New Report from RootMetrics Includes Data on Sprint’s LTE Rollout in Dallas

“This is our first test of Sprint’s new LTE technology in this market, and it was eye-opening to see how their network performed.”
- Bill Moore

RootMetrics™ announced today the latest Dallas RootScore™ Report and corresponding RootScore Awards. Complementing consumer-generated results from the RootMetrics CoverageMap app, the RootMetrics scout team professionally tests how mobile carriers perform in cities across the country. The Dallas report analyzed results from 40,800 data, call, and text tests on the AT&T, MetroPCS, Sprint, T-Mobile, and Verizon networks using smartphone technology RootMetrics designed to replicate real-world mobile usage.

RootMetrics has previously scouted Dallas three times: February and September of 2011, and most recently in February of 2012.

Sprint launched LTE service in Dallas and fourteen other markets in July 2012.

“This is our first test of Sprint’s new LTE technology in this market, and it was eye-opening to see how their network performed,” said Bill Moore, CEO of RootMetrics.

Observations Since Previous Test in Dallas
With the implementation of LTE by Sprint, RootMetrics took a close look for changes in Sprint’s performance. Sprint delivered an average upload speed that was 1.3 Mbps faster than RootMetrics’ previous visit, jumping from 0.8 Mbps to 2.1 Mbps; their average download speed was comparable to the speed RootMetrics recorded earlier in 2012.

AT&T’s LTE network delivered similar average speeds for both download and upload when compared to RootMetrics’ previous visit. This is the second consecutive win for AT&T in both the combined and data categories.

Verizon’s LTE network delivered a similar average upload speed, while, their average download speed decreased slightly.

Which Carrier Ranks First in Dallas?    
RootMetrics sorted the test results in order to share with consumers which carrier provided the fastest and most reliable data network, which carrier had the fewest blocked and dropped calls, and which carrier offered the fastest text service.

•Data Performance: The RootMetrics data performance tests analyzed how fast each carrier’s network was able to download and upload files and how often a customer could successfully connect to a data network.

AT&T’s LTE network delivered a 1st place performance in all data speed measures, with a blistering average download speed of 17.2 Mbps and an average upload speed of 8.6 Mbps. Verizon’s LTE network placed second, with a speedy 11.4 Mbps average download speed and an average upload speed of 5.8 Mbps.

Although T-Mobile does not offer LTE service, their HSPA +42 network delivered an average download speed of 8.0 Mbps and an average upload speed of 1.4 Mbps.

Sprint’s LTE network delivered a 4th place performance in average speed for both download and upload, though RootMetrics expects Sprint’s data speeds to improve as their network expands.

MetroPCS trailed all carriers in average download speed.

•Dallas High Speed Data Comparison and Potential Slowdowns:
The standard for what constitutes LTE or “4G” speed is debatable, but looking at the consistency with which a carrier offers speeds greater than 5 Mbps gives a good indication of a “4G” experience. In order to give consumers a more complete picture of how the carriers performed in Dallas, RootMetrics compared how often carriers recorded speeds greater than 5 Mbps.

The following details the percentage of tests that each carrier recorded download speeds above 5 Mbps:
o    AT&T 82.9%
o    Verizon 80.2%
o    T-Mobile 63.1%
o    Sprint 22.4%
o    MetroPCS 13.2%

Sprint recorded the greatest percentages of download and upload speeds below 1.5 Mbps, doing so in 64.0% and 68.1% of tests, respectively.

•Data Reliability: Verizon placed first with a 98.0% success rate in data reliability.

•Call Performance: RootMetrics analyzed call performance by measuring both dropped calls and blocked calls (the inability to place an outgoing call). Although the race in Dallas was close, Verizon won first place in the call category through statistical differentiation; moreover, Verizon did not record a single blocked call.

•Text Performance: RootMetrics compared how long it took each carrier to receive a single text message. Verizon recorded the fastest overall receive time (3.4 seconds), and delivered texts in less than 10 seconds 85.5% of the time. Sprint did so 52.5% of the time.

•Overall: Verizon recorded 1st place results in all categories in Dallas. The final results are:
1 – AT&T (101)
2—Verizon (88)
3 – T-Mobile (70)
4 – MetroPCS (63)
4 – Sprint (62)

The August 2012 Dallas RootScore Report is the latest in an ongoing series of performance measurement reports and corresponding RootScore Awards from RootMetrics. The company will continue to publish additional reports for U.S. wireless markets to help consumers make better decisions about the right carrier for his or her individual needs.

To evaluate the mobile experience in the Dallas area, RootMetrics conducted 40,800 call, data, and text tests during a seven-day period, covering all hours of the day and night, August 7 – August 13, 2012. The tests, which mimic real-world mobile behavior, were conducted using the RootMetrics CoverageMap app running on Android-based, off-the-shelf consumer smartphones purchased from carrier stores in Dallas. To ensure that testing aligns with the consumer experience, and to provide each carrier with the chance to rate as highly as possible, RootMetrics utilizes the most advanced smartphones available at the time of testing. Tests are conducted on activities that consumers perform most often: making phone calls, uploading and downloading files from the Internet, and sending and receiving texts.

Consumers who are interested to see how their network coverage performs compared to other carriers can download the free RootMetrics Cell Phone CoverageMap app for iPhone or Android devices.

Mobile performance varies depending on where people live, work, or otherwise spend time.

The results of this report, combined with the geographical coverage maps at and via the Cell Phone CoverageMap app, allow people to make better decisions about the right carrier for their individual needs.
