Most smartphones use 3G technology to make it fast enough to use the Internet and other data functions. The faster 4G network operates in many places and the speed is estimated to be as fast as 100 Mbit / s to 1 Gbit / s (gigabits / second). This will be as fast as some computer networks using Ethernet. Many smart phones released after 2010 use 4G technology including the latest version of 4G called LTE. Plan 5G
