The most prevalent type of video on wireless networks worldwide continues to be user-generated content available on YouTube and Google Videos, according to a report released today by Bytemobile.

Bytemobile, which specializes in video optimization solutions, anonymously sources the quarterly aggregate data traffic in a global cross-section of its customers’ networks to provide a glimpse into the current state of the mobile ecosystem. The most current report is based on third-quarter data.

On a per-user average, iPhone users generate more video traffic than Android device users. But the peak hours of data traffic on wireless networks have shifted from daytime to evening, signifying a transition in mobile data consumption from business usage to residential entertainment-based usage, according to the company.

Higher-resolution video is requested significantly less often than lower-resolution video yet generates a similar amount of the total data traffic on the network – 31 percent compared to 39 percent, according to the report. That indicates that even a small increase in the number of users consuming higher-quality video – which is expected on higher-speed networks – will generate a considerably greater network traffic load.

In a statement, Bytemobile Vice President of Product Management Joel Brand said that while the results were not surprising, the findings in the third-quarter Mobile Minute Metrics report indicate that this is just the beginning of video’s impact on wireless networks. He says video optimization is an essential tool in the operator’s arsenal for managing the growth while ensuring a quality experience for end users.

Bytemobile also announced the general availability of its new Unison Mobile Internet Platform, which includes new media caching capabilities.
