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

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).
