Mobile Video Hiccups Once Second Out of Every Six

Despite the protestations of network neutrality advocates, there's a very good reason why real-time services ranging from voice to conferencing to entertainment video actually require some form of optimization and even packet prioritization.

Recent data collected in mid-year 2010 by Bytemobile from networks operated by the likes of AT&T, China Mobile, China Telecom, KDDI, KPN, O2, Orange, Orascom, Sprint Nextel, T-Mobile, Telecom Italia Mobile, Telefónica, TeliaSonera and Vodafone show that every minute of mobile video consumed by end users includes about 10 seconds of stalling.

That's 17 percent of every minute of video, or a stall every six seconds. That is hugely disruptive of viewing experience and will not be acceptable once users become accustomed to using video content. It will be completely unacceptable once users start paying for video content services.

The problems currently are worse about 10 p.m. local time, and best at 5:30 a.m,, says Bytemobile. Expecting such congestion and disruption, most mobile users opt to watch videos at lower-quality settings to improve their media experience. That probably isn't what content owners or their business partners prefer, to say nothing of mobile service providers who will inevitably be tarnished by that sort of performance.

Nor does "more bandwidth" solve such problems. Bytemobile data shows that stalling occurs on even the fastest of networks and a quality user experience requires optimization of video content. In other words, packet prioritization and, or, other measures to keep latency and jitter performance optimal.

That said, as network bandwidth decreases, video stalling dramatically increases.

Consumption of high-definition video is nearly non-existent on wireless networks, at 0.07 percent of video-specific traffic volume.

Moreover, video traffic directly impacts bandwidth availability on wireless networks all over the world.
