The third generation of mobile telecommunications technology is known as 3G. It’s a step up from 2G, 2.5G, GPRS, and 2.75G EDGE networks, with quicker data transfer and improved audio quality. This network was eventually replaced by 4G and then 5G.
This network is based on a set of standards for mobile devices and mobile telecommunications services and networks that meet with the International Telecommunication Union’s International Mobile Telecommunications-2000 (IMT-2000) specifications.
Services with a minimum data transmission rate of 144 kbit/s are supported by 3G telecommunication networks.
