ATSC 3.0 SFN Network Planning and Antenna Design
The new ATSC 3.0 broadcast standard will provide new transmission capabilities. The higher signal strengths required to deliver higher data rates will be achieved via a connected single frequency network platform while continuing to utilize the existing “main stick” in the form of high power and tall towers. The addition of a SFN to the existing infrastructure provides extended, robust coverage to consumers outside the reach of the main antenna. The use of modern network planning tools provides the coverage and service predictions necessary to ensure necessary signal strengths within the entire licensed area. Current regulatory restrictions placed on licensed areas present challenges in antenna design. The techniques used to optimize the network will be discussed followed by antenna designs developed to realize the theoretical calculations.
