ORTENGA Systems Engineering will engage with all stakeholders to capture end product requirements and decompose them to block level requirements with trade-off analysis between various architectures.

Architecture and System definition are the most important part of any radio application and must be designed and/or defined in such a way to meet system/standard requirements.  Radio definition requires both system level understanding and market trend analysis.

Partner ORTENGA to succeed in your design and product delivery to the market.

The requirements will be divided into Air and MODEM interfaces.
