5G - Vitesse Internet

Internet speed

Various tests we’ve carried out show that the speed is faster than 1Gbit/s. That's up to 10 times faster than 4G.

5G - Temps de réaction

Response time

The latency of the 5G network (delay between an action and response) will be less than 10 milliseconds.

5G - Performance


The massive connectivity. Anything can be connected and interconnected: smartphones, cars, everyday objects, security systems, medical devices, etc.

5G - Expérience 5G

5G experience

5G will give way to new digital and electronic experiences in various fields.

As you would expect, POST is preparing for 5G

The reality

5G, yes! But what is it exactly?

POST Luxembourg - 5G - Projet 5G - La 5G, oui! Mais concrètement?

Expected in 2020, 5G (fifth generation of standards for mobile telephony) is already the whole rage. But what should we really expect?

5G can be summed up, essentially, in two words:

- Speed: an Internet speed faster than 1Gbit/s. Our connections will be up to 10 times faster.

- Latency: the response time for an action will be less than 10 milliseconds.

Together these two technological advantages will bring our society into the era of hyperconnectivity. 5G will be much more than an evolution of mobile Internet for smartphones. It will be the connectivity of the future, which will improve our everyday lives thanks to the mass connectivity of objects. Over time, cars will be autonomous and will reduce road accidents (V2V); medical follow-ups can be done remotely and your doctor will be alerted if necessary following automatic diagnoses (IoMT); manufacturing productivity will be much more precise and efficient; the transmission of information will be almost instantaneous; and it will be possible to connect all everyday household objects at a lower cost. Basically, the Internet of Everything will become part of our lives and will become indispensable, just as we have already seen with the car, TV and smartphone.

5G or the Digital Luxembourg programme

POST Luxembourg - 5G - Projet 5G - Programme Digital Luxembourg

The 5G technology deployment strategy is part of Luxembourg's digitisation programme. After focusing its efforts on the 4G fixed and mobile Internet network, Luxembourg's current aim is to be a leading digital player with 5G. The reasons are two-fold. On the one hand, the country must respond to the targets adopted by the EU Telecom Ministers. On the other hand, we respond to a growing need for speed due to new uses: 4K is becoming more widespread, streaming is becoming a norm and the number of eGamers is rising. All of these habits call for a higher network capacity and low latency. But 5G is so much more! For Luxembourg, this new stage of digitisation represents a major socio-economic step forward for both individuals and businesses. Citizen's quality of life will be improved with developments in many areas: transport, industry, security, health, the Internet of Things, etc. And the deployment of 5G will also increase the attractiveness of Luxembourg by affirming that it is a ground for innovation for setting up new businesses. To sum up, in Luxembourg, 5G will be the electronic communication infrastructure of the future.

Automated driving

Self-driving cars: when technological innovation improves our quality of life and safety

Machines that talk to each other – no this isn't the storyline of Steven Spielberg's next science fiction movie, but the reality of our future. In fact, Luxembourg's Minister of Economy and Minister of the Environment, Climate and Sustainable Development together with their French and German counterparts, have approved the testing of self-driving cars, using 5G under real conditions. This experiment will make it possible for tests to be carried out on real roads, on the motorway corridor linking the cities of Metz (France), Merzig (Germany) and South of Luxembourg. This explains the name of the project – "5GCroCo" (5G Cross-Border Control). Although self-driving cars have been in the pipeline for a while, the deployment of 5G technology will make them even safer. Three areas relating to how these vehicles drive at the cross-border test site will be studied:

  • Remote driving
  • Continuously receiving and transmitting data
  • The improvement in traffic and driving conditions for motorists

Thanks to 5G technology, which is present in the vehicle and in external sensors, it will be possible to share data, not only with other vehicles but also with the surrounding infrastructure. The car will be able to react autonomously and warn motorists of dangers ahead. This will have an impact on collisions as well as on the flow of traffic, traffic jams and pollution caused by road transport. To sum up, together these three specific cases should reduce the number of road accidents by improving the motorists’ safety and comfort.

In addition, as the "5GCroCo" project is a cross-border experiment, it will be possible to test the 5G mobile network when crossing the borders. Having a permanent connection, even when crossing the border, is a real opportunity to improve safety. As such, POST wanted to be involved in the project and offer its expertise. In this way, the Luxembourgish company, leader in the telecommunications field, is positioning itself in the deployment of 5G in Europe, outside its borders.

POST Luxembourg - 5G - Projet 5G - Conduite Automatisée

As a telecommunications service provider, POST also has a decisive role to play, as self-driving cars will become a reality with the help of 5G technology. It is in fact 5G that will enable vehicles to communicate with each other and share data, continuously and in real time. Interconnectivity with other cars, but also with certain street furniture items, will make it possible to receive a large flow of constantly changing data from a number of sources outside the vehicle. To create the "omniscient" car, two components intrinsic to 5G NR (New Radio) are necessary: the amount of information transmitted via ultra-broadband (enhanced Mobile BroadBand: eMBB) and a very reliable low latency* (Ultra Reliable Low Latency Communications: URLLC). Having a very low latency, of around a millisecond, is essential for an immediate response to the dangers of the road: the reaction time of a driver travelling at 130km/hour, without fatigue, in a non-self-driving car is approximately one second, which equates to 120 metres travelled on dry road before the vehicle stops. However, when there is a risk, a self-driving car will warn other cars in one millisecond and will activate the emergency brake assistance to stop the vehicle in less than 85 metres.

Technological innovation improves our daily lives. It can even save lives.

* Latency measures the speed at which signals are transmitted through a telecommunications network.

When 5G saves lives: drones, first aid

POST Luxembourg - 5G - Projet 5G - Drones

Drones are typically used for taking aerial photographs, mainly as part of mapping processes. However, more recently there has been a lot of talk about other use cases in a fast-growing area: delivering shipments using drones. The combination of these two use cases can save lives.

Currently it is the emergency services that are called out following an accident. But they may have to overcome obstacles, depending on the incident’s location, such as uneven terrains, traffic jams, impassable roads, roadblocks, etc. All these are constraints that drones can easily overcome. Once at the scene, the drone can provide important information via a livestream video, an audio device and a thermal camera. Thanks to 5G technology, information can be sent almost instantly and the accuracy of the images –which are better than with the naked eye– will make it possible to pinpoint the location of the victim(s). Finally, thanks to its carrying capability the drone can transport small shipments, such as blood pouches, medicines and vaccines.

Therefore, 5G will help delivering vital supplies in emergency situations.

5G, our future reality

POST Luxembourg - 5G - Projet 5G - Virtual Reality

In recent years, virtual reality and augmented reality have been frequently used for connected experiences. But the arrival of 5G will give these uses a new dimension.

Virtual reality makes it possible to become completely immersed in a chosen world. 5G will bring this world as close as possible, making it almost impossible to distinguish between virtual and true reality. Users will be able to enjoy a safari from their couch and count lion's whiskers while admiring the pink shades of the sunset. It will be possible to follow the exact route of a bobsleigh at full speed at the Olympic Games or to attend a concert by a quartet made up of artists that are in different locations. It is also a step forward for the environment: 5G is the gateway to the world without having to rely on airplanes.

In addition, 5G will take the use of augmented reality to the next level. It can be used in many areas: during a football match to see the name and number of the players simply by pointing your smartphone at the TV, to rearrange a room using your tablet screen to show a sofa or a table or to try on a pair of shoes available online. But augmented reality may also appear in other less recreational areas, such as education, industry and medicine.

The technology behind 5G

POST Luxembourg - 5G - Projet 5G - Santé

5G is based on signals transmitted by radio waves, like television and radio broadcasting or cellular telephony as we know it today. In the initial phase of the deployment of the 5G network in Luxembourg, the frequency bands used will be close to those of 2G, 3G or 4G.

Thereafter, new bands with a higher frequency may be used depending on performance and capacity needs.

The 5G network operates with a new type of active beamforming antennas that allow the radio signal to be directed to users depending on their needs instead of being transmitted constantly in all directions.

Each mobile operator must comply with the maximum emission thresholds to be determined by the authorities.

In Luxembourg, the regulations limiting the electromagnetic field produced by an antenna are among the strictest in Europe.

For the EMF ("Electromagnetic Field") part, the authorisation process is very rigorous in Luxembourg. Each base station must be authorized by the competent public administrations (Environment, ITM) that regulate the emission level.

In addition, all electrical equipment, including smartphones, must comply with an exposure limit value, which is measured for each device according to its SAR (Specific Absorption Rate).
