cnlab Speed Test

CNLAB SPEED TEST
Evaluate your mobile data rate and review the performance of your private internet connection through WLAN. Compare your measurements on the device or on the web and find performance issues using the visual preparations and stored connection information.

MOBILE PERFORMANCE BENCHMARKING SYSTEM
cnlab develops and operates the Mobile Performance Benchmarking (MPB) system for private use and Internet Service Providers. The MPB client application, used to measure Key Performance Indicators (KPI) such as Up- and Download or Roundtrip Times to reference systems, are available for iOS, Symbian, Android and Windows Phone. The measured speed depends not only on the operators network, but also on the amount of customers within the local network cell or the overall performance of the used device.

PRIVACY
Each device gains a unique identification number (UserID) so that each user can view its own results via Web browser. For each UserID not only the performance data are stored but also a set of system data (e.g.: IP or device ID) as well as administrative data (user location). The UserID is never given away. Its only use is to trace bugs, boost performance or create SpeedTest statistics. When an error is reported, some user send personal information, such as their E-Mail, name, address or phone number. These private data are only send to cnlab and the addressed Service Provider from the error report.

FURTHER INFORMATION
Caused by a limitation of Android, it is not possible to fetch information about the current active Internet connection while the screen is off. To counter this, the App is now waking the device (again), when a measurement is running. This forced us to add the permission "prevent phone from sleeping".
We are well aware, that this has a negative impact on the battery, but as long as Android has this limitation, there is no other way.
Thank you for comprehension.
