Abstract The Study was carreid out to see whether the intensity of electromagnetic waves in each floor of a building where the sharing base station has been established is harmful to a human body, and to expect the intensity of the waves in the building. The investigate was performed on both of sharing base station either with many scatterers or without any of them. To satisfy the international standard and the domestic TTA standard, rms for each of the electromagnetic wave of every floor in the building with the station was measured from 3 location of 3 heights(1.1m,1.5m, and 1.7m). Max of the measured rsm from the each of the frequencies in the nine location was confirmed to be 48.12%(the rooftop measured value) at most, compared to the human body protection standard. The value was confirmed to satisfy the human body protection standard for each frequency. And the total value of the calculated exposure indexes for each frequency was determined to be more than 7 times lower at most, which was 0.1445, compared to the 1 standard. Since P value in both of 868MHz and 2.14GHz electromagnetic waves intensity for each base station and floor was less than 0.05, it was revealed to be meaningful, and since R-Sq(adj) value showed a value more than 50%, the regression equation was determined to fully absorb the data information. However, although the P value of both of 868MHz and 2.14GHz electromagnetic waves intensities under the integrating terms of the base station data and the floor data was showed to be less than 0,05, since R-Sq(adj) value of 868MHz electromagnetic waves intensity presented a value smaller than 50%(34.15%), it was determined that the 868MHz electromagnetic waves intensity is very much influenced by an environment with a base station. Because the electromagnetic waves intensity of 2.14GHz show R-Sq(adj) value bigger then 50%(51.8%), The regression equation model of 2.14GHz electromagnetic waves intensity was confirmed to be proper. It also turned out not to be effected by the surrounding environment near a building with the base station and the intensity of electromagnetic waves for each floor of such building was expectable by the regression equation. 본 연구는 기지국 설치 건물의 층별 전자파 강도가 인체에 유해한지, 그리고 예측 가능한지를 조사하기 위해 수행되었다. 조사는 산란체가 많은 기지국과 산란체가 적은 기지국을 선별하여 실험을 하였다. 실험은 국제 규격과 국내 TTA 표준을 모두 충족시키기 위해, 기지국이 설치된 건물의 층별로 세가지 높이(1.1m,1.5m,1.7m)를 기준으로 하여 각 높이에서 3개의 위치에서 전자파 강도의 실효값(rms)이 측정되었다. 9개의 위치에서 측정된 주파수별 실효값(rms)의 Max가 전자파 인체 보호 기준대비 최대 48.12%(옥상 측정값)로 주파수별로 인체보호 기준을 만족함을 확인하였다. 그리고 산출된 주파수 별 노출지수 합도 최대 0.1445로 기준 1대비 최대 7배 이상 낮은 수준임을 확인하였다. 기지국별, 층별 조건에서는 868MHz, 2.14GHz의 전자파 강도 모두 P>0.005로 유의하였으며, R-Sq(조정)값이 50% 이상값을 보여서 회귀 방정식이 데이터의 정보를 충분히 흡수하고 있다는 것을 확인하였다. 그러나 기지국 데이터 통합, 층별 데이터 통합 조건에서는 868MHz, 2.14GHz의 전자파 강도 모두 P>0.05 이지만, 868MHz 전자파 강도의 R-Sq(조정)값이 50%이하 값(34.15%)을 보여서, 868MHz 전자파 강도는 기지국이 설치된 환경에 많은 영향을 받는 것을 확인 할 수 있었다. 2.14GHz의 전자파 강도는 R-Sq(조정)값이 50% 이상(51.8%)를 보여서 2.14GHz의 전자파 강도의 회귀방정의 모형은 적합하였으며, 기지국이 설치된 건물의 주변 환경에 크게 영향을 받지 않고, 기지국 설치 건물의 층별 전자파 강도를 회귀 방정식으로 예측 할 수 있었다.
