초록

본 논문에서는 GPS 수신기가 제공되지 않는 환경에서 무선 AP 위치 추적을 위한 방안을 마련하기 위해 AP 장비로부터 방사되는 무방향성 전파의 특성을 분석하였다. 무선 단말로부터 추적되는 AP장비나 고정된 AP 장비로 추적 가능한 무선 단말의 위치를 추적하기 위해서는 거리에 따른 수신 전력의 분포 환경을 분석하는 것이 무엇보다 중요하다. 따라서 본 논문에서는 2.4GHz 대역의 무선 전파 특성을 실내 및 실외 환경에서 거리에 따라 영향정도 및 특성을 분석하고 이를 위치 예측에 활용하였다.

In this paper, it is analyzed propagation distribution characteristics of radio wave, which is radiated on all sides from Access Point device for estimating scheme of wireless AP without GPS receiver environment. To tracking AP device is traced from wireless terminals and wireless terminal is traced from fixed AP devices, above all it is important to analysis the characteristics of receiving power in according to distance. Therefore in this paper, radio propagation characteristics of 2.4GHz wave is analyzed effect extent and quality in according to distance in doors and out doors, and utilized to location estimation.
