Effective connection type (ECT) refers to the measured network performance, returning a cellular connection type, like 3G, even if the actual connection is tethered broadband or WiFi, based on the time between the browser requesting a page and effective type of the connection.
The values of '
3g', or '
4g' is determined using observed round-trip times and downlink values.
|ECT||Minimum RTT||Maximum downlink||Explanation|
||2000ms||50 Kbps||The network is suited for small transfers only such as text-only pages.|
||1400ms||70 Kbps||The network is suited for transfers of small images.|
||270ms||700 Kbps||The network is suited for transfers of large assets such as high resolution images, audio, and SD video.|
||0ms||∞||The network is suited for HD video, real-time video, etc.|
