Automotive manufacturers are moving towards integrating all types of telematics resources into the vehicles of the future. These features bring high-speed Internet connectivity for streaming data to and from a vehicle. Samsung Electronics introduced the first telematics control unit (TCU) ready for 5G in 2019. Samsung is now talking about its 5G mm wave TCU, which will enable new functionality.
Samsung says that 5G mmWave technology reduces data transfer latency to a minimum and can cover multiple vehicles at the same time. According to Samsung, the technology would be necessary to allow fast communication between vehicles, pedestrians and infrastructure. 5G mmWave technology offers bandwidth from 100 MHz to 1 GHz, which is ten times the bandwidth offered by most wireless communication solutions today.
The wider bandwidth offered by 5G mmWave technology would allow large amounts of data to be transmitted more quickly. This would allow vehicles to provide drivers with real-time information about roads and communication between vehicles. Enabling a TCU with mmWave required a differentiated positioning and antenna design to ensure stable communications due to high penetration losses, high propagation losses and ease of signal blocking by obstacles.
To efficiently transmit, receive and use 5G mm wave signals, Samsung uses matrix antenna beam forming technology. The technology allows the antenna beams to be concentrated in a specific direction and transmitted with more power. The technology minimizes interference and increases transmission coverage. The technology also allows data to be sent and received at high speed, using a more stable connection, even if the vehicle is in motion.
Samsung’s mmWave base station has 1024 antenna elements and supports precise beam formation. Its 5G Compact Macro technology provides perfect connectivity for cars driving at up to 200 km / h. The TCU also has a heatsink structure, guaranteeing the device’s operation in extremely hot or cold temperatures. The technology will enable new safety and entertainment features in the vehicle, including autonomous driving.
