A 5G communication module equipped with C-V2X functions necessary for fully autonomous driving

Developed 5G NR module for in-vehicle use and started sampling

• Alps Alpine Co., Ltd. (TOKYO: 6770, President: Nenhiro Kuriyama, Headquarters: Tokyo (hereinafter referred to as "Alps Alpine") has developed the first in-vehicle 5G NR*1 module "UMNZ1 series" as a Japanese company. The realization process of the 5G solution-oriented society in automobiles has been sampling since March.
  
  
• The 5th generation mobile communication system (5G) has the characteristics of ultra-high speed, ultra-low latency, and simultaneous connection of multiple points. It is an important technology to support the future communication society. The automotive industry also benefited greatly from the CASE (Connected, Autonomous, Shared & Services, Electric) period of great changes. The V2X system enables the car to communicate with and interconnect with various other transportation infrastructure, other vehicles, pedestrians, etc., It is said that the combination of it and 5G will promote the IoT of automobiles, such as real-time feedback of traffic conditions to navigation, real-time downloading of high-definition video and watching on the car interior display, etc., which can make this type of in-vehicle infotainment system high-end, and The state of the car can be grasped through various sensor information, and the maintenance and repair of the car can be made more efficient. In particular, one of them fills in a function that the traditional V2X system has not fully realized-speed adjustment according to signal lights or other vehicle conditions, etc., to realize the functions necessary for completely unmanned driving, which is highly anticipated by the public.
  
  
• In today's society, it is required to establish a new in-vehicle communication system applying V2X system and 5G as soon as possible. On the other hand, in order to realize this system, it is necessary to improve the traditional 4G:LTE communication function and support the multi-functional and complex processing of V2X. Therefore, there is a problem that the module becomes hot due to self-heating, and the performance of the product itself cannot be exerted. Furthermore, in response to the enlargement of the module due to the multi-functionalization, it is also required to carry out the optimized module design in consideration of the customer's substrate mounting. Because this kind of development is difficult and the resources required for development are large, the threshold for commercialization is extremely high.
  
  
• As the first Japanese company, Alps Alpine has developed the "UMNZ1 series" 5G NR module for vehicles equipped with C-V2X function. Its products comply with 3GPP*2Rel.15 specifications. By adopting a unique structure to suppress self-heating, it also considers the heat dissipation performance inside the component after mounting, so that the product performance can always be kept to the maximum. In addition, the flatness of the module is controlled through a unique design, and a product design that meets the quality of the vehicle is realized, which can be stably mounted on the client. In addition, it is also a compatible product that supports different standardized frequency bands in various regions around the world, and contributes to reducing customer development labor.
  
  
• This product has been sampled for actual use by customers since March to promote the realization of the next-generation communication solution-oriented society brought about by the V2X system and 5G.
  
  
• Alps Alpine applies Bluetooth® and Wi-Fi® technologies to automotive applications and develops various products. In this regard, it has always been a leader in the industry. The same is true for C-V2X. It signed a cooperative partnership agreement with Chinese C-V2X chip suppliers on complementary production and development, developed an All in One module*3 with a built-in V2X protocol, and participated in the interconnectivity test in China. In the C-V2X Special Zone of Wuxi City, empirical experiments continued to be carried out. Through the introduction of C-V2X, the activity centered on the world-leading China region and insisted on advancing technology development first in the industry. However, this product is aimed at global uses outside of China. It is designed to support different frequency bands in various countries, and optionally support DSDA*4, and has a design that can correspond to a wide range of uses. In the future, our company will continue to work hard to achieve safe, secure, and comfortable car travel, and continue to promote more measures in the field of networking, which is our company's advantage.
