RootMetrics Report Ranks Mobile Performance in Miami, Names Verizon the Top Scoring Carrier

  (May 09, 2011)

Bellevue, Wash. (PRWEB) May 09, 2011

RootMetrics, the first independent service to measure mobile experience from a consumers point of view, announced today the results of the Miami 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 Verizons LTE network, it received the highest combined score of 77.7 out of a possible 100. AT&T, T-Mobile and Sprint had a statistical tie for second place.

At RootMetrics, we developed a new way to measure mobile performance that reflects the consumers true experience, said Paul Griff, CEO RootMetrics. When we look at the results, and see how carriers can vary depending on location, along with when you use the network and how you use your phone, its clear that there isnt a one-size-fits-all carrier. One person may value data speeds above call performance. Another may rely most heavily on texting. These reports, combined with our detailed coverage maps, allow people to make better decisions about the right carrier for their individual needs based on the metrics that matter to them.

How the Carriers Measure Up In Miami
To evaluate the Miami market (defined as the Miami Urbanized area 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 April 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.

  •     Call Performance: Throughout the measurement, each carriers call performance was statistically even. However, the report shows that in Miami people are three times more likely to drop a call on the Sprint network than with any other carrier.
  •     Data Performance: In Miami, the ability to access a data network proved problematic for all carriers except AT&T. T-Mobile delivered the highest rate of data failure of 18 percent. This was followed by failure rates for Sprint at 17 percent and a nine percent data access failure rate for Verizon. AT&Ts data network proved to be the most reliable, measuring failure rates of just over two percent.


When it comes to speed, Verizon clearly delivered the fastest data speed of any network. On average, Verizons (LTE) network delivered download speeds approximately two times faster than Sprints (WiMAX) or T-Mobiles (HSPA+21) networks. Upload speeds on Verizon were even faster, delivering speeds more than four times as fast as T-Mobile and nearly seven times faster than Sprint. In sharp contrast to the 4G speeds measured in Miami, data speeds on AT&Ts 3G network were significantly slower than the competition.

  •     Text Performance: AT&T and T-Mobile delivered speeds on average in less than 30 seconds, with a significant portion of texts delivered in less than 10 seconds. These relatively short text delivery times led both AT&T and T-Mobile to tie for the award in the Text category. Sprint and Verizon delivered texts on average in over 30 seconds.
  •     Overall: RootMetrics has developed an algorithm that incorporates the results for Call, Data and Text Performance measurements into a combined score. In Miami, due to the strong results on Verizons LTE network, it is the recipient of the RootScore Award Combined for Miami.

The Miami RootScore Report is the third in a series of performance measurement reports and corresponding RootScore Awards from RootMetrics. Earlier reports covered Seattle and Dallas. The company will publish additional reports on U.S. wireless markets to help consumers make better decisions about the right carrier for their individual needs.

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 http://www.rootmetrics.com or via the Cell Phone Coverage Map Apps for iPhone or Android allow people to make better decisions about the right carrier for their individual needs.
