5g Technologies – Most of our cell phones now work with 4G. But the gradual deployment of the new 5G technology is already looming, with its advantages and risks. A point on the subject.
Telecommunications have experienced rapid development in recent years. The first mobile phones made it possible to make calls while being mobile, 2G made it possible to transmit text, 3G to send images and photos, 4G revolutionized access to the Internet via our phones and global operators are already starting to place themselves on the 5G market which will allow the development of connected objects. But what are the risks of deploying this new technology? A point in this article.

5G applications
What will 5G be used for? First of all, you have to understand that it will allow a very high speed connection and that 3 things will be greatly improved: even faster downloads, extremely low latency (response time) and the exploitation of higher frequency which will significantly improve the responsiveness of connected objects.
To really imagine what 5G will really be for, you have to project yourself into the future, around 2030. Billions of objects connected to everyday life (watches, clothing, household appliances, etc.), autonomous cars , constant use of virtual reality and augmented reality , access to video streaming with always better quality images, etc.
The automobile and 5G
With the rise of 5G, the autonomous car will gain in responsiveness and safety. Current tests show that it takes about 1 meter for the vehicle to initiate a braking procedure.
Thanks to 5G, which allows greater bandwidth and a reduced response time, the autonomous car will be able to analyze its environment faster and more efficiently. It will only take a few centimeters to brake in the event of an obstacle for example. His ability to react to all situations, emergency or not, will be greatly refined .
The health benefits of this technology
Many data are currently processed, stored and transmitted in hospitals. One can imagine that the processing and the transmission of the data will be facilitated .
On the other hand, the appearance of connected devices will make it possible more and more to exchange in real time on the health of a patient, to inform his doctor or emergency services automatically in the event of a problem, or simply ensure better monitoring.

5G – Advantages & Disadvantages
In the not so distant future, we can imagine that our whole environment will be connected and interconnected : a watch that will tell you what’s left in your fridge, the dishwasher that will send you a notification to notify you of a breakdown, the house which will warm up by detecting your next arrival, etc. All this already exists on an experimental basis or in a still relatively “primitive” form, but is bound to improve and popularize. 5G will make these data exchanges extremely fluid .
The same goes for the industry where it will allow even greater automation, an improvement in the interconnection between machines and / or systems, downloads of optimized information and information in real time which will allow constant and very precise adjustment.
No more connected objects, no more hacking
5G technology is said to be much safer than the 4G technology we currently use. However, even if the security vulnerabilities will be smaller, they will also be much more numerous because this technology is bound to become ubiquitous in our daily lives.
Sylvain Chevallier, partner at Bearing Point, a telecommunications specialist, reminds us: “Tamper-proof security systems do not exist”. “ The 5G network will be permissive, like all networks “.
“It can be pretty chilling to imagine that someone could take control of your vehicle remotely and make you do anything,” he adds.
And if we go in this direction, everything is imaginable and somewhat frightening. Hackers who would take control of an industrial production chain, hacking of ultra-sensitive medical data, private and industrial espionage, etc.
Ericsson, Nokia and Huawei are at the forefront of 5G technology
For the moment, 3 manufacturers are leaders in the 5G market. Swedish Ericsson, Finnish Nokia, and Chinese Huawei, which is the best performing operator currently according to specialists. In a context where data security is a priority, the Chinese giant has already been banned from developing its technology in several states who fear that Beijing will use this technological advance for industrial espionage or to launch cyber attacks.
Regarding the daily life of Mr Everyone, specialists announce a gradual arrival of 5G around 2023 or 2025 . Probably by then massive progress will also be made in terms of data security.
