본 논문은 다중 대역에서 동작하는 안테나를 장착한 차세대 이동통신 기지국 시스템의 도입 가능성 분석을 위해 종래의 기지국 시스템과 케이블 손실전력을 고려한 차세대 기지국 시스템의 전력 손실 및 탄소 절감효과를 분석하였다.

차세대 기지국 시스템은 옥외에 무선처리부를 설치하고, 옥내의 기저대역처리부는 광케이블로 연결하여 종래의 기지국에서 케이블로 인해 발생하는 전력손실을 없애는 구조이다.

본 연구 결과 종래의 기지국과 비교하여 동일한 서비스 커버리지 확보가 가능하고, 케이블 전력손실이 5 dB 줄어든 차세대 기지국 시스템을 도입할 경우 CDMA 20W, WCDMA 30W, WiBro 10W 기지국에서 소모하는 전력량은 연간 155,078 MWh에서 49,038 MWh로 감소시킬 수 있으며, 탄소배출량 또한 65,878 tCO2에서 20,832 tCO2로 절감됨을 확인하였다.

따라서 차세대 기지국 시스템은 그린 IT 기술로 이용 가능할 것으로 고찰되었다.
