辦公室無線網路2.4GHz電磁場量測與曝露安全探討

Abstract

近年來各機關行業使用網路來協助資料傳遞、銷售、採購已相當普及，隨著科技進步，擁有行動性、不佔空間等優勢的無線網路已廣為人們所使用。

無線網路係利用電磁波來傳遞訊號，而長時間曝露於電磁波下可能會造成人體的影響，雖然目前還不能明確的肯定電磁波對人體的影響程度，但由許多國家都已訂出標準，且WHO亦積極地進行相關研究，由此可見其重要性。

本論文採用電磁場強度計為檢測儀器，對無線網路的接收與發送進行電磁場強度的量測，並了解距離和電磁場強度之間的關係，與是否符合國內的限制標準。本論文以某大樓辦公室為主要的量測環境，了解室內在有限的頻段範圍內的差異電磁場強度與資料上傳與下載對電磁波強度的影響，並進一步提出建議與改善方法。

In recent years, the Internet has been widely used in organizations to assist information transfer, marketing, and product purchase. Technology advancing, wireless network has become popular with its mobile feature.

Wireless network utilizes electromagnetic waves to transmit data, a process that may harm the human body under long-term exposure to them; yet still without substantial evidence to confirm this argument. Many countries, however, have already set up standards to regulate the use of electromagnetic waves. World Health Organization (WHO) also actively investigates into this issue, indicating its urgency.

This study has utilized electromagnetic field strength meter to measure the intensity of electromagnetic waves emitted by wireless network, and to understand the relationship between the intensity and distance—examining whether or not the score is under the standard.The office was the main subject of this study. This study aims to probe into the effects of electromagnetic waves on the human body inside an office, while one is uploading or downloading data through wireless network.
