Harman International Industries, Incorporated announced a new collaboration with Viasat Inc. to introduce in-cabin voice calling over satellite connectivity. By combining HARMAN?s Ready Connect TCU product and Viasat?s Mobile Satellite Services (MSS) satellite constellation, the collaboration unlocks a new level of reliable, resilient, ubiquitous connectivity. The SatCom-based voice calling feature facilitates essential communication where low data rate, safety-relevant connectivity is required.
The new voice-calling capability leverages HARMAN?s Ready Connect TCU, which supports 4G, 5G, and Narrowband Non-Terrestrial Network (NB-NTN) satellite connectivity using the same base solution. Viasat, acting as the Satellite Network Operator (SNO), provides access to its highly reliable satellite network and licensed global spectrum rights, ensuring a high-quality, reliable service backed by decades of operational experience. This collaboration centers on enabling baseline voice services over satellite, underpinned by Viasat?s satellite network and HARMAN?s deep heritage in delivering robust, road-ready automotive connectivity.
Alongside voice calling, the collaboration supports messaging, emergency SOS features, and low-data-rate telematics use cases through NB-NTN satcom and Ready Connect. Looking ahead, the HARMAN and Viasat partnership includes a roadmap to broadband SatCom services enabled by Viasat.
