What factors have an effect on the result?

Several factors have a significant influence on the test result. The main ones are:

  • the contractually agreed maximum bandwidth of your mobile Internet access (e.g. speed throttling (download/upload) depending on the chosen tariff and/or after exceeding a specific volume included in the monthly base fee)
  • the bandwidth utilisation of your Internet provider
  • the device you are testing with
  • the operating system of the device and its configuration
  • simultaneous use of the same connection by other users or programs (e.g. filesharing, updates)

If LAN is used:

  • the quality of your LAN router (e.g. NAT throughput)

If WLAN is used:

  • the distance between the WLAN router and your device
  • the quality of your WLAN router (e.g. supporting 802.11ac or 802.11ax)
  • If mobile services are used:
  • the technology used (2G/EDGE, 3G/UMTS/HSPA, 4G/LTE, 5G/NR)
  • the quality of service at your location (signal strength, depending on the device)
  • whether you are inside or outside a building
  • how fast you are moving (e.g. lower data transmission rates on the motorway or in the train)
  • the number of users sharing the base station with you
