1、畢業(yè)設(shè)計(論文)設(shè)計(論文)題目:無線寬帶接入技術(shù)及應(yīng)用摘要72對無線寬帶網(wǎng)的研究有利于對通信行業(yè)技術(shù)進(jìn)行更加全面的了解和認(rèn)識,在以前寬帶無線接入網(wǎng)技術(shù)被廣泛且基本只應(yīng)用于“最后一公里”的接入。但是隨著更多機(jī)遇的介入,使得無線寬帶接入網(wǎng)利用其傳統(tǒng)的MMDS和LMDS技術(shù)應(yīng)用于了移動,無線,寬帶城域網(wǎng)絡(luò)中。并且許多技術(shù)研究組織對其進(jìn)行完善和修改,不斷推出新的協(xié)議,使其在物理層,接入規(guī)范,媒體接入控制層,安全保密等方面都進(jìn)行了擴(kuò)展和規(guī)范。所以在此論文中對其無線局域網(wǎng)技術(shù),WIMAX,IEEE802.16-2004和IEEE802.16-2005接口和新的無線接入技術(shù)進(jìn)行了研
2、究,在研究之中我發(fā)現(xiàn)許多技術(shù)之間的相互彌補(bǔ)或相互制約都會給無線寬帶技術(shù)帶來實際性的變化,例如想要高質(zhì)量的通信,無疑對傳輸距離,環(huán)境要求會造成損失和影響,對其的研究應(yīng)考慮多方面條件,在不同情況之下采取的不同技術(shù)和設(shè)備,所以在此研究之中采取了從結(jié)構(gòu),規(guī)格,技術(shù),應(yīng)用原理上進(jìn)行了解。通過對其多方面的研究,越發(fā)的認(rèn)為無線寬帶技術(shù)是以后一種必不可少,更加重要的技術(shù),越來越深入生活,并會從中給大家?guī)矸奖?,作為以后長遠(yuǎn)的發(fā)展,低成本,高效率,易維護(hù)將成為關(guān)鍵,所以對其的分析望大家予以指導(dǎo)和思考。關(guān)鍵詞WiMAX無線寬帶接入網(wǎng)IEEE802.16媒質(zhì)接入控制層物理層AbstractT
