Fibre broadband in Switzerland: what internet coverage really means when renting or buying
Whether fibre, coax or old copper — the difference can determine whether your video call stays stable. BAKOM data shows ~85% of Swiss buildings have ≥1 Gbit/s access, but coverage varies significantly between municipalities.

~65% true FTTH (fibre to the building)
Broadband has become as self-evident as running water for many households — until you move into a new flat and find that "the internet works" means 20 Mbit/s download and 2 Mbit/s upload over DSL, shared across multiple neighbours. For a household with a home office, streaming and smart-home devices, that is a real setback. Internet quality at an address is an underrated search criterion — especially in agglomerations where fibre and coax sit side by side and coverage can vary from one address to the next.
The three technologies compared
Internet connection technologies in Switzerland
| Technology | Typical provider | Download | Upload | Future-proof? |
|---|---|---|---|---|
| FTTH (fibre) | Swisscom, EVU, Init7 | 1–25 Gbit/s | 1–25 Gbit/s | Yes — physically unlimited scalability |
| Coaxial cable (HFC) | Sunrise (ex-UPC), Salt | 100 Mbit–2 Gbit/s | 10–200 Mbit/s | Partly — upstream limited, shared network |
| VDSL/DSL (copper) | Swisscom (older deployments) | 20–300 Mbit/s | 5–50 Mbit/s | No — being phased out gradually |
| 4G/5G Fixed Wireless | Salt, Sunrise, Swisscom | 50–300 Mbit/s | 20–100 Mbit/s | Partly — coverage gaps, capacity constraints |
What BAKOM data means for your property search
The BAKOM Broadband Atlas shows per address which technologies and bandwidths are available. Homematch analyses this data at municipality level and shows you the fibre share and the ≥1 Gbit/s coverage rate. A high value means: fast internet is available for most buildings in this municipality. It does not mean your specific address is already connected — particularly with newly rolled-out fibre networks, an active connection may still take a few months.

Fibre and home office: why upload speed is the deciding factor
For consumers (streaming, browsing), download speed is the primary metric. For home office work, video calls, cloud backups and self-hosted services, upload is at least equally important. A DSL connection with 100 Mbit/s download and 10 Mbit/s upload collapses during a single simultaneous 4K video call. Fibre delivers symmetrical speeds: 1 Gbit/s symmetrical means 1 Gbit/s up and down — even with multiple people in the household active simultaneously.
What to do if coverage is poor?
- BAKOM check before signing: enter the exact address on checkbreitband.ch (BAKOM) — not the municipality, but the street and house number.
- Ask the landlord/seller: is the fibre connection activated? Which provider do current tenants use?
- Evaluate alternatives: if no FTTH, check whether coaxial cable from Sunrise/UPC is available — that also delivers ≥1 Gbit/s download.
- 5G Fixed Wireless as a bridge: if no fixed-line connection is available short-term, a 5G router from Sunrise, Salt or Swisscom can be a temporary solution — subject to network coverage.
- Municipal portals: many municipalities actively communicate planned fibre roll-outs on their website or via the building department.
Frequently asked
- How do I know if an apartment really has fibre?
- Ask for the active provider and check the BAKOM broadband map (checkbreitband.ch) for the exact address. A white or yellow fibre dot means available. Important: the in-building wiring must also be upgraded — in older buildings, internal cabling can be the bottleneck.
- Is coaxial cable (Sunrise/UPC) worse than fibre?
- For most households, no. Coaxial cable also delivers ≥1 Gbit/s download today. The differences are in upload (fibre symmetrical, coax asymmetrical) and network architecture: coax is a shared network (bandwidth shared with neighbours), fibre is a dedicated line. For intensive home office and cloud work, fibre is the better choice.
- What does "Open Access" mean for fibre networks?
- "Open Access" means the fibre network is open to multiple providers. In many Swiss cities the municipal utility built the infrastructure, but you can choose between Swisscom, Init7, Quickline and others. This is good for price comparison and provider diversity. In proprietary networks (e.g. Sunrise coax), there is only one provider.
- Does fibre affect property value?
- Yes, measurably. Studies from Switzerland and Germany show FTTH connections can increase property values by 1–5% — especially for single-family homes and in regions with otherwise weak coverage. For investment properties and commercial premises the impact can be even greater, as quality tenants treat broadband as a baseline requirement.
