Demand for data services is leading to increased failings on mobile networks, according to recent research conducted by Actix. The number of dropped data sessions and voice calls has increased by 121 percent as data demand grows.
On average around 1 percent of voice and data calls fail on mobile networks however some locations deliver call failure rates of over 17 percent during periods of high network load.
Stressed mobile networks are exposing the variation in the quality of the network connections across handset brands, with the worst devices dropping, on average, more than 2.5 percent of all calls and data sessions. iPhones generally performed better than average on data and Blackberry devices were least likely to drop a voice call.
iPhone 3GS recorded the lowest percentage of dropped data sessions, followed by the iPhone 5 and 4s. The best voice performer was the Blackberry 9320, with the Galaxy range of devices (S2, S3, S3 mini and S4) dropping significantly more calls than competitors - in some cases up to 2.5 percent of all calls and data sessions.
