Verizon Earns 7th Consecutive Top Overall Mobile Performance Award in Detroit

RootMetrics® (Globe Newswire) - 13 May 2016

Rankings close; T-Mobile picks up awards for Network Speed and Data Performance

BELLEVUE, Wash (GLOBE NEWSWIRE) -- RootMetrics®, the standard for independent mobile performance information, reveals Verizon is the Overall Performance RootScore Award winner for the seventh consecutive testing period in Detroit. In total, the carrier took first place – outright or shared – in four of the six categories measured, according to the 1st Half 2016 Detroit Metro RootScore Report. This included wins in Network Reliability, Call Performance, and Text Performance.

In the remaining categories, T-Mobile led the way with outright wins in Network Speed and Data Performance, both of which Verizon previously held outright. According to RootMetrics, an IHS (NYSE:IHS) company, AT&T also rose the top, sharing first place in Call Performance with Verizon, as well as Text Performance with Verizon and T-Mobile.

"While Verizon continues its overall mobile performance reign in Detroit, mobile consumers have a number of strong options depending how they use their phones what they consider to be most important," said Julie Dey, RootMetrics vice president. "T-Mobile took the lead in both Network Speed and Data Performance categories, while Verizon came out on top for Network Reliability which is considered essential to a good mobile experience."
This is the tenth time RootMetrics has tested the mobile networks in Detroit and issued its findings for the metro area. RootScore Reports provide a scientific, independent, consumer-focused assessment of mobile network performance.

2 – T-Mobile (97.3)

RootScores are on a scale of 0 to 100. A good Overall RootScore means strong all-around performance and a good consumer experience.
Mobile Performance You Can Depend on
Reliability and speed are crucial to a consistently good mobile experience. RootMetrics indicates performance in these key areas with its Network Reliability category, a combination of results from data, call, and text tests; and its Network Speed category, which examines results across testing of data transfers, downloading email, and web/app tasks.

Verizon earned first place outright in Network Reliability for the fourth consecutive testing period in Detroit; however, the rankings were extremely close with less than two points separating first and last place. Meanwhile, T-Mobile took the lead in Network Speed, an award Verizon previously held for two consecutive periods.

Network Reliability rankings:
1 – Verizon (99.5)
2 – AT&T (98.4)
2 – T-Mobile (98.2)
2 – Sprint (97.6)
Network Speed rankings:
1 – T-Mobile (95.8)
2 – Verizon (95.0)
3 – AT&T (85.0)

Data Performance
Data Performance RootScores reflect how well networks perform in downloading and uploading data, performing email tasks, and downloading files that approximate loading typical webpages or apps.
In Data Performance, T-Mobile was the outright winner, while Verizon was close behind. Verizon recorded the fastest median download speed at 31.3 Mbps, meaning it would take about two seconds to download a song. Meanwhile, T-Mobile recorded the fastest median upload speed at 23.1 Mbps; at that speed it would take less than two seconds to upload a picture on the network.
