireless data technology that offers speeds of 5-12 Mbps download and 2-5 Mbps upload (up to 10 times faster than 3G data speeds). However, like any wireless data, speed is impacted by geography, distance from a cell site and traffic on the network.
4G LTE mobile broadband devices and smartphones will be backwards compatible. These devices will connect on our 2G (1XRTT), 3G (EVDO) networks when it does not register with a 4G LTE network. Some devices may have a toggle option to preserve battery life instead of actively searching for 4G LTE. LTE is a trademark of ETSI.
