초록

본 연구는 metalWave 기술을 적용한 metalVox 시스템과 기존 워키토키 시스템의 함정 내 무선통신 성능을 비교하였다. 실제 함정 환경에서 테스트한 결과, metalVox는 기존 워키토키 대비 평균 15dB 높은 신호 강도를 보였으며, 3개 층 이상 떨어진 격실 간 통신에서도 안정적인 성능을 유지했다. 특히 수밀문이 닫힌 상태에서 metalVox는 -45 dBm의 평균 신호 감쇠를 기록해 워키토키의 -60 dBm보다 우수했다. Extender 사용 시 metalVox의 수신감도는 추가로 10 dB 개선되었으며, 소자장치 가동 시에도 통신 품질 저하가 미미했다. 본 연구는 metalWave 기술의 함정 내 무선통신 성능 향상 효과를 실증적으로 입증하였다.

Abstract

This study compared the in-ship wireless communication performance of the metalVox system using metalWave technology with conventional walkie-talkie systems. Tests conducted in an actual ship environment showed that metalVox achieved an average signal strength 15 dB higher than conventional walkie-talkies and maintained stable performance across compartments separated by three or more decks. Notably, with watertight doors closed, metalVox recorded an average signal attenuation of -45 dBm, outperforming the walkie-talkie’s -60 dBm. Using an extender further improved metalVox's reception sensitivity by 10 dB, and communication quality remained consistent even during equipment operation. This study empirically demonstrates the effectiveness of metalWave technology in enhancing in-ship wireless communication performance.
