A report by 4G Americas on Supporting Wireless Video Growth and Trends discusses the video traffic growth trends, chalenges and solution to deliver it over mobile networks.
"One of the largest growth areas for mobile data traffic is mobile video and it is also the greatest user of network capacity," stated Chris Pearson, President of 4G Americas. "Mobile video traffic is already more than 50 percent of mobile data traffic for some service providers, and further growth could soon strain the wireless network resources due to finite and limited spectrum availability."
In the report, particular emphasis is given to the technology features that will enable successful delivery of mobile video to the masses, including:
- -Optimizing the radio and core networks (HTTP Adaptive Streaming, etc.)
- -Support of multiple network architectures (Het-Nets, LTE broadcast, content delivery networks)
- -Support of client optimizations, and
- -Enhanced codecs (HEVC)"
Throughput to individual users varies with time and location, based upon cell load and proximity to the cell. The broad range of emerging devices requires flexibility in video delivery to address variations in screen sizes, screen resolution of end user devices, and impact of video usage on battery life. It is therefore critical to minimize wireless congestion due to video traffic, by tailoring the video application to the underlying network resources and device types, while still maximizing end user experience." - Gautam Talagery, Director, Mobile Broadband Solutions at Ericsson
