Autonomous driving requires simultaneous communication with the surrounding environment and other vehicles, networks, road infrastructure, etc. In particular, 5G, which supports large capacity, low latency and mass connectivity, is a key technology for transmitting massive data generated by multiple sensors such as vehicle cameras and 3D high-definition map data. Consequently, car manufactures, and Telematics Unit suppliers are pushing forward with development of 5G communications products.

The 5G communication products developed are installed in cars called “connected cars.” However, the communication performance of connected vehicles needs to be tested and verified in an OTA environment as close to the real world as possible before release.
