At MWC 2025, we could see related technologies being applied in various ways to automobiles, drones, and mobility. We could see various evolution directions
, such as standardized network API through open gateway, network slicing function of 5G standalone mode (SA), fast network speed according to the evolution of 5.5G, satellite communications intertwined with the evolution of 6G, and in-vehicle network and SW platform structure according to the evolution of communications.
Elmo-Nokia's Network API-based Vehicle Remote Control
Elmo, an Estonian company, collaborated with Nokia to demonstrate vehicle remote control.
Elmo prepared two demonstrations at the Nokia exhibition hall and the GSMA exhibition hall. Each will remotely control vehicles in Malaga, Spain, 900 km away, and Finland, 3,400 km away.
They also introduced the advantage of being able to develop services of other mobile carriers at once using network APIs. In addition, as 5G SA evolves in the future, network slicing technology will be applied to vehicle remote control.
The company said that it can be used to improve service through remote control of rental cars, remote control of autonomous vehicles, and even remote driving and remote delivery.

Huawei's 5.5G-based vehicle remote control
Huawei of China demonstrated a 15,000 km vehicle remote control demonstration connecting Dongguan, China. This is a demonstration of installing a 5.5G network in the Dongguan test bed and remotely controlling it.
Huawei stated that 5.5G reduces the time delay between the base station and the vehicle and is helpful for vehicle video transmission, etc.

Ericsson-KDDI-Toyota 5G SA-based network slicing demonstration
Ericsson presented a 5G vehicle application demonstration in collaboration with Japan's KDDI and Toyota. This demonstration applies network API standardization and 5G SA network slicing simultaneously.
Using standardized vehicle APIs, various data transmission-based vehicle services such as video, sensors, and voice can be developed.
In addition, network slicing can be used to guarantee data transmission speed. The demonstration showed the difference in image quality when network slicing is applied and when it is not.

MediaTek's satellite communication and 6G vehicle application vision
Taiwanese processor company MediaTek presented the importance of vehicle applications through satellite communication and distribution of edge AI and cloud AI processing through 6G.
Satellite communication can be helpful when traveling by vehicle in mountainous areas where the communication environment through ground base stations is poor.
In terms of 6G, it emphasized the advantage of reducing the burden on edge AI through fast network speed and being able to appropriately utilize cloud AI. Edge and cloud processing can be appropriately distributed depending on network conditions.

Intellectus presents vehicle AI platform based on DDS protocol As
communication speeds increase and communication quality is guaranteed, the design of a communication support platform within a vehicle also becomes necessary.
Data transmission protocols and software structures for AI processing are becoming important. Intellectus, an AI startup in Korea, exhibited int2ConneX, a platform structure that can quickly implement AI processing and vehicle data transmission based on the DDS (Data Distribution Service) protocol.
The company said that it has implemented a faster communication speed than ROS and that this can be applied to various industries such as automobiles, robots, smart factories, and defense.
Evolution of communication technology and development of vehicle application services
With the evolution of 5G and 6G, communication applications are expanding in various ways. At MWC25, we were able to see various directions of development of automobile services that apply non-terrestrial networks, network API standardization, network slicing, and fast communication speeds.
Experts at MWC25 also predicted that the development of related technologies will lead to the development of mobility market services. It is expected that the evolution of related markets will also accelerate through the discovery of new services and the creation of service profits.
