Video is expected to contribute ~70% of all the mobile traffic in 2018*. LTE Broadcast is the most efficient mechanism to distribute the same content to many users, and is an important solution to address the 1000x data challenge. Initially focusing on venue casting, LTE Broadcast can address many other media distribution such as software updates and breaking news. The evolution of LTE Broadcast makes it dynamic and more scalable, and in the long term, takes it even beyond mobile as a solution for next generation terrestrial TV.

LTE Broadcast evolving and going beyond mobile
Aug 25, 2014
LTE Broadcast was commercially launched in Jan 2014, powered by Qualcomm® Snapdragon™ processors integrated with Qualcomm® Gobi™ modems. LTE Broadcast is gaining global momentum, with many operators trialing and announcing launch plans.
LTE Broadcast is supported across Snapdragon processor tiers and Gobi modems, and comes coupled with highly optimized service layer middleware that has been interoperability-tested with major infrastructure vendors.
Venue casting is the most common use case, but there are many other use cases for efficient distribution via LTE Broadcast: Smartphone OS/software updates, breaking news, delivery of e-media, music/audio broadcasting, and even public safety applications. For all these use cases, LTE Broadcast can offload data from unicast, significantly improve the user experience and create new revenue opportunities for mobile operators.
The evolution of LTE Advanced brings in features such as dynamic switching between unicast and broadcast, higher capacity and flexibility to enable new use cases, such as targeted ad insertion.
The evolution with the dynamic switching also makes LTE Broadcast more scalable, so that it can be utilized more often, at more places, across the network, for more applications.
Small cells improve coverage in venues, especially in areas hard to reach by a macro network, thereby improving the overall capacity and user experience. They also localize the broadcast capacity and free-up the macro network.
Small cells can also utilize the bandwidth-rich 5GHz unlicensed spectrum and offload venue traffic from licensed spectrum.
As part of ongoing effort in Europe to define the next generation of terrestrial broadcast TV, LTE Broadcast is being considered as a candidate technology.
LTE Broadcast provides ~2x efficiency** than today’s DVB-T technology and is a cost-effective solution to offer converged services to both mobile and fixed devices. This is an excellent example of LTE Advanced expanding into new frontiers
