Fastest Data Speeds Lead to Hands-down Victory for Verizon in Los Angeles

RootMetrics

RootMetrics™, the first independent service to measure mobile experience from a consumer’s point of view, announced today the results of the Los Angeles RootScore™ Report and corresponding RootScore Awards. This comprehensive report ranks AT&T, Sprint, T-Mobile, and Verizon on call, data and text performance. Due to the strong results in each of these categories, Verizon received the highest combined score of 88.4 out of a possible 100. T-Mobile (51.3) and Sprint (47.4) had a statistical tie for second place and AT&T (42.9) ranked last.

“With all of our testing, we’re looking for the answers to questions that consumers are asking every day – which carrier has the fastest network? Who has the fewest dropped calls? Which one will send or receive texts the quickest?” commented Bill Moore, CEO of RootMetrics. “These RootScore Reports, combined with our detailed coverage maps, allow people to get a true idea of how the carriers are performing and then make better decisions about the right carrier for their individual needs.”

The Fastest and Most Reliable Network in Los Angeles
To evaluate the Los Angeles market (defined as the Los Angeles 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 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: Hands down, Verizon’s LTE network delivered the fastest data speeds in the area. Coupled with its strong network reliability, Verizon was the clear leader in the data category. RootMetrics recorded download speeds on average nearly 3 times faster than the second-fastest download network (Sprint) and up to 6 times faster than the second-fastest upload network (AT&T). RootMetrics also found that Verizon’s LTE network was the most reliable in Los Angeles, successfully connecting to the data network nearly 96 percent of the time. Conversely, T-Mobile’s network measured a data success rate of only 89 percent.

Los Angeles was the first market that RootMetrics measured after the release of AT&T’s HUSPA firmware update. So far, upload speeds with the new update are nearly 10 times higher than speeds measured in other markets reported in previous RootScore Reports.

Interestingly, maximum data speeds in Los Angeles were the fastest RootMetrics has observed in any market to date (Seattle, Dallas, Miami, Washington, D.C., Chicago and Houston).

•Call Performance: Across the board in both blocked calls and dropped calls, RootMetrics observed lower rates in Los Angeles than in other local markets covered in previous reports. However, Verizon came out on top when it came to the fewest call failures and was the winner of the RootScore Award – Call. During the measurement, RootMetrics experienced call failure on AT&T’s network three percent of the time, nearly three percent of the time on T-Mobile’s network, nearly two percent of the time on Sprint’s network, and less than 0.5 percent of the time on Verizon.

•Text Performance: Median text delivery times amongst the four carriers ranged from 6.6 seconds (T-Mobile) up to 15.3 seconds (AT&T). T-Mobile was awarded the RootScore Award – Text for Los Angeles. T-Mobile’s network delivered texts to customers within its own network between two times to 14 times faster than other carriers were able to send texts within their own network. Sprint was the slowest to deliver texts to a number within its own network. Also, the Sprint network sent the most texts in over one minute.

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

The Los Angeles RootScore Report is the seventh in a series of performance measurement reports and corresponding RootScore Awards from RootMetrics. Earlier reports covered Seattle, Dallas, Washington, D.C., Miami, Chicago and Houston. 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 Atlanta.

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