Based on the International Telecommunications Union standards, the 3G network is the third generation of mobile networking and telecommunications. It features a wider range of services and advances network capacity over the previous 2G network. The 3G network also increases the rate of information transfer known as spectral efficiency. Telephony has received a wider area and more range, while video and broadband wireless data transfers have also been positively affected. These criteria are identified as the IMT-2000 standard.
A 3G network provides for download speeds of 14.4 megabits per second and upload speeds of 5.8 megabits per second. The minimum speed for a stationary user is 2 megabits per second. A user in a moving vehicle can expect 348 kilobits per second.
