Independent Review of Mobile Voice and Data Services Commissioned by Telefonica O2
Sunnyvale, Calif. – August 12, 2014 – Spirent Communications, the leader in user experience analytics for mobile devices and services, has completed a study of the user experience of 4G mobile services in 20 major cities across England, Scotland and Wales. The study, commissioned by Telefonica O2, included over 47,000 calls and 170,000 data tests over a three month period from May to July. Key elements of user experience were measured including call completion, data session completion, web browsing speed and file download/upload speed. All measurements were performed using Spirent’s user experience analytics systems and iPhone 5c devices purchased at retail stores by Spirent.
Key findings from the study, aggregated across all cities, included: (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%.
