A study conducted recently by network technology firm Arieso showed that Android users move more data over cellular networks than any other group of smartphone users. The study mentions high-resolution cameras along with video recording and sharing capabilities as being among Android’s biggest bandwidth hogging features. Due to Android’s rapid growth, carriers find themselves struggling to keep up with the ever-increasing congestion on their networks. “Smartphone subscriptions are rising and so too is subscriber appetite for mobile data. It’s a trend that’s set to continue,” Arieso CTO Michael Flanagan told Reuters. The move to next-generation “4G” network technologies like WiMAX and LTE will help carriers accomodate the demand for data, but rolling out these new networks takes a tremendous amount of time and resources. Sprint began lighting up its WiMAX network last year but coverage is still very limited, and Verizon Wireless just flipped the switch on LTE in 38 cities, though it currently does not offer any LTE-compatible cell phones. AT&T and T-Mobile will not begin rolling out LTE until next year.
