P-GSM900是指*基本的频率,E-GSM900是指扩展的GSM频段,R-GSM900是指铁路通信系统,ER-GSM900是指扩展的铁路通信系统。
2G通信包含GSM,GPRS,EGPRS:GPRS采用GMSK调制;EGPRS采用多时隙操作和8PSK调制技术。
3G,第三代通信系统,它能够处理图像、音乐、视频流等多种媒体形式,提供多种信息服务。测试标准EN 301 908-1, EN 301 908-2,测试频段band1,band8; 包含以下频段:
4G,是第四代通讯技术的简称, 4G系统能够以100Mbps的速度下载,上传的速度也能达到20Mbps,能够满足用户对于无线服务的要求。测试标准EN 301 908-1, EN 301 908-13 ,包含以下频段:
Band1/3/7/8/20/22/28是FDD,band 33/34/38/40/42/43是TDD
【FDD: Frequency Division Duplex(频分双工) TDD :Time Division Duplex(时分双工))】
适用范围
适用于移动通讯与数据传输设备(手机,平板,笔记本,GPRS定位器等设备)。
测试能力
此标准包含了发射要求和接收要求,信测的仪器设备、场地、环镜和人员等符合标准要求,可以完成EN 301 511, EN 301 908-1, EN 301 908-2, EN 301 908-13的检测认证,手机,平板,笔记本需要考虑SAR的测试。
样品数量/辅助设备
测试至少提供三套样品,一套完整的测试EMC,一套有RF连接线的测试RF发射与接收,一套有RF定频指令的完整样机测试辐射杂散。以及相关的辅助或周边设备,比如适配器,进入工程模式的指令等。
测试周期
一般产品的周期为7个工作日,如果产品支持2G,3G,4G周期为12个工作日。
