The Ministry of Science and ICT collects opinions from the Ministry of Land, Infrastructure and Transport… 20 MHz for LTE-V2X, 30 MHz for Wave The government has deployed a frequency of 70 MHz for the next-generation intelligent transportation system (C-ITS) pilot project. The Ministry of Science and ICT (Minister Hyesuk Lim) announced on the 16th that it had finalized the frequency allocation plan for the C-ITS pilot project after collecting opinions from the Ministry of Land, Infrastructure and Transport (Minister Noh Hyung-wook). This is expected to speed up the construction of the C-ITS infrastructure that the Ministry of Land, Infrastructure and Transport is pursuing. C-ITS is a road communication infrastructure that enables the sharing and response of traffic risk information in advance through vehicle-to-vehicle and vehicle-to-road communication. In August of last year, the Ministry of Science and ICT and the Ministry of Land, Infrastructure and Transport decided to promote a pilot project for the Wi-Fi-based WAVE and mobile communication-based LTE-V2X communication methods. In order to conduct a pilot project for both technologies, a new frequency allocation plan was needed, and the Ministry of Science and ICT comprehensively reviewed frequency usage efficiency, international trends, safety use, and protection of existing users and confirmed it. The Ministry of Science and ICT has confirmed the frequency allocation plan for the C-ITS pilot project.

In addition, the remaining 20 MHz width will be set as a guard band, but it will be used for next-generation C-ITS technology development such as 5G-V2X. The guard band is to place channels apart to prevent interference and interference between WAVE and LTE-V2X heterogeneous technologies. In the future, it plans to use it for the development of next-generation technologies such as 5G-V2X. Choi Woo-hyeok, director of radio wave policy bureau, said that the basis for pilot projects for both C-ITS technologies has been laid as the frequency allocation plan is finalized. To this end, he said that he would continue to cooperate between ministries.
