Android手机网络NetWorkType对应的常量值
本篇是为了方便以后使用,无需再百度
这里写图片描述
这是对应的参数类型
/**
* GPRS 2G(2.5) General Packet Radia Service 114kbps
* EDGE 2G(2.75G) Enhanced Data Rate for GSM Evolution 384kbps
* UMTS 3G WCDMA 联通3G Universal MOBILE Telecommunication System 完整的3G移动通信技术标准
* CDMA 2G 电信 Code Division Multiple Access 码分多址
* EVDO_0 3G (EVDO 全程 CDMA2000 1xEV-DO) Evolution - Data Only (Data Optimized) 153.6kps - 2.4mbps 属于3G
* EVDO_A 3G 1.8mbps - 3.1mbps 属于3G过渡，3.5G
* 1xRTT 2G CDMA2000 1xRTT (RTT - 无线电传输技术) 144kbps 2G的过渡,
* HSDPA 3.5G 高速下行分组接入 3.5G WCDMA High Speed Downlink Packet Access 14.4mbps
* HSUPA 3.5G High Speed Uplink Packet Access 高速上行链路分组接入 1.4 - 5.8 mbps
* HSPA 3G (分HSDPA,HSUPA) High Speed Packet Access
* IDEN 2G Integrated Dispatch Enhanced Networks 集成数字增强型网络 （属于2G，来自维基百科）
* EVDO_B 3G EV-DO Rev.B 14.7Mbps 下行 3.5G
* LTE 4G Long Term Evolution FDD-LTE 和 TDD-LTE , 3G过渡，升级版 LTE Advanced 才是4G
* EHRPD 3G CDMA2000向LTE 4G的中间产物 Evolved High Rate Packet Data HRPD的升级
* HSPAP 3G HSPAP 比 HSDPA 快些
