RootMetrics previously visited Denver in May 2014. The two carriers also shared the #1 rank for network reliability and data performance. AT &T joined Verizon and T-Mobile for the top rank in call performance. That's according to independent mobile analytics firm RootMetrics®, which measures mobile performance of the four major national carriers with tests designed to replicate real-world consumer behavior.

Data Performance: Verizon and T-Mobile Deliver Fastest Data Download Speed in Denver

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 and T-Mobile shared the RootScore Award for data performance in Denver, with scores of 95.3 and 94.9, respectively. The two carriers also recorded the fastest median download speed at 10.32 and 10.52 Mbps, respectively. T-Mobile recorded the fastest median upload speed at 7.69 Mbps.

Since previous testing in May, Sprint officially launched LTE in the area. Subsequently, Sprint's median download speed increased from 0.83 to 6.78 Mbps, and Sprint's median upload speed increased from 0.71 Mbps to 4.41 Mbps. By contrast, and despite occupying the top ranking for data performance, T-Mobile's median download speed decreased from 17.06 to 10.53 Mbps since May. And T-Mobile's median upload speed decreased from 10.54 to 7.69 Mbps in that same time.

Median download and upload speeds by network

T-Mobile: 10.53 Mbps download/7.69 upload
Verizon: 10.32 Mbps download/5.42 upload
AT &T: 7.36 Mbps download/3.64 upload
Sprint: 6.78 Mbps download/4.41 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 Denver should be a positive experience on any of the four networks. Verizon, AT &T and T-Mobile shared the RootScore Award for call performance for the third consecutive time. Their scores were 98.6 (Verizon), 97.3 (AT &T) and 97.3 (T-Mobile). Sprint ranked fourth, with a score of 93.9.

Text me

T-Mobile won its second consecutive RootScore Award for text performance, with a score of 96.6. With Text RootScores above 93 for all four networks, texting in Denver should be a smooth experience.

More than 25,000 tests in Denver

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 Denver.
