Certified Direct-to-Device Satellite Engineer (CD2DSE) Certification Program by Tonex
The Certified Direct to Device Satellite Engineer CD2DSE Certification Program by Tonex prepares engineers to design and optimize satellite systems that connect directly to mass market devices without intermediate terminals. Participants explore radio frequency planning, payload and antenna design, waveform adaptations for non terrestrial networks, and robust mobility management across dynamic beams and orbits.
The program emphasizes performance engineering for real world propagation, user mobility, and power constrained devices, ensuring reliable service at scale. Cybersecurity is addressed as a core design concern, including protection of control channels, secure management of user plane traffic, and resilience against spoofing and jamming attempts. By the end of the program, participants will be able to translate requirements into validated designs that deliver secure and resilient direct to device satellite connectivity.
