・Amateur Radio
In addition to the above radio Systems, amateur radio may be used for UA etc. In this case, you need amateur radio operator qualifications and an amateur radio station license.
Amateur radio is for self-training, communication and technology research that is exclusively for personal interest, not for financial gain. Therefore, UA using amateur radio cannot be used for business.
Amateur radio in the 5GHz band may be used, but it is allocated to secondary services in the frequency assignment plan. Therefore, it must be operated so as not to interfere with the operation of the radio stations of other primary service using the same band. In particular, the 5.8GHz band is allocated to the system which is mainly used for the ETC system of the expressway and the parking lot management etc, so we should avoid using it in the vicinity, etc. Consideration is necessary for operation.
