Data Performance: Verizon wins second consecutive Data RootScore Award in Los Angeles
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. Verizon won the Data RootScore Award outright in Los Angeles for the second consecutive time, scoring a 98. Notably, Verizon has won or shared this award seven consecutive times. Verizon recorded the fastest median download speed at 27.3 Mbps. T-Mobile and Verizon recorded the fastest median upload speeds at 17.5 Mbps and 18.2 Mbps, respectively.
Since previous testing in February, there were several notable changes to the data performance landscape in Los Angeles. Sprint's rate of download and upload tests recorded on LTE increased from approximately 48 percent in February to approximately 84 percent in this latest round of testing. Subsequently, Sprint's median download speed increased from 1.5 Mbps to 8.9 Mbps. T-Mobile's median upload speed increased from 14.6 Mbps to 17.5 Mbps. Verizon's median download speed increased from 16.3 Mbps to 27.3 Mbps, and Verizon's median upload speed increased from 9.2 Mbps to 18.2 Mbps.
Median download and upload speeds by network
Verizon: 27.28 Mbps download/18.23 upload
T-Mobile: 13.69 Mbps download/17.50 upload
AT &T: 9.84 Mbps download/8.00 upload
Sprint: 8.89 Mbps download/2.69 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 Los Angeles should be a positive experience on any of the four networks. Verizon, T-Mobile, and AT &T shared the Call RootScore Award, each with scores above 96. Sprint followed with a score of 94.2. In February, Verizon won this award outright.
AT &T won the Text RootScore Award, with a score of 97.4. With Text RootScores of 96 or higher for all four networks, texting in Los Angeles should be a smooth experience.
