A new report from RootMetrics
by IHS Markit, the standard for mobile performance benchmarking, reveals
T-Mobile and Verizon deliver the top overall performances in Miami.
T-Mobile, however, continues to lead Miami in the increasingly important
data performance category. In the latest 1st
Half 2019 Miami Metro RootScore Report, T-Mobile takes outright
awards in network speed and data performance and shares the wins for
overall performance and text performance.
At 16.6 Mbps,T-Mobile records the fastest median upload speed in the
Miami metro area, allowing a subscriber to upload a picture to social
media in mere seconds. Meanwhile, AT&T records the fastest median
download speed at 28.2 Mbps.
“T-Mobile continues to deliver impressive performance in Miami,” said
Francis Sideco, vice president, technology at IHS Markit. “However, the
other carriers are making noise too, with Verizon leading in network
reliability and AT&T offering the top median download speed. It’s a
competitive market and such balanced performance is good news for
consumers, especially as demands for data-heavy communication increases.”
This is the 16th time RootMetrics has tested the mobile networks in
Miami and issued findings for the metro area. RootScore Reports provide
a scientific, independent and consumer-focused assessment of mobile
network performance.
Mobile Performance You Can Depend On
Verizon earns the Network Reliability RootScore Award outright, which
the carrier previously held in a tie with T-Mobile. Meanwhile, T-Mobile
takes the award for network speed outright for the second report in a
row. Reliability and speed are crucial for a consistently good mobile
experience. The RootMetrics network reliability category considers a
combination of results from data, call and text tests, while the network
speed category examines results across testing of data transfers and
web/app tasks.
Data Performance
T-Mobile holds the Data Performance RootScore Award outright for the
second consecutive report. While AT&T records the fastest median
download speed at 28.2 Mbps, it trails in median upload speeds and in
data reliability. In addition to testing speeds overall, RootMetrics
also collects performance information during outdoor walking tests in
the dense urban core of Miami. In this testing, AT&T recorded the
fastest median download speed at 33.4 Mbps and T-Mobile recorded the
fastest median upload speed at 23.1 Mbps. The data performance category
reflects how well networks perform in downloading and uploading data,
and downloading files that approximate loading typical webpages or apps.
Call and Text Performance
AT&T and Verizon share the award for call performance, which was
previously held in a three-way tie with AT&T, Verizon and T-Mobile.
Additionally, all four carriers share the Text Performance RootScore
Award. Call performance testing is based on how reliably each network
can place and maintain calls, while text performance measures how
reliably and quickly consumers can send and receive text messages.
Comprehensive Testing
To evaluate the mobile experience in Miami, RootMetrics conducted tests
across all hours of the day and night from March 16 through March 26.
Using smartphones purchased off the shelf at carrier stores, tests were
conducted indoors at 123 locations and while driving 2,385 miles. For
details about RootMetrics testing, see the methodology
section of the RootMetrics website.
