Highway Networks
Keep drivers tuned to your station along hundreds of kilometers without forcing them to switch frequencies. SFN ensures seamless listening for traffic updates, music, or talk shows across major highways and transport corridors.
Overview
Low-Latency, Synchronized Coverage
Ecreso FM transmitters combine state-of-the-art SFN technologies with unmatched energy efficiency, easy setup, and robust design. Whether you’re expanding your coverage, upgrading your network, or simply looking to deliver the best broadcast experience possible, Ecreso gives you the tools to succeed. With Ecreso’s SFN capabilities, radios deliver unbeatable quality, reach more listeners, and stay ahead of the competition.
Our team of experts and partners cover the complete SFN chain from the studio to the listeners: prediction coverage, Audio/MPX IP codecs, digital FM transmitters, antennas, drive tests, content and RF synchronization, monitoring, and more. WorldCast Systems manufactures the key devices and technologies you need for top-quality SFN; this end-to-end expertise significantly simplifies your project sourcing and ensures seamless compatibility.
Benefits
Broadcasters can rely on our technical and on-the-field expertise in FM broadcast, signal test and measurement. With accurate predictive coverage, perfect control of the signals, and drive tests, WorldCast Systems' FM-SFN solution increases your base of potential listeners with boosters. This solution is also largely used for single frequency broadcasting on highways.

Our Solutions
Your FM-SFN Building Blocks
Advanced Audio/MPX over IP Transport
APT IP Codecs
A cornerstone of the APT range, the APT IP Codec is a professional solution for studio-to-transmitter links and audio contribution. Available in hardware and virtualized versions, it supports advanced technologies like SynchroStream for precise synchronization, SureStream for redundancy, and APTmpX for efficient MPX transport - delivering outstanding reliability and audio quality over IP networks.
Precise Time Synchronization
SynchroStream
WorldCast Systems' single frequency FM solution includes content transport over IP with the most stable and accurate time synchronization. Reception quality is perfectly controlled across your strategic coverage areas thanks to SynchroStream. This new technology enables you to set the location of content synchronization with an accuracy better than 50m over the overlap areas (program delays can be set by unprecedented steps of 125ns).
Secured, Low-Latency IP Transport
SureStream
Available on all APT codecs, SureStream ensures perfect audio or MPX delivery over IP by sending multiple stream copies across diverse network paths. Its intelligent redundancy engine reconstructs a flawless, low-latency stream at the receiver end - eliminating dropouts and ensuring true broadcast-grade reliability, even over imperfect networks.
High Quality MPX Compression
APTmpX
SFN can be achieved using audio or MPX/composite transport from the studio. MPX/Composite offers a higher guarantee to get the exact same signal broadcasted by each transmitter, however it requires huge bandwidth. APTmpX is the first and only non-destructive MPX/composite algorithm designed to save network bandwidth. Opting for this solution, SFN networks benefit from the best signal quality while keeping IP costs as low as possible.
Transmission with Integrated SFN Features
Ecreso FM AiO Series
The Ecreso FM AiO Series is a fully digital transmitter range combining WorldCast’s transmission expertise with powerful built-in tools. It features a software-based APT IP Decoder with SureStream and APTmpX support, along with a 5-band sound processor and RDS encoder - all in one compact solution. This integration simplifies STL deployment, reduces hardware needs, and ensures superior on-air performance.

Test & Measurement Insights
Audemat MC6 with GoldenEar
When it comes to SFN, predictions are not sufficient and the network needs to be fine-tuned based on field tests. The Audemat MC6 is the most comprehensive and versatile measurement platform for FM. We verify the good operation of your FM-SFN broadcast chain and use the Drive Test module with GoldenEar (provides a mathematical and objective quality rating of the FM signal received by listeners) to create real-world map coverage of your program.
