How Does the Xfinity Speed Test Work?

The internet speed test Xfinity identifies your location to find the closest server. It forwards a small amount of data from your device to the server, and then the server sends it back. The speed checker estimates the time it takes to exchange data between the server and your device. It then gives you the round-trip duration in milliseconds. This is the latency of your broadband.

Next, the speed test makes numerous connections with the internet server and seeks some data. The Xfinity Wi-Fi speed test downloads the data on your device. It calculates the downloading time to give you your broadband’s download pace in megabits per second.

Similarly, the test finds out the internet’s upload speed in Mbps by measuring the time it takes data to transfer from your device to the internet server.
