First up is a tool you can use on your laptop or desktop that tells you upload and download speeds along with measuring latency and jitter. You have to provide some info the FCC before you can run the test and the site alternates between testing via Ookla or MLAB.
Of course there have been tools to measure this around for awhile. Speedtest.net is the one I use the most on both my iPhone (yes, there’s an app for that) and also on computers of all stripes.
