Alps Alpine Co., Ltd. has developed the UMNZ1 Series 5G NR(*1) Module for Automotive Use, a first for a Japanese corporation. Sample shipments began in March with aims to accelerate social implementation of 5G solutions for automobiles.

Fifth generation (5G) mobile communications technology featuring ultra-fast speeds, ultra-low latency and mass connectivity has a vital role to play within communications infrastructure of future society. The automotive industry is well poised to benefit from the technology given the major transformation already underway characterized by the CASE trends of connected cars, autonomous driving, sharing and services, and electrification. Used in combination with vehicle-to-everything (V2X) systems giving vehicles the capability to communicate and interact with everything around them, such as road infrastructure, other vehicles and pedestrians, 5G is expected to contribute to greater sophistication of IVI (In Vehicle Infotainment); for example, real-time integration of traffic conditions into navigation applications and instant downloading of high-definition video to watch on a cabin display. It will also spur integration of Internet of Things (IoT) technology that will improve the efficiency of car maintenance and inspections by keeping an eye on the condition of a vehicle via a range of different sensors. One highly anticipated application is in enabling functions essential for fully autonomous driving that existing V2X systems have been unable to sufficiently support, such as adjusting speed in response to traffic signals and other vehicles on the road.

There are calls for automotive communication systems that make use of V2X systems and 5G technology to be quickly established. But first, obstacles need to be overcome. Communication functionality that is even more advanced than existing 4G LTE technology and higher functionality that comes from V2X capability demand complex processing that can lead to modules overheating, affecting their ability to perform to their full potential. Modules also tend to get bigger with increased functionality, creating a need to optimize module design for mounting to customer circuits. It is a complicated task necessitating considerable development resources and that is a major barrier to commercialization.

The newly developed UMNZ1 Series 5G NR Module for Automotive Use with C-V2X features, a first for a Japanese corporation, is compliant with 3GPP(*2) Release 15. By suppressing heat generation and employing an original structure for greater dissipation of heat inside systems after mounting, module performance is maximized at all times. Stability of the customer’s mounting process is also made possible with an original automotive-grade product design achieved by controlling the module’s flatness. In addition, the module has compatibility with the varying frequencies used by specifications worldwide, helping to reduce the development workload for customers.

Shipments of module samples began in March and soon customers will be using the modules to advance social implementation of next-generation communication solutions based on V2X systems and 5G.

Alps Alpine is a leader in application of Bluetooth® and Wi-Fi® technology to automotive product development and is at the forefront of the industry in developing technology for the C-V2X domain, too, particularly in China, which leads the world in C-V2X deployment. Teaming up with a Chinese C-V2X chip supplier under a mutually complementary production and development partnership agreement, Alps Alpine developed an All In One communication module(*3)
with a built-in V2X protocol stack and has been involved in interoperability testing in China, as well as ongoing demonstration testing within Wuxi’s designated C-V2X zone. The UMNZ1 Series is intended for global use outside China. Compatible with frequency variations among countries, the module also has optional compatibility with DSDA(*4) devices, supporting a wide range of uses. Alps Alpine will continue to harness its strengths within the connectivity domain to advance efforts toward realization of safe, reassuring and comfortable automotive mobility.
