China telecom's 5G technology showed its important role in Baidu's self-driven vehicles, Volvo's smart cars and Nokia's virtual reality shooting platform at the Light of the Internet Expo, an innovation gala for Internet fans during the Second World Internet Conference.

5G technology, known as an upgraded version of current 4G technology, is expected to roll out within five years. It can enable people to download a full-length movie or 100 songs within one second.

China is already a driving force in several international efforts such as 5G technology development, said Zhao Houlin, secretary-general of the International Telecommunication Union, in an interview with China Daily.

Earlier this year, the Ministry of Industry and Information Technology said the country has started exploratory work on 5G technologies and is planning commercial tests soon.
