Summary: Hyundai Mobis is developing a 5G-based, antenna-integrated telematics control unit (MTCU) to strengthen its automotive electronics business and prepare for next-generation connected vehicle services. The solution integrates 5G communication and antenna functionality into a single built-in controller, removing the need for external antennas while enabling advanced services such as high-precision mapping, remote control for autonomous driving, and ultra-high-definition streaming. Hyundai Mobis aims to complete development in the first half of the year and accelerate global market adoption, positioning the technology as a key enabler for software-defined vehicles.
Key engineering takeaway: The 5G MTCU integrates communication hardware and antenna functions into a compact controller, supporting higher data rates, lower latency, and expanded connected services compared with current 4G systems. This architecture supports SDV requirements while improving vehicle packaging and design flexibility.
Why it matters: As vehicles transition from 4G to 5G connectivity, telematics becomes central to delivering advanced connected and automated functions. Integrated 5G solutions reduce system complexity, enable new revenue-generating services, and help OEMs differentiate vehicles in an increasingly software-driven mobility market.
On the 21st, Hyundai Mobis announced that it is developing a 5G wireless communication-based antenna-integrated telematics solution (MTCU) to strengthen its automotive electronics business in the mobility sector. MTCU (Multi-function Telematics Control Unit) is a telematics solution based on 5G communication. Telematics is a driver convenience technology that integrates information and communication technology into vehicles to provide functions such as driving route guidance, accident and theft detection, and remote control.
As the mobile communication generation transitions from 4G to 5G, market competition in the mobility sector is intensifying, particularly around the development of high-specification, multi-functional telematics products. Currently, most vehicle telematics functions worldwide operate on 4G mobile communication. Hyundai Mobis is also currently mass-producing and supplying 4G-based telematics products.
“To achieve rapid market entry in the next-generation connected car service sector, we will complete product development by the first half of this year and secure market leadership in the global market,” said Jung Soo-Kyung, Executive Vice President and Head of the Automotive Electronics Business Unit at Hyundai Mobis.
The 5G-based next-generation telematics technology being developed by Hyundai Mobis is an advanced technology that global automakers are preparing for mass production application to enhance connected car services. 5G-based telematics technology enables new services such as high-precision map services, remote control for autonomous driving, and ultra-high-definition streaming.
Currently, 4G-based communication only allows services like over-the-air (OTA) updates, car-to-home services (connecting vehicles to smart homes), and infotainment content streaming. This 5G-based control solution is also recognized as an essential technological capability required to respond to the shift towards Software-Defined Vehicles (SDVs).
In particular, the solution being developed by Hyundai Mobis eliminates the need for externally protruding antennas, integrating antenna functionality into the built-in controller. This design offers the advantage of a sleeker vehicle appearance. Hyundai Mobis plans to enhance its competitiveness in securing orders in the global market by combining its existing capabilities in developing vehicle telematics systems and mass production experience with communication technology.
To secure this market-leading technology early, Hyundai Mobis is collaborating with various mobile communication modem (data transmission/reception and signal conversion devices) specialists, including Korea’s AM.
Hyundai Mobis showcased the newly developed product at CES 2026 held in the US this month, promoting it to global customers to further expand orders.
