5GCroCo (Fifth generation cross-border control)

POST Luxembourg - 5G - Projet 5G - 5G Croco

Launched in 2018, the 5GCroCo (5G Cross-Border Control) project is a joint undertaking by the Ministry of the Economy and the Ministry of Sustainable Development and Infrastructure, working in collaboration with their French and German counterparts. The project establishes a testing site for connected and self-driving vehicles. This will be set up along the borders of Luxembourg, Germany and France to provide cooperative, connected and automated mobility (CCAM) services.

Involving several major players in Europe’s automotive and mobile communications sectors, the project will cover three specific case studies: remote driving, real-time generation and diffusion of high-definition maps, and early prevention of collisions.

The 5GCroCo project demonstrates the three countries’ shared commitment to promoting the development and testing of the various technologies in a real-world, cross-border context.

As part of this European project, and to test the use of 5G technology in this context, POST Luxembourg has been selected by the European Commission to provide 5G coverage for the Luxembourg section of the motorway linking Metz, Merzig and the Grand Duchy. The aim is to conduct testing of 5G technology at scale in order to meet the needs of connected and self-driving vehicles.

5GLila (Living Lab for Digital Transition in Healthcare towards 5G)

POST Luxembourg - 5G - Projet 5G - 5G Lilia

POST is supporting the Lila5G project initiated by CHEM in conjunction with the Communications and Media Service of the Luxembourg Ministry of State. The project, which brings together patients, service providers, facilities and support services, aims to improve the overall treatment experience in the healthcare sector.

There are a number of immense challenges facing the healthcare sector, including the ageing population, the rising prevalence of chronic illness, the issue of recruiting medical and nursing staff, and the budget. Digitisation is the key to solving these problems and 5G can help create more efficient and responsive clinical processes.

Achieving the aim of this project will therefore entail creating a smart hospital campus that will allow for remote surgery, monitoring of doctors’ locations, the operation of smart buildings, smart waste and water management, mechanisation of patient transport in real time throughout the hospital, and surveillance of critical infrastructure and equipment. The ambitions behind the project include creating an integrated MRI and patient sensor system as well as fast, reliable, secure and unified mobile communications for accessing the hospital’s critical data.

As an active contributor to quality of life, POST is involved in two aspects of this project: provision of 5G coverage at CHEM Dudelange and Network Slicing Tests once these become available.

DigiWald (Waldbillig gëtt Digital)

POST Luxembourg - 5G - Projet 5G - Digiwald

The Luxembourg commune of Waldbillig is demonstrating its determination to improve the digitisation of the area and develop a form of smart city through its DigiWald project. The aim of this project is to modernise the commune’s infrastructure and improve communications for residents. In collaboration with POST, Waldbillig is testing a new product (5G router) in households where coverage is insufficient at present. The benefit of this new product is that it offers a high-speed internet connection via POST’s 5G network.

To see the project through to completion, the commune of Waldbillig and POST are providing households taking part in the test with the equipment they need, free of charge, for 24 months. The test equipment includes 5G FWA modems and Sigfox smart meters. As well as free internet services, participating residents can also enjoy PostTV services (OTT). Lastly, interactive 5G smart screens are being used to improve communications for residents.

MICRO5G (Mobile Edge Computing for 5G Drone Systems)

POST Luxembourg - 5G - Micro 5G

The list of potential applications for drones keeps on growing in sectors such as healthcare, logistics, transport and public safety.

In light of this, the aim of the MICRO5G project is to acquire new skills and knowledge in relation to ultra-reliable low latency communications (URLLC) and mobile edge computing (MEC) as part of the process of rolling out and supporting drone services in 5G applications and beyond.

Involving the emergency services in particular, this project is enabling drones to be flown remotely in a disaster area using a backhaul satellite link.

For this project, a mobile base station will be built with a satellite link to the heart of POST’s 4G network and 5G network coverage will be re-established within the test zone via satellite backhauling.

5G will therefore pave the way for innovative services such as secure flying beyond the visual line of sight (BVLOS) and dynamic navigation/geofencing. In this way, the project will promote interactive, rather than independent, integration of the various 5G technologies.

POST, which invests heavily in innovation, is working with SNT and handling 5G coverage in the SNT Kirchberg building and on the mobile site.

Partners: University of Luxembourg/SNT, SES, POST

Lux5Gcloud (Luxembourg 5G Smart Country Data Cloud)

POST Luxembourg - 5G - Lux 5G cloud

In light of climate change, agricultural areas are facing new pressures, such as critical weather events (droughts, floods), for which farmers need accurate and real-time monitoring to manage their crops. However, these areas often lack the connectivity that would allow the development of smart applications.

In this context, the Lux5GCloud project will conduct and demonstrate the advantages of 5G and its advanced technologies to develop an innovative and secure Cloud Hierarchy Database Platform (CHDP) allowing all end-users – from farmers to scientists and policy makers – to monitor, automate, and analyse their operations.

Lux5GCloud will enable an accurate monitoring of soil moisture shortages, which is a pre-condition for managing drought adaptation and ecosystems resilience, such as foreseen by the EU Nature restoration plan of the EU Biodiversity Strategy for 2030. Hence, this innovative project will also pave the way for follow-up projects targeting the development of a CHDP prototype in Luxembourg, and its future commercialisation on the market, in close collaboration with relevant stakeholders.

POST is supporting the Lux5GCloud project with a view to facilitating the transfer of information, data and content and ensuring 5G coverage at the BCL, Fischmarkt, Belval Agora and Ibis sites. POST is also committed to the implementation of Blockchain technology.

5GNord (5G – Smart Water Eislek)

POST Luxembourg - 5G - Projet 5G - 5G nord

5GNord is a project focused on water distribution where the aim is to improve remote monitoring of the water distribution network. More specifically, the project seeks to develop a 5G IoT (Internet of Things) system comprising sensors (water meterage, pressure, temperature, etc.), 5G communications and online visualisation for data analysis purposes. The plan is to use the data collected to reduce leakage of drinking water and better analyse water supply. Estimating the size of water reservoirs and reducing stagnant water will improve the supply and quality of drinking water.

As part of this project, several households have already been equipped with smart meters and a customer portal has been created to make the data visible to end customers. A centralisation pathway for the data collected is also under development. In support of the 5GNord project and its aim of making the world more accessible through digitisation, POST is taking care of 5G coverage in Useldange, a test zone.

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.
