RootMetrics™, the first independent service to measure mobile experience from a consumer’s point of view, announced today the latest Las Vegas RootScore™ Report and corresponding RootScore Awards. This is the second RootMetrics report on mobile carriers’ performance in Las Vegas. The report analyzes results from over 10,000 real-world data, call and text tests on the AT&T, Cricket, MetroPCS, Sprint, T-Mobile and Verizon networks. RootMetrics found significant changes compared to its prior testing in Las Vegas.

Since the last time RootMetrics visited Las Vegas in November 2011, the most significant change was AT&T’s LTE network upgrade and the dramatic impact it had on their data speeds: AT&T’s average download speed increased from 3.3 Mbps to 16.2 Mbps, while their average upload speed increased from 1.2 Mbps to 5.4 Mbps.

Verizon and AT&T are battling for 4G supremacy in markets across the country where RootMetrics has performed tests, and in Las Vegas the two networks came out neck and neck. AT&T recorded faster average download, maximum download, and maximum upload speeds, though the two carriers offered similar results when comparing average upload speed. RootMetrics will continue to compare the LTE performance of Verizon and AT&T whenever possible.

Though not as fast as either AT&T or Verizon, T-Mobile emerged as the clear runner-up to these two LTE carriers. Both T-Mobile and Verizon recorded faster average download speeds this visit compared to testing in November.

With a high 18.6% data failure rate, Cricket was the least reliable carrier in Las Vegas. They also lagged far behind all the other carriers in data speeds.

RootMetrics will continue to test and add regional carriers whenever possible to provide the most complete picture of mobile performance.

“While multiple carriers promote 4G coverage in the Las Vegas area, consumers are left wondering which carrier is truly the fastest and which one is the most reliable,” said Bill Moore, CEO of RootMetrics. “We’re hopeful that this report, along with our coverage app, will help people make better decisions about the right carrier for their individual needs based on the metrics that matter to them.”

Which Carrier Did Best in Las Vegas?
To evaluate Las Vegas, RootMetrics conducted over 10,000 call, data and text tests during a five-day period, covering all hours of the day and night, from March 13-17, 2012. The real-world tests were conducted using the RootMetrics CoverageMap app running on off-the-shelf, Android-based consumer smartphones from carriers’ stores. Tests 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 analyzed 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.

AT&T’s average download speed was a blistering 16.2 Mbps, with Verizon close behind with a 13.7 Mbps average. Verizon recorded speeds above 5 Mbps in 84.7% of tests, while AT&T surpassed the 5 Mbps mark 81.9% of the time.

T-Mobile’s HSPA+42 service might be a good choice for those looking for fast speeds but not ready to make the move to LTE, with an average download speed of 7.2 Mbps.

With an average data failure rate of only 1.4 percent, AT&T proved to be the most reliable in Las Vegas.

•Call Performance: Call performance continues to be strong in Las Vegas. As in the first round of testing in 2011, all carriers delivered statistically equal performances, resulting in a draw. AT&T did not drop any calls during our testing, while Verizon did not record any blocked calls.

•Text Performance: Verizon and AT&T shared the top spot in the text category with strong performances, including overall receive times of 3.4 and 3.9 seconds respectively.

•Overall: With a strong showing in all three categories, AT&T and Verizon split the top spot in the combined standings for Las Vegas. The final results are:
1. AT&T
1. Verizon
3. T-Mobile
4. MetroPCS
4. Sprint
4. Cricket
