How to read this DSL coverage map?
The map above shows the percentage of buildings in a given area that are covered by a copper telephone cable connection. The areas are divided into square parcels measuring 250 x 250 meters, with a color scale ranging from red (low coverage) to green (maximum coverage). Areas without color indicate the absence of buildings or missing data provided by internet operators.
What types of copper-based connections are available?
The main types of copper-based connections are:
ADSL (Asymmetric Digital Subscriber Line):Â Asymmetric speed, better suited for downloading.
VDSL (Very-high-bit-rate Digital Subscriber Line):Â Higher speeds than ADSL due to advanced technologies.
SDSL (Symmetric Digital Subscriber Line):Â Symmetrical speeds for both downloads and uploads, typically used in business environments.
ISDN (Integrated Services Digital Network):Â Used for telephony and data, now obsolete in Switzerland.
What are the pros and cons of a DSL connection?
The following table summarizes the main advantages and disadvantages of a DSL connection:
Pros | Cons |
Widely available, even in rural areas. | Lower speeds compared to fiber connections. |
Generally cheaper than fiber optic. | Signal sensitivity to the distance from the central office. |
Compatible with existing telephone lines. | Higher likelihood of signal interference. |
How fast is a copper connection?
The download speed of a copper connection depends on the technology used: typically, an ADSL connection can reach up to 20 Mbps download speeds, while a VDSL connection can achieve up to 300 Mbps.
However, actual speeds depend on the distance between the router and the central office, as well as the quality of the installed cables.
With this information in mind, you can move on to the comparison section and find the subscription that suits you best.
