通信英文缩写与中文对照
中国无线通信标准研究组（CWTS）ISP(Internet Service Provider):互联网服务提供商，即向广大用户综合提供互联网接入业务、信息业务、和增值业务的电信运营商。
ISP是经国家主管部门批准的正式运营企业，享受国家法律保护。
EV DO（EV-DO):实际上是三个单词的缩写：E volution（演进）、Data O nly。
LTE(Long T erm Ev olution):长期演进)项目是3G的演进，始于2004年3GPP的多伦多会议。
L TE并非人们普遍误解的4G技术，而是3G与4G技术之间的一个过渡，是3.9G的全球标准,它改进并增强了3G的空中接入技术，采用OFDM和MIMO作为其无线网络演进的唯一标准。
在20MH z频谱带宽下能够提供下行326Mbit/s 与上行86Mbit/s的峰值速率。
改善了小区边缘用户的性能，提高小区容量和降低系统延迟。
MIMO(M ul ti ple-I nput Mul tiple-Out-put)多如多出技术:系统是一项运用于802.11n的核心技术。
802.11n是IEEE继802.11b\a\g后全新的无线局域网技术，速度可达600Mbp s。
同时，专有MIM O技术可改进已有802.11a/b/g网络的性能。
该技术最早是由Ma rconi于1908年提出的，它利用多天线来抑制信道衰落。
根据收发两端天线数量，相对于普通的SI SO(Single-Inpu t Single-Ou tput)系统，MIMO还可以包括SIMO(Single-Inp ut Multi-ple-Ou tput)系统和MIS O(Multiple-I nput Single-Outpu t)系统。
O FDM(Orthogona l Fre quenc y Div ision M ul ti plex ing)即正交频分复用技术：实际上O FDM是MCM Multi-Ca rrierMod ulation，多载波调制的一种。
