Your Logo Motivation for Broadcast-Broadband Convergence
• Video traffic is growing exponentially • By 2023 , >70% of mobile traffic will be
video
• Video consumption is inversely proportional to education • Rural areas and lower education sections
could consume highest video
• Unicast networks not designed to carry broadcast video • Serious congestion in mobile networks
• Analytics show 80-20 rule in the type of video traffic
• Pull to push architectures • AR/VR, OTT
• Connected cars and ADAS makes it worse ! • Imagine millions of cars needing a fat pipe
• Ola is already issuing a RFP for connecting their cars
• Cost per bit of unicast to broadcast is huge
• Large swathes of UHF spectrum lying unused • Per TRAI estimates DD spectrum is worth
100B$
• Auctioning spectrum is not the answer • Leads to monopolies and lack of innovation
• Monetize the spectrum through pay/use

Your Logo What is convergence ?
• Use the unused broadcasting spectrum to offload video and live event traffic
• A converged intelligent network that directs video intelligently to a “overlay” broadcasting network
• Multiplex the network by providing a supplemental downlink channel
• Components of a Converged network • A intelligent EPC and network that monitors and analyses traffic to
direct it to appropriate network
• A converged UE device that has a broadcasting tuner and modem

Your Logo Additional Use cases
• Emergency alerting systems
• Bulk firmware updates
• IoT Broadcast networks perform the complementary function of enabling actuators from the centralized cloud ( e.g. lighting streetlamps, starting irrigation pumps etc. )
• Accurate timing distribution • Enables secure communications, Synchronization of telecom and IoT nodes
• Opportunistic Offloading of Unicast traffic on the DTT network
• Efficient scheduling may allow mixed traffic - SFN based broadcast and non-SFN based unicast in the same frame
