Verizon and T-Mobile Deliver Fastest Data Speeds in Washington, D.C.
Data RootScores factor in each network’s reliability and speed when downloading and uploading data, performing email tasks, and handling files that represent elements of a webpage. Verizon won the Data RootScore Award in Washington, D.C., and recorded the fastest median download speed at 14.4 Mbps. T-Mobile’s median download speed of 13.2 Mbps trailed that of only Verizon, but its median upload speed of 17.8 Mbps was much faster than the upload speeds recorded by the other networks.
Median download and upload speeds by network
T-Mobile: 13.2 Mbps download/17.8 Mbps upload
Verizon: 14.4 Mbps download/5.8 Mbps upload
AT&T: 9.7 Mbps download/4.0 Mbps upload
Sprint: 4.6 Mbps download/1.7 Mbps upload
Data speeds affect 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 the nation’s capital should be a smooth experience on any of the four networks. Verizon, AT&T, and T-Mobile led the charge and shared the Call RootScore Award in a three-way tie, with scores of 99.1, 98.7, and 98.4, respectively. Sprint ranked fourth with a score of 86.9.
AT&T won the Text RootScore Award with a score of 97.2, but with Text RootScores above 94 for all four networks, text performance was strong across the board.
More than 50,000 tests in Washington, D.C.
To evaluate the mobile experience in Washington D.C., RootMetrics conducted 50,928 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 March 24 - 31, 2014. The tests were conducted using the RootMetrics RootScout app running on Android-based, off-the-shelf consumer smartphones purchased from carrier stores. Tests were conducted indoors (at 84 locations) and outdoors during drive tests (covering 2,005 miles). For details about the results, see the methodology section of the RootMetrics website. Mobile performance varies depending on where people live, work, or otherwise spend time. Because a variety of factors can influence performance, examples that list what data speeds mean while performing various mobile activities are a general look at data speeds for illustrative purposes and aren’t specific to Washington, D.C.
