How Does the Suddenlink Speed Test Work?

The speed test sends a small amount of data to and from your device. This data exchange measures the time the information travels between your device and the server. The test calculates the download speed by measuring how quickly data is transferred from the server to your device. 

Similarly, the Suddenlink Communications speed test calculates upload speed by the speed data travels from your device to the server. Latency, often called ping, is when a data packet travels to the server and back. A lower latency value indicates a more responsive connection.

Factors of Suddenlink Speed Test: Download Speed, Upload Speed, and Latency

The broadband speed test measures three key factors that collectively determine the quality of your internet:

Download Speed: 

It measures the rate at which data is transferred from the internet to your device. It directly impacts your ability to stream videos, download files, and browse websites quickly.

Upload Speed: 

Upload speed evaluates how fast data travels from your device to the internet. It’s essential for activities like sending emails, uploading files, and participating in video conferences.


Latency reflects the delay between the sending and receiving of data. Low latency is optimum for online gaming, video conferencing, and real-time communication. It should not exceed 200 milliseconds, as it shows that your broadband connection is slower.
