The Challenge of HD Video Streaming on LTE

Friday, April 22nd, 2011

One of AT&T’s non-redacted arguments in support of its acquisition of T-Mobile USA is that data usage on AT&T’s network is projected to “skyrocket by a factor of eight to ten” over the next five years due in part to streaming HD video. AT&T’s vision is that T-Mobile’s resources would be used to relieve resulting capacity restraints.

Enabling an HD streaming service will be challenging because of the relatively-high and somewhat-constant bit rates required in a fading radio environment. Wondering how practical this is, I recalled a paper Motorola prepared last year reporting some of its simulation results on mobile broadband streaming video.
