We continuously extend the fibre-optic network and improve Internet speeds for our customers. You can check online if an expansion is planed near you in the next 12 months or so:
You can check whether the fibre-optic network is going to be expanded near you at www.swisscom.ch/checker. This will also show the Internet speed that will then be available at your location. If you want to receive updates on the expansion, you can register there and we will notify you as soon as there is news about the network expansion in your area. If no additional information is displayed on your account then no expansion is currently planned for your location.
My Swisscom (Customer Center) displays details of whether your location is going to be included in the expansion of new and faster Internet technology. My Swisscom will list one of the following options for your area:
New FTTH technology permits speeds of up to 10 Gbit/s. To date, Swisscom has connected 5.26 million homes and offices throughout Switzerland. Just under 30% of these have been upgraded to FTTH.
Requirements for 10 Gbit/s:
Would you like to switch to speeds of 10 Gbit/s? Check in the availability checker whether your location is developed for this speed and can provide enough power for your connection.
Unfortunately we cannot provide an exact expansion date at the start of the work. If technical difficulties occur during construction or there are objections from the community or property owners, it can lead to delays in network expansion. As expansion progresses we will be able to estimate the completion date more accurately.
Swisscom recommends the following applications for speed measurements:
Note that with a browser-based speed test, the values measured depend heavily on the browser. For this, Swisscom recommends testing via the Home app or the web portal of the Internet-Box. If you would still like to use one of these speed tests, do the following to maximise accuracy:
The speed that can be achieved when using a service on your smartphone, PC, tablet etc. depends on two factors:
Also note that some of the data (approximately 15%) is there to ensure transmission quality. This reserved bandwidth cannot be used to transmit content (such as photos, movies or music). 8 Gbit/s is the maximum usable speed for all devices in the home network together (including WLAN).
The maximum achievable speed for one device over the fastest Ethernet connection (Internet-Box 4) is 8 Gbit/s. When uploading and downloading simultaneously, the speed may be limited to 6 Gbit/s.
Even with the fastest Internet subscription, the speed will always be limited by the capacity of the home network and the device on which the measurement is made.
For example, an older computer that is connected correctly to the Internet-Box by an Ethernet cable and is included in the 10 Gbit/s subscription will only be able to achieve the data transfer speeds that its Ethernet port supports.
Note: The cnlab Speedtest for measuring speeds > 1 Gbit/s will be available from Q2/2020. The maximum speed that can be measured by an external speed test is 2.3 Gbit/s with an Internet-Box 3 connected to the 2.5 Gbit/s port with an Ethernet cable. When uploading and downloading simultaneously, the speed may be limited to 6 Gbit/s.
