Brauche ich für die HF-Ausbildung zum Telematiker auch unbedingt eine Lehre in diesem Bereich?

Do I necessarily need an apprenticeship in this field for the HF training as a telematics technician?

Yes and no. Relevant basic vocational training is certainly helpful, but an apprenticeship as an EFZ telematics technician or (as the apprenticeship has been called since 2020) EFZ building IT technician is not a mandatory requirement. Please note: The "Telematics HF" or "Technician HF Telematics" course has been revised; the course content has been taught under the new course title "System Technician HF" since 2022. You can also attend the course in systems engineering at a university of applied sciences (HF) with another technical vocational qualification (EFZ), for example as an electronics technician, automation technician, electrician, IT technician or multimedia electronics technician.
