Samsung brings 5G mmWave technology to connected vehicles

In 2109, Samsung, along with Harman and BMW, was the first manufacturer in the world to introduce a 5G-ready TCU (Telematics Control Unit) to provide connected vehicles with an ever-increasing amount of useful data at high speed. The telematics control unit combines leading automotive technologies and connects external networks to the electronic systems in the car. The Korean company takes another step forward by unveiling the first TCU equipped with a 5G mmWave connection at CES 2021, born with the intention of facilitating the transmission of large volumes of data at even higher speeds.
Samsung claims that 5G mmWave technology minimizes data transfer latency and can cover multiple vehicles at the same time. According to the Korean manufacturer, the technology would be necessary to enable timely communication between vehicles, pedestrians and infrastructure. In fact, 5G mmWave technology offers a bandwidth from 100 MHz to 1 GHz, which is ten times wider than the bandwidth offered by most of today’s wireless communication solutions. To efficiently transmit, receive and use 5G mmWave signals, Samsung uses technology called “beamforming” for the antenna array. This allows you to concentrate the signals coming from the antennas in a specific direction and to transmit them with greater power. Beamforming technology in practice minimizes interference and increases transmission coverage. It also allows you to send and receive data at high speed using a more stable connection even if the vehicle is in motion.

Samsung predicts that 5G mmWave technology will be a solution with great potential. When the TCU Automotive mmWave 5G for vehicles is commercialized, fast and stable communications will pave the way for a whole new world of in-vehicle services. In addition, users will be able to enjoy safe and fun driving, as well as improved V2X (Vehicle to Everything) services.One of the most anticipated vehicle functions that should be closer to realization thanks to the creation of the mmWave 5G TCU is full autonomous driving. . This is thanks to the real-time data transmission without delays, which in practice allows the car to know, for example, road conditions in advance and prepare for unexpected situations. Additionally, the technology will enable use cases such as remote driving of unmanned vehicles. Driving will also be safer: the driver will be able to benefit from rapid warnings of an imminent risk, all supported by high-definition road images transmitted with an extremely short delay.
In Samsung’s intentions with the 5G mmWave TCUs the entertainment possibilities on board will also be enhanced. Among the infotainment services that will improve thanks to 5G mmWave there will be video streaming, which will be in UHD 8K, for example also for all seats on a bus or taxi. But entertainment options won’t be limited to video streaming – passengers will also be able to access content such as games, concerts and live events, and other brand new multimedia services that use technologies such as VR (virtual reality) and AR (augmented reality).
