Sinclair Broadcast Group, Inc., Nexstar Media Group, Inc., and Univision Local Media, Inc. have reached an agreement with the leading wireless and broadcast infrastructure provider, American Tower Corporation to jointly construct and operate Single Frequency Network (SFN) sites to broadcast Advanced Television Systems Committee (ATSC) 3.0 signals within the Dallas Designated Market Area (DMA), as a first step toward a national launch. The SFN will allow for the testing, validation and deployment of advanced next generation broadcast services, which will provide many benefits to consumers, including dramatically improved over-the-air reception, immersive audio, deep-indoor reception, mobile reception, zoned programming/advertising, automotive services and advanced emergency alerting, among others. The agreement between the broadcasters and American Tower will serve as a test of a developed model for the transition from ATSC 1.0 to ATSC 3.0 and the deployment of SFN sites in preparation for future national deployment of ATSC 3.0 Next Gen broadcast services.

In addition to over 40,000 U.S. tower sites and expertise in installing broadcast equipment, American Tower provides proficiency, through its ecosystem partners, in network connectivity, SFN synchronization, wireless RAN and radio frequency propagation. The result of this buildout and the associated engineering is expected to provide a deployment roadmap that delivers cost efficiencies for broadcasters and increases speed to market for new Next Gen TV services. As previously announced, Sinclair, Nexstar and Univision are parties to a memorandum of understanding regarding the establishment of a consortium that will promote spectrum aggregation, innovation and monetization and enhance their abilities to compete in the wireless data transmission sector.
