近年來資訊科技進步迅速，無線網路的應用已經是相當成熟的技術，尤其是802.11b已經是市場的主流，相關應用設備的大廠爭相投入研發與生產，形成產品價格下降迅速普及化，使用者可以大量建置無線網路的環境，走在大街小巷如捷運車站、速食店、便利商店都可以見到無線訊號的蹤跡，日前台北市在重要的經濟商圈建置無線上網的環境，只要隨身具有無線上網的設備，就可以購買申請上網的帳號，實現不在辦公室也能辦公事，即使是在捷運或是公車上都可以任意遨遊網際，提高生活的便利性，在國際上有類似的案例如美國西雅圖市區也有無線網路的環境，並且免費提供無線上網的服務，無時無刻都能與網路世界接軌。因此在充滿無線網路的環境裡，非常適合利用固定的AP進行無線定位的服務。 本論文提出以無線網路基地台訊號，建置系統資料庫，應用情境照片及語音輔助提供無線定位的服務。由於是以無線訊號來定位，假設在一個陌生的環境，系統可以發現無線基地台的訊號，經過查詢資料發現資料庫裡沒有此筆資料，即可先紀錄再互動式的通報Server由管理者核可後加入資料庫，迅速方便建立環境資料庫並且提供定位服務。系統提供使用者查詢環境內的各個據點。當使用者開啟系統接收到無線訊號經過資料比對與判斷，即可迅速將目前所在位置與照片顯示於使用者介面，並且播報語音服務。因此本系統具有反應速度快，方便、迅速定位的優點。 The information technology has developed rapidly in recent years and the use of wireless network have come to a mature technique. Especially, 802.11b have become a leading style in market. , a lot of larger manufacturers have launched into research and production with their related equipments. The users can set up the environment of wireless network widely. They can find the wireless signal at the MRT station, fast food store and convenient store. A few days ago, Taipei city install wireless networks in the main business districts. The user needs just the device of wireless network, he can purchase and apply an account to internet access. The user can work even though he is not in office. He can surf the internet easily on either MRT or bus, that make his living much more convenient. There are some similar cases in the international environment. Seattle city in USA is also one of the first community wireless network providing free wireless internet access to connect with the internet world . Therefore proper to use fixed AP station signal of wireless network to locate the location in the wireless network environment. This paper is to bring up the offering of wireless location service that is based on the signal of wireless network to build system database, and apply scenario photograph and auxiliary voice to assist the service of wireless location. As it is located with wireless signal and allowed the user to find the basic signal and get the information from the database even in a unfamiliar surrounding. When the user can find any additional information not stored on the database, he can record the information and report interactively. System administrator create an environment database to provide the location service quickly. The implemented system provides users to look up the related location of operational wireless base station in the environment. When the user starts the system to receive the wireless signal, the system estimate his location and present related photo on the display, and broadcast voice service information to user.
