近年來隨著網際網路的普遍化，網路電話應用快速地推展，Skype是目前最受歡迎網路電話軟體之ㄧ。一般使用網路電話時，皆使用傳統有線耳機及麥克風，無法任意走動，造成使用不便。本文主要係研製一2.4GHz無線Skype電話，使用2.4GHz工業、科學及醫學(Industrial Scientific and Medical，ISM)頻帶，此頻帶具有全世界各國通用之優點，其調變方式使用頻率鍵移(Frequency Shift Keying，FSK)，考慮此ISM頻道目前有無線網路及藍芽等產品使用，故使用類似藍芽協定的跳頻技術，避免其他無線電設備同頻干擾問題，並具有省電及良好的抗干擾能力。

With the booming of the internet network in recent years, the internet phone is used and promoted fast, and Skype is one of the most popular software at present. While generally using the internet phone with the traditional wired earphone and MIC wired, users are bound in front of PC or Notebook . This paper mainly focus on developing one wireless Skype phone which apply in 2.4GHz Band same as industry , science and medical science (ISM) frequency band.
Considering of this ISM channel share by lot of other applications such as wireless network , blue-tooth product and so on, here frequency hopping technology is design in for avoiding of radio equipments interfering . This application is designed with power-saving and anti-interference capability.
