The careful analysis of speed test measuring data enables us to make statements on the performance of internet service providers, terminal device types or network technologies.


Users of the Speedtest apps can analyze their own results in the cnlab-evaluation platform and compare them to other options - neutrally and independently of their own ISP.


The cnlab Speedtest apps are available free of charge. They measure download and upload speeds as well as response times from your own device (PC, notebook, tablet or smartphone) with reference systems on the internet.
