Abstract (in Chinese)
在現今這網路傳輸的重要性已經遠大於傳統電話傳輸的時代,網路已經成為現今大多數人生活中所不可或缺的東西,而過去傳統的傳輸-電話線在許多家庭之中已經變成了可有可無的角色,但論及費用傳統電話的通話費仍是較手機通訊的費用來的低,若是為了完全節省費用,網路通話的品質,則是遠不如傳統電話來的清晰及穩定。
本論文將依照大眾所現有的電話,電話線來做延伸結合,透過我們在本實驗所設計的通訊聯結盒,我們透過手機與無線基地台的連接,再利用802.11n所擁有的傳輸資料量大以及在連接時相當穩定的特性,使用此技術的結合我們使智慧型手機帶來了更大的便利性,智慧型行動裝置只要是在無線基地台的範圍內,我們都可以透過智慧型行動裝置接聽或是撥打家用電話,這樣的功能已經可以取代現有的一般家庭在使用的無線電話。
未來若是再配合雲端服務的發展,我們所做的通訊聯結盒,將能透過雲端的服務,即便人不在家中也能將家中的電話轉至手機,而在撥打市內電話時,也同樣可以使用雲端服務使用家中電話撥打至其他使用者的家中電,來降的使用者的電話費用,而在環保的前提下,我們將盡力使所有的使用者家中現有的通訊產品設備不做任何的淘汰,以達到節省資源不浪費並能使目標達成。
Abstract (in English)
There is become more and more important in network transmission. Internet has become a essential thing in the life. Compare with cell mobile phone users there is more and more less of traditiona telephone users in the family. For the pricing traditional phone still cheaper than mobile device. But if people want to save money mostly will choose network communications. The quality of connection traditional communication still better than network.In this reaserch we will choice 802.11n because of it`s have high speed transmission rate and very stabile quility in connect. We will base on enviromental keep all device without any eliminate to finish this research. So we will combine old and new device together and won`t waste any resource.
