  • 本論文的目的是利用Xilinx Virtex6 FPGA開發板(xc6vlx240t/ff1156/-2),以IEEE P802.11ah/D10.0Draft Standard中的省電模式Non-TIM Station與AP為出發點,將802.11a/g網路通訊協定的嵌入式無線收發平台進行修改,加入802.11ah中的Target Wake Time與同步部分,並期許未來能實現更多802.11ah協議之內容。論文內容主要針對現有架構下,加入需要的IP core(Intellectual Property core)外,將原架構之行為模式,也就是輪詢(Polling)方式改為中斷方式觸發傳送與接收,而實體層方面,原先由硬體控制之傳送端及接收端,增加控制電路,由軟體控制,使系統能在省電模式與Active模式下對其進行相對應的開啟與關閉,另外當Non-TIM Station省電模式時間拉長時,如何完成同步的溝通。


    Based on Non-TIM station and AP(Access Point) in IEEE P802.11ah/D1 0.0 Draft standard, the main purpose of this thesis is to use Xilinx Virtex6 FPGA board (xc6vlx240t/ff1156 / -2), we modified the 802.11a/g network communication protocol, implement the TWT(Target Wake Time) feature and synchronization. In addition, we hope can add more 802.11ah features into the systems. To fullfill those things above, the thesis mainly focus on how to add the Hardware we need, to change the original architecture’s behavior, polling to transmit and receive. We will use interrupt to replace polling. And in physical layer, PHY Tx control the antenna, we add the control circuit for software, so that software can give the command anytime we want. That makes our system can switch between Power-saving mode and Active mode, enable to disable the RF. Besides, and How to complete the synchronize with ap when Power-saving mode get longer.
