Verizon Retains Its Overall Mobile Performance Lead in Los Angeles

BELLEVUE, Wash., Dec. 18, 2015 (GLOBE NEWSWIRE) -- Verizon won the Overall Performance award in Los Angeles for the fourth consecutive time according the latest report from RootMetrics®, the standard for independent mobile performance testing. In the 2nd Half 2015 Los Angeles Metro RootScore Report, Verizon also won outright in Network Speed and Data Performance, while sharing awards across all other categories tested, including Network Reliability, Call Performance and Text Performance. Furthermore, the carrier recorded the fastest speeds in all of Los Angeles.

While Verizon swept the rankings, the other carriers aren't far behind in most categories. In the Overall Performance category, AT&T and T-Mobile tied for second place, falling only about two points behind the winner. Furthermore, AT&T shared the top spot with Verizon in Network Reliability, while all carriers earned excellent scores above 97.0. The latest testing from RootMetrics, an IHS (NYSE:IHS) company, also revealed shared wins in both Call and Text Performance.

"Verizon won our Overall Performance RootScore Award outright for the fourth consecutive time in Los Angeles," said Julie Dey, RootMetrics vice president. "However, the other carriers are showing strong performance across most categories, with all four earning excellent scores above 97.0 in Network Reliability and shared first-place wins in three of the six categories tested. This means mobile consumers in Los Angeles can expect reliably good performance when it comes to most everyday mobile tasks."

This is the ninth time RootMetrics has tested the mobile networks in Los Angeles and issued its findings for the metro area. RootScore Reports provide a scientific, independent, consumer-focused assessment of mobile network performance.
