Thousands of Data, Call and Text Tests Lead to a Verizon Victory in New York

RootMetrics RootScore Report New York - Call Failures

RootMetrics™, the first independent service to measure mobile experience from a consumer’s point of view, announced today the results of the New York RootScore™ Report and corresponding RootScore Awards. This comprehensive report ranks Sprint, T-Mobile, AT&T and Verizon on call, data and text performance. Due to the strong results on Verizon’s LTE network, it received the highest combined score of 89.7 out of a possible 100. T-Mobile (61.9) ranked second. Sprint (48.4) was third and AT&T (39.4) ranked last.

“Each of the major carriers touts 4G coverage in New York, but similar to our other market tests, we observed that not all 4G technology is the same,” said Bill Moore, CEO of RootMetrics. “We’re focused on giving people a true idea of how the major carriers are performing to let consumers make better decisions about the right carrier for their individual needs.”

Are All 4G Networks in New York Created Equal?
To evaluate the New York Metro Area (defined as the Urbanized Area for New York - Newark according to the U.S. Census Bureau), RootMetrics performed thousands of call, data and text tests during a seven day period, covering all hours of the day and night, in June 2011. The tests centered on activities that consumers perform most often: making phone calls, uploading and downloading files from the Internet, and sending and receiving texts.
•Data Performance: In New York, Verizon’s LTE network led all carriers in every element of data performance testing. Verizon’s data network delivered download speeds over twice as fast as T-Mobile, the second fastest data network, and over three times as fast as both Sprint and AT&T. Verizon’s upload speeds were twice as fast as T-Mobile and AT&T and nearly five times as fast as Sprint.

Although each carrier delivered high speeds during the testing, the percentage of time that high speeds were delivered varied significantly. Sprint delivered download speeds of less than 500 kbps 44 percent of the time. RootMetrics observed that AT&T delivered download speeds of less than 500 kbps 22 percent of the time, T-Mobile 18 percent and Verizon 14 percent. Conversely, Verizon delivered speeds above 10 Mbps 42 percent of the time, compared to less than 1 percent by AT&T.
•Call Performance: In New York, Verizon received the fewest blocked and dropped calls during testing, and as a result, the carrier is the winner of the RootScore Award for Call Performance. While blocked calls were lower than rates observed in other metropolitan markets where RootMetrics has performed measurement, dropped calls in the New York metro area are another story. With the exception of Verizon, all carriers dropped more calls in the area than the average dropped call rate RootMetrics measured for each carrier in previous markets.

AT&T’s dropped call rate was significantly higher than any other carrier. Based on RootMetrics testing, AT&T’s network is three times more likely to drop a call than when using T-Mobile’s network, nearly five times more likely to drop a call than on Sprint’s network, and nearly 26 times more likely to drop a call than when using the Verizon network.

  • Text Performance: In a series of tests to measure how long it takes to send or receive a text message (SMS), RootMetrics observed that T-Mobile is faster than other carriers and is the winner of the RootScore Award for Text Performance. In New York, T-Mobile customers were nearly two times more likely to receive a text within 10 seconds than any other carrier. Sprint was the slowest carrier to send a text to a number within its own network. Sprint’s network took over one minute to send texts nearly 20 percent of the time.

•Overall: RootMetrics has developed an algorithm that incorporates the results for Call, Data and Text Performance measurements into a combined score. In New York, due to the strong results on Verizon’s LTE network, it is the recipient of the RootScore Award – Combined for New York.

The New York RootScore Report is the tenth in a series of performance measurement reports and corresponding RootScore Awards from RootMetrics. Earlier reports covered Seattle, Dallas, Washington, D.C., Miami, Chicago, Houston, Los Angeles, Atlanta and Boston. The company will continue to publish additional reports on U.S. wireless markets to help consumers make better decisions about the right carrier for their individual needs. The next report will feature San Francisco.

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 Coverage Map Apps allow people to make better decisions about the right carrier for their individual needs.
