A recent User Experience Study released by Spirent Communications, a global leader in test and measurement, showed that Telefonica O2, a leading digital communications company with over 23 million customers on its 2G, 3G and 4G networks, took 1st and 2nd rankings across many quality measurements on 4G voice and data services in Britain.
The study, which was commissioned by Telefonica O2 was based on over 47,000 calls and 170,000 data tests made during the period May to July this year. The quality measurements were made using Spirent's user experience analytics systems and iPhone 5c devices purchased at retail stores by Spirent. Telefonica O2 was benchmarked against the performance of 3 other operators in the country and the results are as follows:
(1) the measured call completion success rate among all operators was comparable, ranging from 98.8% to 99.0%, with no operator exhibiting a statistically relevant difference relative to other operators,
(2) the web browsing speeds for Telefonica O2 on the 5 tested websites ranked 1st out of 4 measured networks at an average time of 2.7 seconds, with the lowest ranked network at 3.4 seconds,
(3) the file download speeds for Telefonica O2 and one other network were jointly ranked 1st out of 4 measured networks with average speeds of 11.3 Mbps and 11.6 Mbps, respectively, and with the lowest ranked network at 6.4 Mbps (the difference between the top 2 measured networks was not statistically meaningful, leading to a joint ranking),
(4) the file upload speeds for Telefonica ranked 1st out of 4 measured networks at an average speed of 5.5 Mbps with the lowest ranked network at 3.0 Mbps,
(5) the web browsing success rate for Telefonica O2 ranked 2nd out of 4 measured networks at 97.9%, with the highest ranked network at a 98.6% success rate and the lowest ranked network at 96.4%,
(6) the file download success rate for Telefonica O2 ranked 2nd out of 4 measured networks at 98.6%, with the highest ranked network at a 99.5% success rate and the lowest ranked network at 97.4%,
(7) the file upload success rate for Telefonica O2 ranked 1st out of 4 measured networks at 99.2%, with the lowest ranked network at 97.6%.
"Our goal is to provide the industry with an independent and accurate view of the user experience. To ensure accuracy, we only use real, unmodified devices for our user experience measurements – the same devices consumers purchase in retail stores. We measure the key factors that matter to users like the ability to make calls and browse to web sites and we do it all with a statistically rigorous sampling methodology. Our customers appreciate that we don’t just provide independent measurement services – we also give them the ability to perform their own measurements and analysis with our suite of user experience analytics systems.”
