BGR noted during our hands-on look at the LG Nitro HD that AT&T’s next-generation 4G LTE network has gone live in New York ahead of launch, and it looks like another market has gone live as well: Phoenix, Arizona. Our speed tests Thursday night on AT&T’s fledgling 4G LTE network were nothing to scoff at — we saw nearly 7Mbps down and about 9Mbps up — but AT&T subscribers in Phoenix will be excited to learn that early speed test results reveal blistering download speeds up to 40Mbps and upload speeds in excess of 10Mbps. Read on for more.
The screenshot above, supplied to BGR by a reader, was captured Thursday night outside Phoenix on a Samsung Galaxy S II Skyrocket. The same reader also confirmed that speed tests performed on his Samsung Galaxy Tab 8.9 tablet reached download speeds of 40Mbps. These speeds, while impressive, may not be an accurate indication of network performance once 4G LTE service from AT&T launches in Phoenix.
AT&T has yet to confirm official launch dates for its 4G LTE networks in New York or in the Phoenix area.
