LG Innotek introduces its automotive Wi-Fi 6E moduleEngineering360 News Desk | March 04, 2021
LG Innotek has introduced what it is calling the world's first automotive Wi-Fi 6E module with next-generation Wi-Fi technology. According to the company, this will allow LG Innotek to occupy a position in the vehicle communication module market, which has been previously held by Japan.
The vehicle Wi-Fi 6E module is a short-range wireless communication unit connecting the in-vehicle infotainment (IVI) system and internal smart devices and external routers to control the operation information and multimedia content. Next-generation Wi-Fi 6E with 6 GHz high-frequency band technology provides three times faster data transfer speeds than traditional Wi-Fi 5.
It is a combination of communication chips and radio frequency (RF) circuitry and is equipped with several devices in and out of the car, including audio, video and navigation (AVN), and smart antennas. Passengers can wirelessly connect movies and games from their smartphones to car displays and audio, or update software such as navigation.
In particular, with the proliferation of autonomous driving technology, cars have evolved into entertainment and relaxation spaces, and the competition for technology for key components of automotive Wi-Fi modules has become increasingly fierce. However, the interior of the car is not easy to implement the wireless communication technology Wi-Fi 6E performance due to the structure, such as high density vehicle seats.
LG Innotek has designed RF structures and antennas that minimize communication interference based on its development capabilities in vehicle communication since 2005, further enhancing data transmission and transmission performance. Previously, LG Innotek demonstrated its skills in the field of vehicle communication modules by presenting the world's first second generation V2X full module for vehicles, 5G communication module and digital key module, which increased accuracy and security in the global market.
By incorporating the Wi-Fi 6E module for vehicles, passengers can enjoy high-definition movies and AR and VR games through the car's internal display. Wi-Fi modules that are now commercially available often experience slow connections or disconnect when transmitting high-quality video. However, the data transfer rate is 1.2 Gbps, which is three times faster than traditional Wi-Fi 5 modules.
Data speed improvements can be made available in the 6 GHz band as well as traditional 2 GHz and 5 GHz frequencies. The higher the frequency, the greater the amount of data transmission. The available bandwidth is also twice as much as 2 GHz and 5 GHz. The amount of data that can be transferred at once is increased, and the length of the data travels is bound to speed up.
In addition, the automotive Wi-Fi 6E module has no buffering or stuttering even if multiple people connect at the same time. Independent RF and antenna design technologies are applied to prevent communication interference in highly dense vehicles.
It is also durable and maintains performance even with rapid temperature changes of sub-zero 40° C to image 85° C. It is not easily deformed by the heat when the car is parked outside. It was developed to withstand repeated shrinkage and expansion by widening the surface area of the circuit junction.
The Wi-Fi 6E for vehicles module is also easy to apply because it is small, slim and compatible with existing modules.
