The AT&T 4G LTE speeds guessing game is unofficially over. Late last week we began hearing reports of the LTE icon popping up in the notification bars of AT&T's three compatible smartphones--the Samsung Galaxy S II Skyrocket, HTC Vivid, and LG Nitro HD.
So, I fired up Ookla's Speedtest.net app to test diagnostics (for ping, download, and upload speeds) on two compatible phones we have in-house, the Nitro HD and the Vivid.
What speed sampling would be complete without caveats? Since the LTE network is a soft-launch and nothing official or necessarily widespread, since the app scores are not the final word in real-world performance, and since this is not intended to be a scrutinized comparison between AT&T and any other network, consider the Speedtest.net results a diagnostic suggestion, with more in-depth testing to come after AT&T cuts the red ribbon on LTE.
With that said, the speeds look promising at their fastest, mostly sticking to the 14 or 15Mbps range for downloads, with spikes into the 30Mbps range and a rock-bottom outlier of just 0.75Mbps.… Read more
