通信英文缩写---精品管理资料
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。
EVDO(EV-DO):实际上是三个单词的缩写：Evolution(演进）、Data Only。
LTE(Long Term Evolution）:长期演进)项目是3G的演进，始于2004年3GPP的多伦多会议。
LTE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20MHz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（Multiple-Input Multiple-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600Mbps。
同时，专有MIMO技术可改进已有802.11a/b/g 网络的性能。
该技术最早是由Marconi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SISO（Single-Input Single—Output)系统，MIMO还可以包括SIMO（Single—Input Multi—ple-Output）系统和MISO(Multiple-Input Single—Output)系统。
OFDM(Orthogonal Frequency Division Multiplexing）即正交频分复用技术：实际上OFDM是MCM Multi—CarrierModulation，多载波调制的一种.其主要思想是:将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。
