摘要

無線通訊技術日新月異已給人類生活上革命性的突破，行動通訊除了縮短人與人之間的距離，帶給一般民眾許多的便利，但隨著無線通訊的普及，這項新興技術可能對人類造成的負面影響，亦逐漸受到一般民眾的注意，尤其是在人手一機的通訊手機上的輻射電磁波，因靠於耳邊經常性的使用，其所發射出的電磁波能量，可能會被人體吸收，產生細胞病變。
本論文採用高頻電磁場分析儀為檢測儀器（EMR-200），對行動電話的接收與撥打進行電場的量測，並了解距離和電場強度之間的關係，與是否符合國內的限制標準內。本論文以中原大學校園為主要的量測環境，了解室內、室外、地面與樓頂在有限的頻段範圍內的差異與障礙物對電磁波的影響。

The rapid growth of wireless telecommunication techniques gives people’s life a revolutionary breakthrough. Mobile telecommunication not only connects people but also brings convenience for populace. However, with the popularity of wireless communication, the up-to-date technique has negative influence on human beings, and its side effects are gradually addressed. One of the most devastating effects is its radioactive electromagnetic wave emitting from cellular phones. Because of the frequent use of almost adhering to ears, its electromagnetic emissions are possibly absorbed by human bodies, and cause cell deformation accordingly.
High frequency EMR-200 is employed in this thesis. Transmission and reception of cellular phones are measured so as to understand the interrelation between distance and magnitude, and further to gauge whether or not its figures are within domestic restricted standard. The campus of Chung Yuan Christian University is the experimental environment in an attempt to find out the discrepancy within the finite frequency boundary which is noted indoors, outdoors, on the ground, and on top of buildings respectively. The influence of blockages towards electromagnetic waves are concened, too.
