AT&T officially launched its LTE network in Denver and Milwaukee on Wednesday, bringing substantially higher wireless data speeds to iPhone 5 customers in those markets. The carrier also turned on LTE service this week in Daytona Beach, Louisville, York, Provo-Orem, and Tacoma.
AT&T said its LTE data network offers operates up to 10 times faster than 3G and in areas where The Mac Observer has been able to test performance, data speeds are noticeably faster compared to 3G.
The official launch of LTE in the new markets came on Wednesday, but at least in Denver we were seeing LTE coverage on Tuesday. The coverage areas seemed to be somewhat limited with reliable signals along the I25 corridor south of Westminster, and parts of the southeastern and southwestern metro area. We weren't, however, seeing reliable LTE signals in Boulder.
AT&T plans to continue expanding its LTE market, adding "Customers can get 4G speeds outside of 4G LTE areas on our 4G HSPA+ network, unlike competitors, where smartphone customers fall back to slower 3G technologies when outside of LTE coverage."
