Starlink – measurements of data throughput over the first few months

Since spring of this year, we have installed a Starlink standard antenna firmly and flatly on the roof of our motorhome and operate it without the original Starlink router via the 24V DC on-board voltage and the Teltonika RUT X11 router in the living cabin. We have already described this in several articles, see above all Starlink - Fixed installation of the standard antenna (Part 2) and Starlink - operation on 24V DC (part 2). This setup has been working stably for several months now and to our complete satisfaction. If the antenna mounted on the roof has a clear view of the sky, there is usually a good internet connection. So far we have only experienced restrictions on the connection in very bad weather with heavy rainfall. At irregular intervals we carry out measurements of the data throughput to the Internet via Starlink, which we would like to publish here.

Here is a summary of the most important information about our structure:

• Starlink contract: “Mobile Regional” with billing address in Germany
• Starlink antenna: “Standard” (modified, permanently mounted flat on the vehicle roof)
• Locations: Germany, Netherlands, Switzerland, Italy, Poland, Austria, France – see details https://www.polarsteps.com/AllradWohnmobil
• Router: Teltonika RUT X11, connected to the Starlink standard antenna on the WAN side via Ethernet cable
• Data throughput measurement: https://www.speedtest.net/
• Current browser: Firefox 119.0.1
• Current operating system: Ubuntu 22.04.3 LTS
• PC hardware: Lenovo ThinkPad T480S, connected via Ethernet cable to the LAN side of the Teltonika RUT X11
• No measurements were taken during precipitation (e.g. rain or snow).
• All measurements were carried out with the vehicle stationary

Here is a chart with all previous measurement results:

And here are the measurements themselves:

Summary of the measurement results:

• When downloading, our setup typically achieves values of > 100 Mbps, sometimes significantly more. The peak was just over 300 Mbps.
• When uploading, we typically achieved values of > 10 Mbps, sometimes significantly more. The peak value was >30 Mbps.

Comments on the measurements:

• Between August 15th and September 11th, 2023, due to technical problems with the Teltonika RUT X11 router, a replacement router was used that only supported 100Mbps on the WAN and LAN side - therefore the measured values are lower during this period.
