Telecommunications network for Baden-WürttembergTelecommunications network for Baden-Württemberg

We create the networks for your data communication.

In Baden-Württemberg and worldwide.

terranets bw not only operates a comprehensive gas transmission network, but also a highly powerful communications infrastructure. Gas transmission is optimally controlled and monitored using our own fibre optics network.

And as an infrastructure provider, we also offer this to our customers – for connecting and efficiently operating our customers´ telecommunications.

Your benefits with terranets bw

Our plus in security:
With us, your data transmission is safe

Operating and building gas pipelines require the highest possible security standards. As a customer of our telecommunications network, you also benefit from this expertise. Because, for a start, our fibre optics network is located in our protective strip – an especially protected and secured area along our gas transmission system.

This means our fibre optics network infrastructure provides extremely high operational and failure security. And secondly, our pipeline network is permanently monitored, for example with regular network inspections from the air and on-site inspections along the pipeline routes. This is how we guarantee the highest possible protection for our networks.

Our driving force:
To strengthen our region economically

Providing high-speed internet throughout the whole of Baden-Württemberg is a decisive, economic factor for the future development of cities and communities – also far away from large urban areas.

Fast and redundant data connections with the highest levels of security are also essential for utility companies and regional energy companies. Both with regard to attractive, new business developments with resident business and industrial enterprises as well as for business and industrial parks.

As an infrastructure provider, we are investing in future-proof high-speed connections for Baden-Württemberg with our fast and flexible fibre optics network.

Test your data speed

4,8 Mbit/s


Your upload speed reaches only 13% of the speed of our product terraconnect.

1,2 s


Your PING time is 0,4.

Repeat speedtest

The bandwidth of your internet connection can never be determined with 100 % accuracy as too many other factors influence the assessment. This includes, for example, the processor load of the measuring server and your current network utilisation. The measurement results can also deviate depending on the end device.

The connection type, for example WiFi or Bluetooth, can also influence the result. Please ensure that you do not access any other websites or download any files during the test. Close any background programs such as email or other web browsers to prevent interference during the test.
