摘要

由於現代Wi-Fi網路的普遍，無論筆記型電腦、智慧型手機或平版電腦等隨身裝置，幾乎都搭配Wi-Fi功能，當通訊技術越來越成熟，Wi-Fi的普遍會成為生活中的一部份。有鑑於此，本嵌入式系統的開發是為了迎合現代和未來科技的產品走向去考量與設計。目前智慧型手機普遍都具備Wi-Fi功能，因此可透過手機的Wi-Fi去連接本系統達成遠端通訊。
本論文研究是利用微控器去控制射頻收發模組並使用組合語言編譯，設計出一套無線射頻系統，再透過此系統上設計的輸入輸出腳位與Wi-Fi系統做連接，做為無線射頻系統與Wi-Fi之間的通訊橋梁，實現運用Wi-Fi技術達成遠端通訊之目的。
Wi-Fi與無線射頻系統整合目的是以低成本達成廣泛的通訊，例如一般的家電用品要達成利用Wi-Fi網路進行無線溝通，只需安裝低成本的無線射頻系統，所以此通訊系統的開發可應用在無線感測網、物聯網、居家科技或無線的電子產品等等，應用層面非常廣泛。
本論文主要分兩大主軸，一是使用8位元微控器和nRF24L01射頻收發模組實現無線射頻傳輸系統；二是運用16位元的微控器和MRF24WB0MA之Wi-Fi模組建立Wi-Fi系統，最後將無線射頻系統與Wi-Fi系統做整合以實現遠端通訊。

Due to the prevalence of Wi-Fi networks, most of the mobile devices such as notebook, smartphone, tablet computer have the Wi-Fi capability. When the communication technology becomes more mature, the popularity of Wi-Fi also become overwhelming. In view of this, the development of the embedded system is in order to cater the products trends of modern and future to consider and design. The current smartphones general have Wi-Fi capabilities, therefore, it can through smartphone Wi-Fi to connect this system to achieve remote communication.
In this thesis, RF system has been successfully constructed, which is used microcontroller to control RF transceiver module by assembly language. Therefore, through design an I/O-pin in RF system to connect Wi-Fi system. The I/O pin works as a linkage between RF and Wi-Fi systems. Via this I/O pin, we are able to apply Wi-Fi technology to achieve remote communication function.
The purpose of integrate between Wi-Fi and wireless RF system is based on low cost to achieve extensive communication. For example, if the general household appliances want to use Wi-Fi network for wireless communication, only installation low cost wireless RF system, therefore the developed system can be used in wireless sensor network, internet of things, home technology, wireless electronic products etc., the application level is very extensive.
This thesis is divided into two main parts. The first part is the implementation of wireless RF system using 8-bit microcontroller and nRF24L01 RF transceiver. The second part is to build a Wi-Fi system by using 16-bit microcontroller and MRF24WB0MA Wi-Fi module, and to implement function of remote communication by integrating the wireless RF and Wi-Fi systems.
