More Than 40,000 Real-world Data, Call and Text Tests Show Differences in Carrier Performance in the Rose City

RootScore Report - Portland Combined Scores

The information from our reports empowers consumers to make better decisions about the best carrier for their mobile habits.

RootMetrics™, the first independent service to measure mobile experience from a consumer’s point of view, announced today the results of the Portland RootScore™ Report and corresponding RootScore Awards. This comprehensive report analyzes results from more than 40,000 real-world data, call and text tests and ranks Sprint, T-Mobile, AT&T and Verizon on their performance. The data reveals which carrier provided the fastest and most reliable data network (Verizon), which carrier had the fewest dropped and blocked calls (Verizon, again) and which carrier has the fastest text service (T-Mobile). Due to the strong showing in both data and call tests, Verizon’s LTE network received the highest combined score of 87.4 out of a possible 100. There was a statistical tie for second place between T-Mobile (51.6), AT&T (50.4) and Sprint (46.4).

“As we continue our testing in markets across the U.S., we’re working to provide consumers with a true picture of the major carriers’ 4G performance. In Portland, similar to other markets, results show that 4G performance across carriers varies,” said Bill Moore, CEO of RootMetrics. “The information from our reports empowers consumers to make better decisions about the best carrier for their mobile habits.”

Which Carrier Performed Best in Portland?    
To evaluate the Portland metro area, RootMetrics conducted more than 40,000 call, data and text tests during a seven day period, covering all hours of the day and night, from August 1-7, 2011. The real-world tests were conducted using off-the-shelf Android-based consumer smartphones and 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: The RootMetrics data performance tests analyze how fast each carrier’s network was able to download and upload files, and how often a customer could successfully connect to the data network. Verizon’s LTE network offered both the fastest and also the most reliable data service in the Portland area. Verizon’s data network delivered download speeds 3.8 times faster than the next fastest carriers (Sprint and AT&T). And Verizon’s upload speeds were 7.2 times faster than the next fastest carrier (AT&T).
Verizon also recorded average download and upload speeds that were faster than the maximum download and upload speeds of the other carriers. Verizon hit speeds above 10 Mbps almost 70 percent of the time. Regarding accessibility, RootMetrics tests showed that Sprint had the most data failures, registering a failure in 9.44 percent of the tests.

•Call Performance: When it comes to call performance in Portland, all four carriers delivered statistically equal performances, resulting in a draw.

•Text Performance: RootMetrics performed a series of tests to determine how long it takes to send or receive a text message (SMS) from each carrier. After winning first place in the text category in every single market RootMetrics has tested in 2011, T-Mobile continued its winning streak in Portland. AT&T had a strong showing in Portland, recording faster median text times than RootMetrics has typically observed in other markets. Verizon recorded the slowest median text delivery times overall and the second slowest time for delivering a text to a phone within a carrier’s own network.

•Overall: Due to the strong results on Verizon’s LTE network for data and call performance, it is the recipient of the RootScore Award – Combined for Portland.
