The proliferation of mobile broadband networks is increasingly making personal devices like smartphones the preferred choice for content consumption. As the content quantity and quality increase, the load on available cellular spectrum resources also grows, causing congestion and degradation of the user experience. This creates an opportunity to offload live and popular content from a very large number of unicast streams to only a few broadcast/multicast streams using “Direct-to-Mobile” (D2M) broadcast delivery as part of the 5G fabric.
In a country with a large population and spectrum scarcity, offloading to D2M broadcast distribution dense urban as well as rural areas is a good option. Current 3GPP broadcast standards, however, are derived from short-frame low latency unicast standards and perform poorly for long-frame broadcasts. ATSC 3.0 is a purpose-built broadcast standard with excellent performance for pedestrian and mobile use cases. This talk will present the ATSC 3.0-based D2M solution and discuss results from our proof-of-concept trial in Bangalore, India.
