  • ATSC 3.0 Backward Compatible SFN In-Band Distribution Link and In-Band Inter-Tower Wireless Network for Backhaul, IoT and Datacasting - $15

    Date: April 26, 2020
    Topics: ,

    Last year, we presented a ATSC 3.0 backward compatible in-band backhaul system. In this paper we will present the field measurement results that support the viability of the in-band backhaul system implementation using full-duplex transmission. We further present a full duplex Inter-Tower Communication System ? a re-configurable wireless network for SFN broadcasting, in-band inter-tower communications, and IoT/datacasting applications, while backward compatible with the ATSC 3.0.

    (1) SFN Broadcasting:

    Improve service quality for mobile, handheld, and indoor receptions;
    Allow new services: IoT, connected car, datacasting;
    One-to-many timely services for large rural areas for traffic map update, weather conditions, emergency warning.

    (2) In-band Distribution for SFN

    Eliminate studio-to-tower link spectrum requirement;
    Reduce broadcast operating costs;
    Spectrum sharing and re-use.

    (3) Inter-Tower Wireless Network

    Scalable & reconfigurable network embedded in a broadcast system;
    Broadcast network cue & control that do not rely on other telecom infrastructure ? surviving emergency and nature disaster;
    Backhaul data services among towers: IP-based IoT, and wide-area datacasting;
    Each tower can broadcast localized content in its coverage area (TDM/LDM);
    Inter-Tower Network can work under SFN, OCR, or Multi-Frequency Network environments;
    Full-Duplex Transmission: Transmitting and receiving on the same frequency ? improving spectrum efficiency;
    Dynamic Spectrum Re-Use and Sharing + LDM: Converging Broadcast and Wireless Broadband Services.

    This session will be rebroadcast on the?BEIT Express?channel?on May 13, 2020?at 9:15 p.m.?and May 14, 2020 at 5:15 a.m.?EDT (UTC -4).
