4G Internet speed test
Internet speed tests will give you an upload speed and download speed.
Uploading refers to the process of transferring data from your computer to the Internet, and downloading refers to transferring data from the Internet to your computer.
Usually the download speed is much greater than the upload speed (ADSL).
This is usually OK because for most people they download much more than they upload.
Download speed tests work by transferring a file of a known size from a test server located on the Internet to your computer, and measuring how long it takes.
A 4 MB file will take 2 secs over a 16 Mbits/s link and 8 seconds over a 4 Mbits/s link..
The upload speed is measured by uploading a file from your PC to the test server and again measuring the time taken.
