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。
