【摘要】:正據(jù)預(yù)測,2020年的數(shù)據(jù)流量將比2010年增長1000倍。5G系統(tǒng)的研發(fā)將面向2020年移動通信的需求,包含體系架構(gòu)、無線組網(wǎng)、無線傳輸、新型天線與射頻以及新頻譜開發(fā)與利用等關(guān)鍵技術(shù)。華中科技大學(xué)光電子科學(xué)與工程學(xué)院副教授張敏明認為,5G必須具備一些基本特性:實現(xiàn)無限的頻譜效率,相對4G提高10倍;所用頻譜總帶寬比4G提高10倍;基站數(shù)量是4G的10倍;整個通信網(wǎng)絡(luò)容量提高1000
[Abstract]:It is predicted that data traffic in 2020 will increase by 1000 times than in 2010. The R & D of the system will meet the needs of mobile communications in 2020, including architecture, wireless networking, wireless transmission, New antenna, radio frequency and new spectrum development and utilization and other key technologies. Zhang Minming, an associate professor of optoelectronics science and engineering at Huazhong University of Science and Technology, believes that the 5G must have some basic characteristics: to achieve unlimited spectrum efficiency, to increase the frequency spectrum by 10 times relative to 4G, to increase the total bandwidth of the spectrum by 10 times than 4G; The number of base stations is 10 times that of 4G; the capacity of the whole communication network is increased by 1000
