High-quality video bogging down wireless networks

Video usage statistics for wireless networks reveal that consumers are beginning to demand increases in video quality, which has ramifications for managing network capacity.

The statistics were compiled by Bytemobile, a company that specializes in optimizing the quality of experience (QoE) on wireless networks. Bytemobile's goal is to remind potential customers of the value of its services; the findings are still instructive for anyone with a multi-screen video delivery service or anyone providing wireless backhaul services.

Highlights from the report include:

  • Wireless networks need to support video demand not only during peak traffic hours, but at all hours of the day.
  • Video generates 40 to 60 percent of total mobile data traffic on wireless networks.
  • Laptops, iPhones/iPads and Android devices consume the majority of mobile video today. Half of the total data traffic that is generated by these devices is from video.
  • On average, users are requesting high-resolution videos 29 percent of the time; however, that percentage of videos is responsible for 45 percent of total traffic on the network.
  • Subscribers that access the YouTube website via a mobile browser are served higher-resolution videos than subscribers accessing the same videos through the pre-installed YouTube application, regardless of the network or device type.
  • Dependent on network conditions and time of day, mobile videos stall between 5 and 40 percent of the time. Video optimization technology reduces stalling by 30 to 50 percent.
  • Subscribers on wireless networks optimized for video consume double the mobile video content than those on un-optimized networks.
