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
