Key figures for fibre coverage in Luxembourg 2026
The ILR’s 2024 annual statistical report, published in June 2025, provides a detailed picture of Luxembourg’s very high-capacity network rollout. The figures confirm Luxembourg’s leading position in Europe.
A landmark figure: in 2024, FTTH fibre coverage (83.8%) exceeded cable coverage (83.3%) for the first time. This confirms that fibre is now the dominant network technology in Luxembourg. According to the FTTH Council Europe’s 2025 Market Panorama report, Luxembourg reached 84.8% FTTH/B coverage, with an adoption rate of 62.9% and a penetration rate of 53.3% — well above the EU average of 39%. Around 267,000 homes are now connected to FTTH, representing annual growth of 15.6%.

How deployment has progressed since 2020
FTTH coverage has grown from approximately 72% in 2020 to 83.8% in 2024 — a gain of nearly 12 percentage points in four years.
| Year | FTTH coverage | VHCN coverage (≥1 Gbps, all technologies) | Subscriptions ≥1 Gbps (market share) |
|---|---|---|---|
| 2020 | ~72% | ~88% | ~2.6% |
| 2021 | ~74% | ~90% | ~4% |
| 2022 | ~77% | ~92% | ~7% |
| 2023 | 80.3% | 94.7% | ~12.2% |
| 2024 | 83.8% | 95.5% | 14.4% |
Sources: ILR statistical reports 2020–2024. 2020–2022 figures are approximations from available reports; 2023–2024 figures are from official ILR reports.
Subscriptions to gigabit-speed connections grew 51.7% in 2024 alone (from 31,200 to 47,300 lines) — confirming that consumer demand is closely following network expansion. Infrastructure investment reached €140.2 million in 2024, representing 22.4% of sector revenues, well above the European average of 12–15%.

Fibre vs cable: two complementary networks
Understanding Luxembourg’s coverage figures requires distinguishing two technologies.
FTTH fibre
- Symmetric speeds up to 8.5 Gbps
- Ultra-low latency (1–5 ms)
- Stable performance at peak times
- Dedicated individual connection per home
- Scalable infrastructure for future speeds
DOCSIS 3.1 cable
- Up to 1 Gbps download, asymmetric upload
- Moderate latency (10–30 ms)
- Performance varies with network load
- Shared bandwidth per geographic segment
- Stable network, limited further expansion
Point-to-point (73% of households, end 2024)
Each home has a dedicated fibre from the operator node. Deployed in urban and suburban areas. Enables full physical unbundling by alternative providers — you are not tied to POST even though they own the cable.
Point-to-multipoint (rural areas)
A fibre is shared between several homes from the main node. Reduces deployment costs in low-density areas but makes classical unbundling more complex. POST Technologies favours this topology for remaining rural zones.
Which areas are covered by fibre?
Luxembourg City and its suburbs (Leudelange, Walferdange, Strassen, Bertrange, Hesperange, Niederanven…), the southern cantons (Esch-sur-Alzette, Differdange, Pétange, Sanem) and the Capellen canton enjoy FTTH coverage often above 90%. Some communes like Leudelange and Hobscheid have 100% household coverage according to operator-declared data. The central and eastern cantons (Mersch, Grevenmacher, Remich, Echternach) are generally well-served, with coverage typically above 75–80%.
Topographic factor: the northern Oesling region (Clervaux, Vianden, Wiltz, Redange, Diekirch cantons) is the main challenge. Its hilly, forested landscape and low population density make infrastructure deployment 2–3× more expensive per km² than urban areas — explaining the later deployment schedule in this region.
What’s the coverage at your specific address?
Area coverage rates don’t tell the whole story — your individual building may or may not be internally cabled. Check your exact eligibility using our comparison tool.
Areas not yet covered by fibre
At end 2024, 16.2% of households still need future FTTH deployment — roughly 40,000–45,000 homes. Two distinct situations exist.
Addresses where fibre hasn’t reached the street
Mainly isolated rural areas in the Oesling region and a few low-density communes. These are being progressively covered according to POST Technologies’ deployment roadmap and the national ultra-broadband strategy.
Buildings not yet internally cabled
The most common situation in older apartment buildings, including in Luxembourg City. Fibre runs past the building, but internal cabling from the basement to each flat hasn’t been installed. The 2017 broadband law simplifies the necessary co-ownership vote (simple majority suffices). The LetzConnect initiative supports building managers in this process.
The internal cabling barrier: according to the ILR, 27% of households are not yet covered by a P2P FTTH infrastructure enabling full unbundling (2024 data). For many of these, fibre runs past the building but internal cabling hasn’t been done yet. Contact your building’s syndic to initiate the process — it’s simpler than it looks with the 2017 legislation in place.
How to check coverage at your exact address
The Switchr comparator (fastest)
Use our online comparison tool. After entering your address, you get a list of operators and offers available at your specific address — FTTH fibre, DOCSIS cable or other technologies.
The ILR interactive map (myilr.lu)
The Institut Luxembourgeois de Régulation provides an interactive coverage map at myilr.lu, searchable by address, commune or 1 km grid. You can filter by technology (fibre, cable) and infrastructure operator.
Directly with operators
Each operator has an eligibility checker on their website: POST Luxembourg (posttechnologies.lu), Orange (orange.lu), Tango, Luxembourg Online, Eltrona — each has online tools or you can contact their customer service directly.
Checkmynet.lu — measure actual speeds
To measure actual speeds on your current connection, use the free ILR tool checkmynet.lu. If results are significantly below your contractual speeds, contact your provider, then the ILR mediation service if unresolved.
Important distinction: the ILR map shows physical infrastructure presence, not necessarily all commercial service providers at that address. Always verify eligibility directly with an operator to confirm your specific apartment can be connected.

Unbundling: multiple providers on the same network
Coverage and provider choice are separate things in Luxembourg. Even where POST Technologies has deployed the fibre, you can choose an alternative provider via unbundling.
Physical unbundling (local loop access)
The alternative operator installs its own active equipment at POST’s co-location points. Available primarily on the P2P FTTH network (73% of households end 2024). This enables fully independent service offers.
Bitstream access (wholesale access)
The alternative operator leases capacity on POST’s network without deploying its own active equipment. At end 2024: 26,800 bitstream lines and 9,200 VULA (Virtual Unbundled Local Access) lines. POST supplied 86,100 wholesale access lines to alternative operators in total, including Tango (Proximus), Orange and Luxembourg Online.
What this means for you: even if POST Technologies deployed the fibre in your street, you’re not obliged to subscribe with POST. Orange, Tango, Luxembourg Online and others can offer their plans on the same network. Always compare all available offers at your address on our internet providers guide.
National targets and the path to 100% coverage
The national ultra-broadband strategy 2021–2025 targets universal access to a VHCN network (≥1 Gbps download / ≥200 Mbps upload). With 95.5% achieved at end 2024, this is largely met.
Key deadline — copper phase-out by 2030: all DSL connections on copper pairs will be replaced by very high-speed alternatives by end 2030. At end 2024, addresses with only copper infrastructure represented approximately 5% of the total — rapidly declining. Track your line’s migration status at myilr.lu/arret-du-cuivre. If you’re still on ADSL or VDSL, POST is legally required to offer you an equivalent or better alternative before the cutoff.
For the remaining 16.2% in FTTH terms, POST Technologies is deploying P2MP architecture in rural areas to reduce costs. Where private deployment is not commercially viable, the government can provide targeted public support under EU state aid rules. A draft law to facilitate deployment in market failure zones is currently under consideration.

My address isn’t covered yet: what are my options?
Cable internet (DOCSIS 3.1)
If you’re in Eltrona’s coverage area (83.3% of households), DOCSIS 3.1 cable gives you very high speeds — up to 1 Gbps download. An excellent fibre alternative for everyday domestic use. See our guide on cable internet in Luxembourg.
Fixed 5G internet
5G reaches 75.8% national coverage at end 2024 (ILR). POST Luxembourg offers a fixed access solution via 5G router (POP Internet W) — ideal for un-fibred areas with good 5G coverage. Speeds can reach 1 Gbps and above. See our guide on fixed 5G internet in Luxembourg.
Satellite internet (Starlink)
For the most remote locations without quality fibre or cable coverage. Starlink offers speeds of 100–200 Mbps with 20–40 ms latency — far superior to traditional satellite solutions. See our guide on satellite internet in Luxembourg.
ADSL/VDSL (awaiting migration)
If you’re still on a copper connection, you will be migrated to a very high-speed technology before 2030. Contact POST to find out the migration schedule planned for your address.
Luxembourg’s position in the European fibre ranking
With 84.8% FTTH/B coverage, Luxembourg significantly outperforms the EU39 average of 74.6% and the EU27+UK average of 69%. Its 53.3% penetration rate exceeds the European average of 39%. FTTH subscriber numbers jumped 36.8% in 2024 (123,000 to 168,000). Luxembourg is well placed to meet the EU Digital Decade 2030 targets of gigabit connectivity for all households before the deadline.

Frequently asked questions — fibre coverage Luxembourg
What’s the difference between « coverage » and « eligibility » for fibre?
« Coverage » means fibre infrastructure has been deployed in your geographic area. « Eligibility » is more precise: it tells you whether your specific home can actually be connected right now. A building can be in a covered area but not be internally cabled, making the address ineligible for immediate connection. Always check eligibility for your exact address rather than relying on general coverage rates.
Why isn’t my building fibred even though fibre runs past my street?
This is one of the most frequent situations in Luxembourg, especially in older apartment buildings. Fibre may be deployed in the street (passive infrastructure), but the internal cabling within the building — from the basement to each flat — hasn’t yet been installed. This requires the agreement of the building’s co-ownership management (syndic) or the landlord. The 2017 broadband law facilitates this process (simple majority vote is sufficient). Contact your syndic directly to initiate the process.
When will Luxembourg achieve 100% fibre coverage?
There is no officially confirmed date for 100% FTTH coverage. The 2021–2025 national strategy targeted universal VHCN coverage — broadly achieved with 95.5% by end 2024. For FTTH specifically, POST Technologies is actively deploying in remaining areas using P2MP architecture in rural zones. The copper phase-out deadline of 2030 is the most binding timeline — all homes must be connected to a very high-speed alternative by then. Track progress at myilr.lu.
Does fibre coverage differ by operator?
The physical infrastructure (cables in streets and buildings) is primarily deployed by POST Luxembourg. But multiple operators can offer services on this network via unbundling: Orange, Tango (Proximus), Luxembourg Online and others. Eltrona, by contrast, operates its own separate cable network. The ILR map shows infrastructure operators at a given address, but not necessarily all commercial service providers. See our internet providers guide for a full comparison.
Do advertised speeds match actual performance?
Not always. Advertised speeds are theoretical maximums. Actual performance depends on the technology (fibre vs cable), your router, Wi-Fi configuration and network load. Measure your actual speeds using the free checkmynet.lu tool. If results are significantly below your contractual speeds, contact your operator, then the ILR mediation service. See also our guide on internet speed tests in Luxembourg.
