E392型无线上网卡采用高通公司的MDM9x00多模芯片组，同时支持TD-SCDMA/WCDMA 的3G 网络标准和LTE-TDD/FDD 的4G 网络标准。目前，利用3G网络中已经部署升级的HSPA+技术，下行峰值速率可以达到21 Mbps，上行峰值速率可以达到5.76 Mbps;部分地区采用64QAM调制技术和MIMO技术对HsPA+进行再次升级，下行峰值速率可以达到42 Mbps左右;而即将部署的4G网络，下行峰值速率可以达到i00Mbps，上行峰值速率可以达到50 Mbps。TL-WN821N 型无线网卡是基于Realtek公司的RTL8192cu芯片设计的，采用MIMO技术和空频道检测技术，支持802.11n/b/g，性能稳定且能够提供最大300 Mbps的无线传输速率，完全满足智能终端等设备的带宽需求。 3. 3G/4G路由器关键技术 3G/4G路由器是指利用WiFi的2.4GHz频段，组建一个无线局域网，并配置无线局域网的基本信息，通过Linux系统的iptables将无线局域网接人到3G/4G网络中。其关键技术具体分为3G/4G网络的接入、无线局域网的组建以及iptables的连通三个部分。 3.1 3G/4G网络的接入 该无线路由器利用E392型多模无线上网卡在嵌入式Linux系统中进行PPP拨号，分别接入到TD-SCDMA，WCDMA以及TD-LTE实验网中。其具体实现流程如图3所示。  图3 3G/4G网络接入流程图 3.1.1 多模无线上网卡驱动加载 当一个新的USB设备接入到Linux主机中，主机首先会通过控制端点读入此设备的配置，接口和端点等信息，利用控制管道完成控制型传输，然后主机再对该设备进行枚举。枚举即读取该 设备的许多重要信息，其中最重要的是读取该设备的生产商识别码(VID)以及产品识别码(PID)，将这两个识别码分别与USB内核中意存在的各个识别码进行匹配。若匹配成功，即的利用Linux系统的USB内核成功实现了 该设备的USB驱动的加载。
