概述
EN 301 511, EN 301 908-1, EN 301 908-2, EN 301 908-13是關于歐洲2G, 3G, 4G移動通信的電磁兼容要求和測試方法。
2G第二代手機通信技術規格,以數字語音傳輸技術為核心。測試標準EN 301 511,測試頻段GSM1800,E-GSM900; 包含以下頻段:
P-GSM900是指*基本的頻率,E-GSM900是指擴展的GSM頻段,R-GSM900是指鐵路通信系統,ER-GSM900是指擴展的鐵路通信系統。
?
2G通信包含GSM,GPRS,EGPRS:GPRS采用GMSK調制;EGPRS采用多時隙操作和8PSK調制技術。
?
3G,第三代通信系統,它能夠處理圖像、音樂、視頻流等多種媒體形式,提供多種信息服務。測試標準EN 301 908-1,?EN 301 908-2,測試頻段band1,band8; 包含以下頻段:
4G,是第四代通訊技術的簡稱, 4G系統能夠以100Mbps的速度下載,上傳的速度也能達到20Mbps,能夠滿足用戶對于無線服務的要求。測試標準EN 301 908-1,?EN 301 908-13 ,包含以下頻段:
Band1/3/7/8/20/22/28是FDD,band 33/34/38/40/42/43是TDD
【FDD:?Frequency Division Duplex(頻分雙工) ??TDD :Time Division Duplex(時分雙工))】
?
適用范圍
適用于移動通訊與數據傳輸設備(手機,平板,筆記本,GPRS定位器等設備)。
?
測試能力
此標準包含了發射要求和接收要求,信測的儀器設備、場地、環鏡和人員等符合標準要求,可以完成EN 301 511,?EN 301 908-1,?EN 301 908-2,?EN 301 908-13的檢測認證,手機,平板,筆記本需要考慮SAR的測試。
?
樣品數量/輔助設備
測試至少提供三套樣品,一套完整的測試EMC,一套有RF連接線的測試RF發射與接收,一套有RF定頻指令的完整樣機測試輻射雜散。以及相關的輔助或周邊設備,比如適配器,進入工程模式的指令等。
?
測試周期
一般產品的周期為7個工作日,如果產品支持2G,3G,4G周期為12個工作日。
