T-Mobile is working quickly to roll out its LTE network. It appears that they are beginning to test installations in a few different cities and OpenSignal has seen their app utilized on the new 4G LTE installations. Lucky for us, we have some early testing data on the network that show it should be able to compete.
A quick disclaimer before we actually dive into the hard numbers: these tests were carried out with little load on the network and were likely in strong signal locations. With that said, the T-Mobile LTE came up with an average download speed of 25Mb/s and 8Mb/s upload. Combine that with an average ping of 40ms and it starts to look really good. Of course, real world speeds will be slower.
It's also interesting to note that the network was being tested with the Samsung Note II, Samsung Galaxy S4, an unlocked AT&T Galaxy S3, and the SII HD LTE. OpenSignal says they have detected testing in Seattle, Denver, Las Vegas, New Orleans, New York, San Diego, Kansas City, and the San Jose/Bay Area.
