摘要

最近幾年2.4GHz ISM (Industrial工業、Scientific科學、Medical醫學)頻段的無線應用，如無線區域網路(Wireless Local Area Network: WLAN，亦被稱為無線傳真Wireless Fidelity：Wi-Fi)、藍牙(Bluetooth)耳機、蜂訊(Zigbee)、無線滑鼠和鍵盤、遙控器、無線電話和微波爐等，已在相互間產生可觀且廣泛的干擾。
Proprietary Protocol (專屬通訊協定，簡稱Proprietary)無線鍵盤和滑鼠是最被廣泛使用的電腦無線輸入裝置(Device)，同樣會遭受其他2.4GHz Device的干擾。我們無法改變Wi-Fi、Bluetooth和Zigbee設計者所建構的標準，但經由妥善控制Proprietary通訊協定，可減輕來自其它2.4GHz Device的干擾，特別是與IEEE 802.11n共存於同一裝置內的干擾。本論文以Cypress公司生產的2.4GHz收發器為核心，設計和比較先前和改良的Proprietary鍵盤滑鼠在抗Wi-Fi干擾的差異和改善的效果。結果顯示改良的Proprietary鍵盤滑鼠在與802.11n靠在一起時，資料遺失率大約只有5%，使用者察覺不出遲鈍現象，這有助於電腦系統搭配2.4GHz無線鍵盤滑鼠時，內部空間規劃的容易性，這是本論文最大的貢獻。未來可再精進proprietary protocol的改良，以期達到更低的資料遺失率。

In the past years, the advent of wireless applications at the 2.4GHz ISM band, e.g. wireless LAN (WLAN), Bluetooth headsets, wireless mice and keyboards, remote controls, cordless phones, microwave ovens etc, creates a significant potential for widespread interference.
Proprietary wireless mice and keyboards are the wireless input devices which are largely used in the computer industry. Both also suffer interference from other 2.4GHz devices especially Wi-Fi. The interference of the 802.11n radios coexisting in one device is more severe. In this thesis, Cypress 2.4GHz transceiver is used for design to improve Wi-Fi interference on proprietary wireless mice and keyboards. The test result shows the improved proprietary protocol well coexisting with 802.11n. The data lost rate is about 5%. Ease of configuring the computer inner space when a computer budles with 2.4GHz wireless keyboard and mouse with the bridge built-in the system. A further work can be done in the future to reach the lower data lost rate (under 5%).
