The Third Generation of Wireless Mobile Telecommunications Technology (3G)

International Telecommunication Union (ITU)
Since the 1980s

The third generation of wireless mobile telecommunications technology was the result of research and development work carried out by the International Telecommunication Union (ITU) in the early 1980s. The first 3G network was introduced in 1998 in Japan by NTT DoCoMo, and its full commercialization and application took place in the 2000s after complying with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union.

3G networks’ communication spectrum was allocated between 400 MHz to 3 GHz and the information transfer rate is of at least 0.2 Mbit/s. In terms of communication forms, 1G technology only supported basic phone calls and this term was never widely used until 2G was available; 2G technology supported message texting on the basis of the former generation; and 3G allowed communications in multimedia including image, sound, and video. Compared with the 4G network with much higher data transfer speed prevalent globally nowadays and 5G network that’s designed for much smarter life, the 3G network is a giant technological leap because since its invention, wireless internet became available and people turn to instant video communications and real-time updates of information. As 3G opened the gate to web browsing, email, uploading and downloading on mobile phones, “mini personal computers”—smartphones emerged with a variety of applications alternating our everyday life.

With the assistance of the wireless network and smartphone, social media websites and applications thrived, performing as a sophisticated platform for communication, acquiring information, participating in the public sphere, advertising, etc., instead of a single service. Ordinary netizens are able to post blogs, comment on other posts, and share links on social media platforms anytime and anywhere; benefited from the convenience of telecommunication technology, they increasingly express themselves online and have their voices to be heard. For traditional media institutions, news’ immediacy is no more a problem as reporters and editors can accomplish their work remotely via PCs and smartphones.
