Data Performance: AT &T wins Data RootScore Award in Dallas
Data Performance RootScores factor in each network's reliability and speed when downloading and uploading data, performing email tasks, and downloading files that approximate using typical webpages or apps. AT &T won the RootScore Award for data performance in Dallas, with a score of 97.9. AT &T recorded the fastest median download speed at 20.7 Mbps, while T-Mobile recorded the fastest median upload speed at 14.5 Mbps.
Since previous testing in March, AT &T's median download speed increased from 12.1 Mbps to 20.7 Mbps. In that same time, AT &T's median upload speed increased from 9.6 Mbps to 13.5 Mbps. Meanwhile, Sprint's median download speed increased from 2.6 Mbps to 10.5 Mbps, and Sprint's median upload speed increased from 0.9 Mbps to 5.7 Mbps. T-Mobile's median upload speed increased from 7.4 Mbps to 14.5 Mbps. Also noteworthy since the last testing period, Verizon deployed its Advanced Wireless Spectrum (AWS) in the area.
Median download and upload speeds by network
AT &T: 20.73 Mbps download/13.54 upload
T-Mobile: 13.81 Mbps download/14.52 upload
Verizon: 13.63 Mbps download/6.92 upload
Sprint: 10.52 Mbps download/5.70 upload
Data speeds impact how quickly consumers can perform various tasks online. For example, in an ideal situation, uploading medium-sized pictures (1 MB) to Facebook or other online albums typically takes 25 seconds to 45 seconds on average at speeds below 3.0 Mbps. At speeds above 6.0 Mbps, uploading a similar picture generally takes less than 1 second.
Making the call
Making calls in Dallas should be a positive experience on any of the four networks. Verizon and AT &T shared the RootScore Award for call performance, each with scores of approximately 98.8. Sprint and T-Mobile, meanwhile, weren't far behind, sharing the third-place ranking with scores of 96.9 (Sprint), 96.3 (T-Mobile).
AT &T and Sprint shared the RootScore Award for text performance, with scores of 97.4 and 97.2, respectively. This marks the first time that Sprint has won or shared the Text RootScore Award in Dallas. With Text RootScores of 96 or higher for all four networks, texting in Dallas should be a smooth experience.
Nearly 75,000 tests in Dallas
To evaluate the mobile experience in Dallas, RootMetrics conducted 74,045 call, data, and text tests on the networks of AT &T, Sprint, T-Mobile, and Verizon during all hours of the day and night from November 16 through November 22, 2014.
