RootMetrics Tests 4G Networks in Dallas, Results Show AT&Ts LTE Tops Verizons LTE Network

  (March 21, 2012)

Bellevue, WA (PRWEB) March 21, 2012

RootMetrics, the first independent service to measure mobile experience from a consumers point of view, announced today the latest Dallas RootScore Report and corresponding RootScore Awards. This is RootMetrics third report on mobile carriers performance in Dallas. After analyzing results from more than 26,000 real-world data, call and text tests, RootMetrics found significant changes compared to prior reports.

Since the last Dallas RootScore report in October 2011, AT&T introduced LTE service and the Dallas market provided another opportunity for RootMetrics to evaluate how AT&T and Verizon are performing in the ongoing race for LTE superiority. In markets where both Verizon and AT&T have introduced LTE networks, RootMetrics test results have shown the two carriers jockeying back and forth for the position as the fastest data network. In Dallas, AT&T emerged as the clear data speed victor: their LTE service beat Verizons LTE network for both upload and download speeds by a hefty margin. RootMetrics will continue to compare the LTE performance of Verizon and AT&T whenever possible.

Also new to this report, RootMetrics was able to test T-Mobiles network with a device enabled for HSPA+42 service and T-Mobiles download speeds were significantly faster than the previous report in October. In addition, RootMetrics was able to include scoring for MetroPCS in this latest report. RootMetrics will continue to test and add regional carriers whenever possible to provide the most complete picture of mobile performance.

With recent network and device upgrades, the mobile landscape in Dallas has changed dramatically and consumers continue to ask the question, Which network is best? said Bill Moore, CEO of RootMetrics. With this new report, were looking at the impact of those upgrades on consumer experience to help people get a clearer picture of which carrier works best for their mobile habits.

Which Carrier Did Best in Dallas?    
To evaluate the Dallas area, RootMetrics conducted more than 26,000 call, data and text tests during a seven-day period, covering all hours of the day and night, from February 21-27, 2012. The real-world tests were conducted using the RootMetrics CoverageMap app running on off-the-shelf, Android-based consumer smartphones from carriers stores. Tests centered on activities that consumers perform most often: making phone calls, uploading and downloading files from the Internet, and sending and receiving texts.

The resulting RootScore Report reveals which carriers provided the fastest data network (AT&Ts LTE swept the category), which carrier had the fewest dropped calls (a tie between Verizon and AT&T) and the fastest network for sending and receiving texts (a draw, with AT&T, T-Mobile and Verizon too close to call). AT&Ts strong performance across the board led to an easy overall victory in Dallas, earning a score of 94.8 out of 100. Verizon (86.4) came in second place, with MetroPCS (56.3), T-Mobile (50.9) and Sprint (45.4) tied for third.    

  •     Data Performance: The RootMetrics data performance tests analyzed how fast each carriers network was able to download and upload files and how often a customer could successfully connect to the data network. Though Verizons data speeds improved on what were already impressive numbers, AT&T swept the data category in Dallas, offering the fastest average and maximums for both download and upload speeds. At 17.2 Mbps, their average download speed quadrupled what RootMetrics measured in October, while their 9.0 Mbps upload speed was more than 9 times faster than what was measured in the last report. AT&T recorded download speeds above 5 Mbps in 83.5 percent of RootMetrics tests, edging ahead of Verizons 82.2 percent mark.

T-Mobiles HSPA+42 emerged as the clear third-place network for download speeds, though it trailed AT&T and Verizon on average by more than 12 Mbps and 8 Mbps, respectively.

Verizon offered the most reliable data network in Dallas, recording a failure in only 2 percent of tests.

  •     Call Performance: Call performance continues to be strong in Dallas. All five carriers delivered statistically equal performances, resulting in a draw. Verizon and MetroPCS delivered a perfect performance in the dropped call category, resulting in a 0.0 percent failure rate.
  •      Text Performance: AT&T, Verizon and T-Mobile delivered statistically equal performances in Dallas.
  •      Overall: With a strong showing in all three categories, Verizon took the top spot in the combined standings for Los Angeles. The final results are:
1 Verizon (94.8)
2 AT&T (86.4)
3 MetroPCS (56.3)
3T-Mobile (50.9)
5 Sprint (45.4)
