If 4G is still struggling to be deployed throughout some countries, operators around the world are currently preparing the arrival of the new generation: 5G. Between increased data speed, digital revolution, ultra-connected objects, discover the changes that await you by switching from 4G to 5G.

Reminder of what 4G is

Appeared at the end of 2011, 4G, the 4th generation of mobile network, was very quickly installed overseas to replace the previous generations 3G, the 2G, and 1G network. If it succeeds the 3G network, it is above all for its significant increase in its connection speed, from 144 Kbit / s for 3G to 75 or 150 Mbit / s for 4G.

This revolution has had many advantages making life easier for users: speed of downloading for large files, acceleration of the loading time of streaming videos, but also better quality of network games.

4G +, a first step towards 5G

While 4G continues to conquer some perimeter, operators have worked simultaneously on a more optimized version: LTE-Advanced, better known as 4G +.

Launched in 2014, 4G + stands out from 4G. 4G + offers a speed between 200 and 300 Mbit / s. It is therefore twice as fast as 4G. How does 4G + work? 4G + can be connected simultaneously to several 4G frequency bands.

What are the advantages of 5G?

While 4G and 4G + networks gain territory and offer already significant speed for consumers, the needs of individuals, businesses and governments continue to grow with technological developments. All users want more speed, lower latency, and be ultra-connected.

While 3G and 4G networks were designed to meet a need for speed on the mobile internet, 5G aims much higher. A fully connected future, that is its goal. To achieve this, the members of the 3GPP (3rd Generation Partnership Project) have already validated the characteristics of 5G to achieve a domotized environment where each object will be connected.

Your house or even your car will also be connected to you for more safety and optimal comfort of life. Even if it is not for tomorrow, autonomous cars will be part of our daily life thanks to 5G. In the field of self-driving cars, the speed of the 5G network will make it possible to limit braking distances because the information will be processed and transmitted much more quickly.

5G will use millimeter waves to reduce latency and further increase throughput. Finally, it will be a responsible network since it will reduce the energy consumption of our mobile devices.

In summary, compared to 4G, the 5G network will offer:

  • A connection speed 100 times faster than 4G, reaching up to 100 Gbit / s.
    very low latency: latency corresponds to the time that elapses between the request and the response which marks the start of a download. With 5G, data transfer will become almost simultaneous.
  • high density, allowing the use of a greater number of users and connected objects in a small area without overloading the network. Thanks to 5G, many users will be able to be connected simultaneously without the connection speed decreasing.

What about 6G?

Logically to succeed 5G, the 5th generation of mobile telephony, 6G should make its appearance in a few years. If we stick to the calculations, the 6G network should see the light of day around 2030, even if no official information has yet been transmitted by specialized international agencies.
