ORTENGA works with client and stakeholders to identify goals and deliverables of the project.

The project can range from technical feasibility, competitor analysis, radio/wireless architecture and system, HW, FW, SW, Algorithm design and developments.

ORTENGA is comprised of SME for radar and wireless communication systems and provides engineering skills where there is a gap in the client project roadmap, for duration of the project.

Typical HW could have antenna elements or array, transceiver, and baseband module with FPGA.
