The in-vehicle 5G communication module is a component that uses 5G mobile communication technology to realize data transmission and wireless network connection between the vehicle and the cellular base station. This module combines a communication chip, memory, and RF (radio frequency) circuitry, and is typically installed in a vehicle communication unit inside or on the vehicle’s roof.

The module enables real-time traffic information sharing, precise position measurement, V2X (Vehicle-to-Everything: communication between vehicles and objects) and the transfer of large amounts of data. In other words, the module ensures the key functions required for fully autonomous driving without driver involvement.

More recently, other companies have also focused on developing 5G communication modules, a key component in self-driving cars. In particular, companies compete fiercely to successfully develop modules that run on the Qualcomm® Snapdragon™ automotive 5G platform.

However, it is not easy to use 5G technology for in-vehicle communication modules because it uses high frequency bands, has higher signal loss than LTE (Long Term Evolution, 4G mobile telecommunication technology), and generates high heat due to the large amount of transmitted data.

To solve this problem, LG Innotek employs its proprietary RF circuit design technology, high-precision and high-density modular technology, and new heat-resistant materials.

The company’s 5G communication modules have low latency (1ms or less), one-tenth that of LTE modules. That’s why 5G technology is gaining traction in the self-driving car space. Because it needs to respond more instantly to changes in real-time situations.

For example, if a self-driving car traveling at 100 kilometers (62 miles) per hour detects an obstacle and activates emergency braking, the vehicle with the LTE module but with the 5G module moves 1.4m (4.5ft) and starts braking. The vehicle moves 2.8 cm (0.09 ft) and starts braking because the delay is low.

In addition, the module has higher heat resistance. It can withstand the high heat generated by the 5G network and direct sunlight on the roof without being easily deformed. The module uses a new plastic material that is less sensitive to temperature changes and is manufactured using new engineering methods during the hardening and coating process.
