# Speedchecker Bandwidth Measurements
This data call provides bandwidth measurement results collected on the Speedchecker platform. The bandwith is measured with HTML5 clients (e.g. https://www.broadbandspeedchecker.co.uk (opens new window)) as well as with Speedchecker's mobile applications. The unit of measurement is kilobits per second (Kbps).
Since 2018-05-28 data is synchronized live between Speedchecker and RIPEstat, which means that every measurement done on the Speedchecker platform will show up in this data call after a few seconds.
