Samsung-owned Harman has partnered with US satellite communications company Viasat to introduce in-cabin voice calls over satellite networks, extending connectivity options for automotive original equipment manufacturers (OEMs).
The collaboration introduces satellite-enabled voice calling via Samsung owned automotive tech supplier’s Ready Connect telematics control unit (TCU).
It allows drivers and passengers to make calls in locations where cellular networks are unreliable or unavailable.
The companies said the capability is intended to work alongside terrestrial mobile networks rather than replace them, offering low-data-rate connectivity for safety-related use cases when needed.
Harman Ready Connect business lead vice president Dhanaji Khade said: “Through our collaboration with Viasat, Harman Ready Connect demonstrates how its satellite-enabled architecture, which supports the 3GPP NB-NTN standard, can extend communication beyond traditional terrestrial networks.”
The solution integrates Harman’s Ready Connect TCU with Viasat’s Mobile Satellite Services (MSS) satellite constellation.
Under the arrangement, Viasat will serve as the satellite network operator (SNO), providing access to its satellite infrastructure and licensed global spectrum.
The voice-calling feature is designed to help vehicle occupants contact emergency services or roadside assistance in locations with limited mobile network access.
It also allows personal calls in unforeseen or urgent situations.
Harman stated that its Ready Connect TCU supports 4G, 5G and narrowband non-terrestrial network (NB-NTN) satellite connectivity through a single base platform.
Beyond voice services, the partnership also covers messaging, emergency SOS functions and low-data-rate telematics applications enabled by NB-NTN satellite connectivity.
These include remote vehicle operations, stolen vehicle tracking and remote diagnostics.
The companies also set out plans to expand towards broadband satellite communications using Viasat’s capabilities.
Such services could enable additional in-cabin media applications, including streaming and higher-bandwidth connectivity.
Ready Connect is built on Qualcomm’s Snapdragon Modem RF Gen 2 system and is available for integration by OEMs, according to Harman.
Viasat advanced non-terrestrial services senior vice president Sandeep Moorthy added: “Satellite connectivity has arrived for the automotive industry. Through our collaboration with Harman, vehicles can now connect directly to our satellite network.”
The company added that its Ready product suite is currently deployed with automotive manufacturers worldwide.
