Development of 5G Qualcomm Chip-Based Automotive Communication Modules
Improved data response time, heat resistance, and convenience


LG Innotek announced on the 16th that it has developed a 5G Qualcomm chip-based automotive communication module.

A 5G communication module for vehicles is a component that transmits and receives data between a vehicle and a base station via 5G and connects wireless networks. It is installed in the form of a module combining a communication chip, memory, RF circuit, etc., on a vehicle communication device inside the vehicle or on the roof.

By applying this module based on the Qualcomm Snapdragon Automotive 5G platform, real-time road information sharing, precise location measurement, and V2X (Vehicle-to-Everything) large-capacity data transmission are possible. This is a core function of fully autonomous driving.

If an autonomous vehicle traveling at 100 km/h detects an obstacle and needs to make an emergency stop, and the LTE module's response time is 0.05 seconds, the vehicle will only start braking after traveling about 1.4 meters.

On the other hand, the response time of LG Innotek's automotive 5G module is 0.001 seconds, which is 1/50th the level of the LTE module, allowing the vehicle to brake immediately after moving 2.8 cm.

LG Innotek has also enhanced heat resistance. It does not easily deform even under the high heat generation characteristic of 5G and direct sunlight on the vehicle roof. New plastic-based materials that are less sensitive to temperature changes were used, and a new method was applied during the curing and coating processes.

The automotive 5G communication module measures 40×50×X3.5mm and can be mounted anywhere inside or outside the vehicle. It integrates approximately 480 components, including communication chips, memory, RF circuits, and C-V2X.

It also offers high ease of application. Since it is compatible with LTE modules, the 5G module can simply be swapped out in the LTE module's location without any changes to the system design. Software optimized for the 5G module is also provided.

Because it complies with 3GPP Release 15, it can be used regardless of country, terrain, or vehicle type.

An official from LG Innotek stated, “With the development of 5G communication modules for vehicles, automakers will be able to further accelerate the commercialization of fully autonomous vehicles and connected cars,” adding, “We will continue to introduce innovative products that can provide drivers with a convenient, safe, and enjoyable driving experience.”

Meanwhile, the number of 5G communication modules installed in vehicles is expected to increase along with the rise in sales of connected cars. IHS Markit predicted that global sales of connected cars, which stood at 24 million units in 2015, would increase to 72.5 million units by 2023.
