RootMetrics out of Bellvue, Washington is a group of people just like us. They understand how smartphones have become an integral part of our everyday lives. Over the past few years, RootMetrics has evolved from a testing mobile carriers' signals in select metropolitan areas, to a service that gauges mobile carriers' coverage and signal strength across the country.
RootMetrics does their testing using real-world scenarios, such as placing calls, downloading files, email retrieval, and text send and receiving. The tests are run from random locations using both indoor and outdoor scenarios from the same location. They will then perform the tests while driving to the next location. In addition, RootMetrics also runs tests inside the fifty busiest airports in the nation. This would include BWI, which was ranked twenty-second in 2013.
RootMetrics primarily tests three key areas of the four major mobile carriers, data, call, and text performance, using a sliding scale of 0 - 100. They accomplish this using unmodified off the shelf Android phones purchased from each of the major mobile carriers. RootMetrics does not alter the phones in any way, shape or form. This gives them the same level of performance we can expect from our mobile carriers. It is one of the most comprehensive reports judging the mobile industry.
RootMetrics released their first half 2014 report yesterday, naming Verizon Wireless the overall winner across the nation. The company tested Baltimore on May 5, and found some interesting results. In the data performance category, Verizon garned a score of 96.8, barely edging out T-Mobile and AT&T, who came in with 96.5 and 96.4 respectively. Sprint trailed badly at 82.5. In call performance, Verizon Wireless opened up their lead somewhat, scoring 99.0 to T-Mobile's 97.6. AT&T 96.8, and Sprint again trailed badly at an abysmal 77.3. In text performance, T-Mobile led the way, squeaking past AT&T at 96.4 to 95.9. Verizon Wireless slipped to third at 95.2, and Sprint did better at 94.3, though still coming in last.
RootMetrics Reliability Index placed Verizon Wireless at the top with a 99.2 ranking, while T-Mobile and AT&T ranked tied for second at 98.4. Sprint again brought up the rear with an 87.4. In speed, T-Mobile led the pack with a 92.2 ranking, followed by Verizon Wireless at 91.5. AT&T placed third at 90.6, and Sprint again came in last with a 67.1 rating.
In a nutshell, Baltimore's mobile carriers showed very well, with the exception of Sprint. The distance in scoring between first and third was fairly tight. In the coming days we are going to delve into some of RootMetrics' more obscure findings. In the meantime, there is a RootMetrics app available through Google Play Store if you would like to do your own testing.
