Rare AT&T 4G Spotting: Detroit
We’ve been having a difficult time tracking down AT&T’s supposed 4G network, as has the vast majority of Atrix 4G and Inspire 4G owners. The lack of HSUPA support on these devices mean that data speeds actually benchmark worse than 3G devices. Nevertheless, AT&T’s 4G HSPA+ network, which is only available in places with “enhanced backhaul” (for which there exists no coverage map), has been spotted in Detroit, as you can see in the below video. YouTube user lopertit6 was able to clock a pretty impressive 4.8mbps down in one run of the SpeedTest.net application on his Atrix 4G. Unfortunately, the corresponding upload speed was a mere 200kbps.
If you’re able to track down AT&T’s 4G network, please send us a video of your device running the SpeedTest.net application and let us know where you found the 4G!
