South Korea is a global leader in next-generation broadcasting, with major players like KBS, SBS, and MBC operating ATSC 3.0 terrestrial TV and DMB mobile networks. These technologies offer high-speed data, UHD content, and seamless mobile access. However, Single Frequency Network (SFN) architectures, which are essential for efficient spectrum use, pose a significant challenge: managing self-interference in complex terrain and dense urban areas.
In ATSC 3.0 and DMB systems, high transmitter density, reflective environments, and varied reception scenarios (fixed, portable, mobile) exacerbate the risk of SFN interference. Poor SFN design leads to signal overlap, reception issues at cell edges, and reduced network reliability.
HTZ Communications addresses this head-on. Its powerful RF simulation engine allows broadcasters to:
By integrating high-resolution terrain and clutter data, HTZ delivers accurate, real-world predictions which are critical for proactive interference mitigation and network optimisation.
ATSC 3.0 is currently deployed across South Korea and parts of the United States, while DMB remains widely used in South Korea for mobile TV and radio services. HTZ Communications ensures both platforms operate with maximum coverage and spectral efficiency.
