The Voice Communication Control System (VCCS) used in the Air Traffic Control (ATC) Radar Simulator plays an essential role in supporting communication between ATC trainees and pseudo pilots during simulation-based training. However, the existing proprietary VCCS faces obsolescence issues, limited component availability, and high maintenance costs, creating challenges for long-term operational sustainability. This study proposes an Internet of Things (IoT)-based VCCS prototype as an alternative communication control solution using embedded wireless control and Android-based human-machine interfaces. The system was developed using a prototype-based approach consisting of requirements identification, conceptual architecture design, implementation, and iterative testing. Functional testing was conducted to evaluate core communication control features, followed by reliability and performance evaluation through 100 operational testing cycles. The results show that the developed prototype successfully fulfilled all primary functional requirements, including wireless connectivity, channel switching, push-to-talk control, digital volume adjustment, and voice communication. Reliability testing demonstrated an operational reliability of 96%, while cost analysis showed a cost efficiency of 91.05% compared to conventional proprietary VCCS systems. These findings indicate that the proposed IoT-based VCCS provides a practical, reliable, and economically sustainable solution for communication control modernization in aviation training environments.
