Mobile networks are classified by generation. The first generation of mobile telephones (1G) only supported calls. With 2G, it became possible to send SMS and MMS. The arrival of 3G at the start of the 2000s enabled high speed transmission and so provided access to the Web, giving birth to new types of mobile usage.
Today, 4G increases the speed by a factor of ten to facilitate access to mobile multimedia: faster transmission of data (receiving and sending), improved network response time to different requests… The possibilities have increased tenfold: Users will be able to share their images and videos or store and retrieve their data in the cloud, with a noticeable improvement in speed.
Deployment of 3G and 4G mobile networks by VINCI Energies
The deployment of more efficient telecommunications networks requires changes: It doesn’t consist only of manufacturing 4G-compatible mobile devices but also requires the implementation of telecommunication infrastructures capable of handling great increases in the volume of data exchanged. Through its Axians brand, VINCI Energies participates in deployment and maintenance of telecommunication infrastructures for fixed-line and mobile networks and is contributing to the rise of technologies such as mobile multimedia.
According to the director of the Axians brand, Olivier Genelot, “the new generation of mobile telephony constitutes a genuine technical revolution. The goal is to upgrade existing sites to make them compatible with the new technology.” To achieve this, it’s necessary to change equipment and modify the infrastructures (relay antennas) or expand bandwidth to transmit the DATA downloaded by users (replacement of coaxial cables by optical fiber). By 2018, two thirds of the world population should be covered by 4G.
