LG Innotek has developed a 5G-V2X Cellular Module for long-distance data transmission and reception on V2V (vehicle-to-vehicle), V2P (vehicle-to-pedestrian), and V2I (vehicle-to-infrastructure) platforms. Based on a Qualcomm chip, this module provides ultra-high speed 5G data transmission which is essential for safety in autonomous driving.
This V2X (Vehicle to Everything) module consists of a communication chip, memory, RF circuits, and other supporting components. It has been designed to be mounted on the roof of the car and to receive large amounts of data required to enable autonomous driving.
According to industry estimates, a single autonomous driving vehicle produces approximately 4TB (4,000GB) of data daily, which is equivalent to downloading 8000, 90-minute movies. Given the enormity of this data, speed is crucial for processing it. For instance, in the event of unexpected accident-causing road congestion, the condition of the road should be communicated to the advanced driver assistance system (ADAS) as soon as possible to identify alternative routes. However, if data transmission is delayed, there is a risk of secondary accidents occurring due to vehicles that are unaware of the situation.
This highlights why 5G technology is gaining attention in the autonomous driving industry where an immediate response to real-time changes is essential. Consequently, experts predict that the global automobile industry will transition from using LTE (4G) to adopting cellular modules based on 5G.
LG Innotek launched the world's first 1st generation vehicle 5G cellular module in 2019. Their newly developed 2nd generation module has increased the V2X data download speed from 35Mbps to 150Mbps, which is four times higher than the previous product. Additionally, LG Innotek has improved the temperature control algorithm to minimize the signal loss caused by direct sunlight and heat. This enhancement ensures that 5G vehicle communication remains of high quality, even in temperatures as high as 194, and enables stable long-distance V2X communication up to 0.62-0.93 miles through the 5G network.
Furthermore, LG Innotek has reduced the size of its 2nd generation '5G-V2X cellular Module' by up to 20% compared to the existing product, developing it in the size of 46mm×50mm. With a size that is half that of a credit card, the module can be easily mounted inside or outside cars.
LG Innotek utilized its unique high-density, high-precision technologies to integrate 800 components for 5G communication into their 2nd generation '5G-V2X cellular Module', which is reduced in size by up to 20% compared to the existing product. This includes communication chips, memory, and other parts. This is a significant improvement over the 1st generation module which included about 480 parts. This increased number of parts shows improved quality and performance in communication.
To ensure compatibility regardless of the nation, terrain, or type of car, LG Innotek adopted the latest 5G standard (3GPP Release 16) from the 3rd Generation Partnership Project (3GPP). By improving the compatibility of the product, LG Innotek has strengthened its position to attract customers for self-driving vehicle components.
LG Innotek is engaged in a range of promotional activities in Europe, the USA, and Japan, targeting not only domestic but also global automobile companies and automotive electronics manufacturers, to commercialize the 2nd generation '5G-V2X cellular Module' by 2025.
The Vice President of the Automotive Components & Electronics Business Unit, Byaeng-kuk Yoo, expressed that “2nd generation '5G-V2X cellular Module' will become a key component in opening the period of fully autonomous driving," and added, "As the 'total solution provider on future vehicles', LG Innotek will continue to introduce innovative products on electronic components for the future cars to create differentiated value for the customer".
According to Techno System Research (TSR), a market survey agency, the worldwide deployment of 5G communication modules in cars is expected to grow from 1.7 million this year to 21.8 million by 2027.
