hustling to get that 4G LTE network up and running ahead of schedule? AT&T has been ranked worst among the four major wireless carriers in the U.S. according to the J.D. Power and Associates U.S. 2011 Wireless Network Quality Performance Study. The major nationwide study tested overall network performance for the four major U.S. cell phone service providers as well as top regional carriers from around the country. Among the big four — Verizon Wireless, AT&T, Sprint and T-Mobile — Verizon Wireless found itself atop the list in each of the six regions where J.D. Power performed its tests. On the other end of the spectrum, AT&T was either last or tied at the bottom in five out of the six regions. Read on for more.
In the North Central, Southeast and Southwest regions, AT&T tied for last place with Sprint. In the Mid-Atlantic region, AT&T sat in a three-way tie behind Verizon Wireless, and AT&T was alone at the bottom in the Northeast region. In the Southwest, the only region where AT&T was not found to be at the bottom, the carrier tied Sprint for second-best performance while Verizon sat at the top and T-Mobile was ranked worst. “Based on the varying degree of consistency with overall network performance, it’s critical that wireless carriers continue to invest in improving both the voice quality and data connection-related issues that customers continue to experience,” said Kirk Parsons, senior director of wireless services at J.D. Power and Associates. J.D. Power ranked network performance in 10 key areas for this study: dropped calls; calls not connected; audio issues; failed/late voicemails; lost calls; text transmission failures; late text message notifications; Web connection errors; email connection errors; and slow downloads.
