GSM Network in wireless MOBILE communication
Since the arrival of the first cordless telephones in the 80s, mobile telephony has evolved exponentially. Networks are constantly evolving and we are now at 5G, the 5th generation. They no longer only transport voice, but an ever-increasing quantity of data generated at every moment by our digital and mobile uses.
However, this mass of data must be accessible everywhere, all the time, and instantly!
Connection capacity, speed, responsiveness… since the 1st generation of mobile technology, networks have evolved to meet needs! Let’s us take a look back at 5 generations of mobile networks to understand the interest and challenges of 5G!
1980s: 1G and the first mobiles
Appearing in the early 80’s, the first “cell phones” appeared with 1G or 1st generation cellular technology. saw the appearance of the first “mobiles”. Mobiles in quotation marks, since at that time telephones were more portable rather than portable. Heavy and bulky their use was essentially professional.
This first generation was analog and allowed only allowed voice exchanges. Furthermore, roaming from one country to another was impossible because the networks were not standardized and each country had its own standards.
1990s: with 2G, analog gives way to digital technology
A small revolution in the mobile phone world, the G lobal System for Mobile Communications ( GSM ) is adopted. This digital international standard allows you to add communications in text or image form! SMS (Short Message Service) and MMS (Multimedia Messaging Service) were born! Theoretical maximum speeds can reach 384 kilobits per second.
Standardization makes it possible to use the phone abroad!
Mobile internet time
2000s: 3G brings mobile broadband
While 2G was primarily used for telephoning, 3G marks the advent of mobile Internet access. Laptops are becoming smartphones, and allow you to watch videos, browse the web, check your emails… Speeds increase up to a maximum of 42 megabits per second, but connections are sometimes capricious.
2010s: 4G REALLY brings mobile broadband
With my multiplication of uses and the increase in the size of content increases, so does the volumes of data exchanged are constantly increasing.
With speeds that can theoretically reach 1 gigabit per second, 4G allows the generalization of nomadic uses and the exchange of large quantities of data. Smartphones can “do it all “everything” and allow you to view high-resolution images or videos. They are gradually replacing computers in many uses… and are also used for telephone calls!
Instantaneity and everything connected 2020s: 5G and everything connected
2020s: 5G and everything connected
2020s: 5G and everything connected 5G was developed to meet the growing needs for connection and instantaneousness introduced by our digital society brings.
By allowing 1,000,000 connections per km2, 5G aims to avoid network congestion in dense areas while offering a speed 10 times higher than that of 4G (up to 10 gigabits).
This technology is able to adapt to needs by prioritizing on demand, speed, responsiveness or connection capacity depending on the need. It is therefore perfectly suited to the “all connected” that is coming our way: connected vehicles, e-health, industry 4.0, smart city.
High speed and capacities for all uses that require a very large size and download speed: applications and video games, 4K videos, augmented reality, data storage, etc.
Internet of things and energy efficiency for uses involving communication between a large number of connected objects: smart city, connected buildings, etc.
Low latency and high flexibility for real-time applications that require a lot of reactivity: industrial automation, autonomous vehicles, critical applications…
Finally, 5G is intended to be “greener” than 4G, since this technology makes it possible to consume at least half the energy for the same quantity of information transported!
And after that? In a few years, we will certainly be talking about 6G… an ever more powerful and probably even more efficient technology for the environment! We will talk about it soon!
Stay Tuned …
