Smartphone owners in the United Kingdom are relying upon Wi-Fi more than 3G for wireless Internet access, according to a recent study by Nielsen. The analytics firm said owners of smartphones based on Google's Android operating system transfer 78 percent of their Internet content over Wi-Fi. Nielsen Smartphone Analytics employed on-device metering to show that offloading from the cellular network to Wi-Fi increases each hour every evening, and peaks between 11 p.m. and midnight, at which time 90 percent of data transferred is via Wi-Fi. "3G data transfer tends to peak just before the working day starts, again at lunchtime and finally during the early evening commute when users cannot rely so much on a Wi-Fi connection," said Nielsen.
