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 digitalisation 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 digitalisation 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).

POST Luxembourg - 5G - Flashback
POST Luxembourg - 5G - Flashback


1. What is 5G?

5G is the fifth generation of standards developed for mobile telephony. It goes beyond the capabilities of LTE technology, in other words 4G. 5G and 4G technologies (as well as 3G and 2G) will both be available over the next years.

2. Why has 5G been rolled out?

In order to meet the growing connectivity needs of both private and business customers, the Internet speed needs to be even faster and the latency even lower, for a growing number of users and connected objects. By 2023, 4G will have reached its limits due to the saturation of the current network. Every year, data connections increase by 40% and the 4G network will eventually no longer be able to handle the growing number of connections. 5G is also part of the digitalisation evolution in Luxembourg in general, as well as the development of POST’s “Network of the future”.

3. What are the characteristics of 5G?

5G is a change of generation (the transition from 4G to 5G), which will offer very high-speed access, with very short latency times, which, in the B2C sector, will improve the customer experience and open up new opportunities for applications, for example in self-driving cars. Owing to its very high degree of reliability, 5G will also make it possible to set up remote control and command applications in many fields in the B2B sector, as well as in the health sector, for example in remote surgery and industrial automation, etc.

4. What are the major differences between 4G and 5G?

Compared to 4G, 5G will offer a connection speed that is 20 times faster and a response time that is 10 to 30 times shorter (latency).

5. What speed will 5G be able to reach?

5G has the potential to be up to 1,000 times more effective than mobile networks used in 2010 and up to 20 times faster than 4G.

6. What does latency mean and what does it mean for 5G?

Latency is the time it takes to respond to a request for action. This ultra-short latency time will be very important in the future use of 5G, such as in remote surgery for example.
The 5G network response time will be in the range of a few milliseconds, well below the 10 to 40 milliseconds with existing 4G.

7. What frequencies will 5G use?

The frequencies currently allocated for the 5G network are 700 MHz and 3.6Ghz. 5G will therefore use the same wavelength range as previous technologies, but in a more effective way, and is therefore less energy-intensive.

8.How will the use of frequencies change?

Today, the frequency spectrum used by 2G, 3G and 4G is between 800 MHz and 2600 MHz (2.6 GHz).

5G will be activated on frequencies very close to the current frequencies: 700 MHz and 3600 MHz (3.6 GHz).

Low frequencies (700-800 MHz) allow better signal penetration, unlike higher frequencies (3.6 GHz) which offer a higher capacity and speed but less coverage. That is why, for example, WiFi at 5 GHz does not propagate as well in homes as WiFi at 2.4 GHz.

9. Will there be a 26 GHz band in Luxembourg?

In Europe, the 26 GHz band is planned for additional 5G capacity needs in the future. It is up to the Ministry of State to establish the time frame for allocating this band in Luxembourg at a later stage.

In the future, frequencies in the 26 GHz band could be used for temporary 5G coverage needs.

10. What are the maximum emission thresholds for mobile networks in Luxembourg and who monitors them?

In Luxembourg, the limit for electromagnetic fields produced by a base station is among the strictest in Europe (3V/m per antenna in residential areas).

As for EMF ("Electromagnetic Field"), the authorisation process is very strict in Luxembourg. Each base station must be authorised by the authorities concerned (the Ministry of the Environment and ITM) which control the emission level.

11. Will it still be possible to use 4G? Will all POST’s customers be required to use the 5G network?

4G will remain available and operational. Using 5G will be optional.

12. Will the 3G network be phased out?

It is intended to replace the 3G network over the next years (>2022) with 4G and 5G technologies. We believe that 2G will remain available for a longer period of time, as a basic mobile technology.

13. Who is responsible for the deployment of 5G and the antennas in Luxembourg?

Each mobile operator, holding a relevant frequency licence, is responsible for rolling out its own 5G network.

14. What are the applications of 5G?

5G aims to meet a growing demand for data traffic via smartphones and communicating objects, which are growing in number and connected to the network. It can be used in a wide range of fields, such as in medicine, security devices, entertainment, the media, logistics, cars, industry, surveillance, e-gaming and e-sporting, etc.

5G should also promote cloud computing, integration, the interoperability of communicating objects and smartgrids and other smart networks, in an automated environment, helping to promote the concept of “smart city”. It may also contribute to the development of 3D image synthesis or holography, data mining, the management of big data and the Internet of Everything (an expression referring to a world in which computers and peripherals can communicate with each other).

15. Is it already possible to use 5G in Luxembourg?

On 16 October 2020, POST launched the first sites of its 5G mobile network on the territory of the City of Luxembourg and other pilot areas. POST's 5G coverage will be extended to other regions, including the Ettelbruck and Diekirch areas in early 2021, the urban areas in the south of the country during 2021 and then gradually the rest of the Grand Duchy.

16. Is a WiFi network no longer necessary with 5G?

The two technologies will remain available depending on the needs and situation of the users.

17. Is 5G more effective than fiber optics?

Fiber optics remains the most effective way to access ultra-broadband because the bandwidth is not shared with other users, unlike a mobile phone tower which is shared between several users. 5G will, however, give some customers, who are not yet connected to the fibre-optic network, the opportunity to connect to ultra-broadband using a 5G router.

18. When will POST customers be able to use 5G?

On 16 October 2020, POST launched the first sites of its 5G mobile network on the territory of the City of Luxembourg and other pilot areas. POST's 5G coverage will be extended to other regions, including the Ettelbruck and Diekirch areas in early 2021, the urban areas in the south of the country during 2021 and then gradually the rest of the Grand Duchy.

19. Who is your provider for the POST 5G network?

POST's 5G network will be deployed on the Ericsson network infrastructure, POST’s legacy and current mobile network provider.

20. Are the 5G frequencies sufficient for POST ?

The 5G frequencies, 700 MHz and 3.6 Ghz, were awarded to Luxembourg through an auction in July 2020.
POST was allocated large amounts of spectrum, 20 MHz for the 700 MHz band and 110 MHz for the 3.6 GHz band. This puts POST among the leading European operators and it is able to develop high-performance 5G services and add additional capacity to its entire mobile network.

21. Is it necessary to have a POST mobile plan to be able to use POST's 5G

Yes, it is necessary to have a POST mobile plan to be able to use POST's 5G network.

22. What are the prerequisites for using 5G?

It will be necessary to have a mobile plan and a 5G compatible mobile, and to be in an area covered by 5G.

23. Will POST offer 5G compatible smartphones?

Yes, POST already offers 5G compatible smartphones.

24. How is POST going to deploy the 5G network in Luxembourg?

POST Luxembourg is investing in the development of the “Network of the future”, which includes fixed networks, including fiber optics, as well as the current mobile network. Over the next years, 4G and 5G technologies will both be available on the mobile network. POST estimates that the overall investment in 5G will be tens of millions of euros over the next decade. In accordance with the requirements of new frequency licences, POST will install the first 5G coverage cluster in Luxembourg City before the end of 2020. It will then be extended gradually to cover, eventually, the entire country. As with 4G, POST will develop specific 5G roaming agreements so that its customers can enjoy it anywhere in Europe.

25. What is POST's position on the “Stop 5G Luxembourg” petition?

POST is aware of the fears that 5G may cause. Locals and users should therefore be well informed of the factual information available to date.

26. Is the use of 5G reliable and secure?

5G technology has been developed in "security by design" mode. Security has been considered from the systems design phase.

27. Which measures, if any, have been taken to ensure the security of the infrastructure and data disseminated?

Information security is an important aspect for all POST services: Telecoms, Post, Finance. In terms of cybersecurity, we follow the recommendations from the European Commission (EC), particularly those provided in the “5G EU Toolbox”, published at the end of January 2020. The objective of this “Toolbox” is to define a coordinated European approach based on a common package of measures, aimed at mitigating the main cybersecurity risks of 5G networks that have been identified in the EC Coordinated Risk Assessment Report.

28. Does mobile telephony pose a risk to public health, animals or the environment ?

No data currently available from among the many scientific studies that have been conducted on this subject for several decades have shown any risk. The only observation was a slight increase in body temperature. The principle of prevention, however, still applies and POST scrupulously follows the criteria on emissions established by the Luxembourg authorities, which are among the strictest in the world.

29. Does 5G create more electromagnetic fields?

5G uses the same signals transported by radio frequency waves as television broadcasting, radio broadcasting and mobile telephony as we know it today. The exposure limit values for electromagnetic fields apply regardless of the technology.

30. Is 5G more dangerous than other connectivity technologies (3G, 4G, WiFi, Li-Wi, Radio, DECT, Satellites, Babyphone, Bluetooth, etc.)?

At present, none of the many scientific studies that have been conducted on this subject for several decades have shown any risk. The only observation was a slight increase in body temperature. The principle of prevention, however, still applies and POST scrupulously follows the criteria on emissions established by the Luxembourg authorities, which are among the strictest in the world.

31. Magnetic fields are classified by WHO as “potentially carcinogenic”. Is there any need to be concerned about a risk to public health?

There are four categories: 1 (carcinogenic), 2A (probably carcinogenic), 2B (possibly carcinogenic), 3 (unclassifiable) and 4 (probably not carcinogenic). Radiofrequency electromagnetic fields (mobile phones, base stations (phone towers), wireless phones (DECT), Wi-Fi2, etc.) are classified in category 2B.

Note that the WHO classifies coffee in category 2B.

At present, none of the many scientific studies that have been conducted on this subject for several decades have shown any risk. The only observation was a slight increase in body temperature. The principle of prevention, however, still applies and POST scrupulously follows the criteria on emissions established by the Luxembourg authorities, which are among the strictest in the world.

32. When 5G is rolled out in Luxembourg, will there be an increase in the number of antennas?

Initially, POST will not increase the number of antennas required for 5G. 5G coverage can normally be provided by the existing sites.

However, increasing the number of antennas improves coverage while reducing the electromagnetic fields emitted by each antenna. So, the closer a smartphone is to an antenna, the less powerful its electromagnetic signal is. In any event, the number of antennas deployed will depend on applicable regulations in this respect.

33. Are municipalities involved in planning the roll-out of the 5G network?

In general, to set up a mobile network, it is necessary to have a construction permit, issued by the municipality concerned in accordance with its construction regulations.

34. Do I need any specific equipment to be able to use the 5G network?

To use 5G, it is necessary to use a smartphone or any other connected device that is compatible with 5G technology, and to have a POST 5G plan.

35. Is my "device" (smartphone, tablet, connected object, etc.) compatible with 5G?

The technical specifications provided by the manufacturer of the device will provide the user with information about its compatibility with 5G.
