As an inter/nationally active interest group for small and medium-sized enterprises as well as various test houses and associations in the field of radio communication, we are daily engaged in the preservation of current and future uses of the frequency bands in the sense of REC 70-03. The core task of our association is the active co-design of EN standards in cooperation with all important organizations and institutions such as ETSI and BNetzA - especially with regard to harmonization and conformity.
