Sign in to save

Also known as 4-е поколение

4G refers to the fourth generation of cellular network technology, introduced in the late 2000s and early 2010s. Compared to preceding third-generation (3G) technologies, 4G has been designed to support all-IP communications and broadband services, and eliminates circuit switching in voice telephony. It also has considerably higher data bandwidth compared to 3G, enabling a variety of data-intensive applications such as high-definition media streaming and the expansion of Internet of Things (IoT) applications.

AI overview

4G is the fourth generation of cellular network technology that emerged in the late 2000s and early 2010s, designed to deliver much faster data speeds than its predecessor 3G by using all-IP communications and eliminating older circuit-switching voice methods. It matters because the higher bandwidth enables data-intensive applications like HD video streaming and expanded Internet of Things devices that weren't practical on slower networks.
