通信行业术语、缩略语
4A是指：认证Authentication、账号Account、授权Authorization、审计Audit，中文名称为统一安全管理平台解决方案。
即将身份认证、授权、审计和账号（即不可否认性及数据完整性）定义为网络安全的四大组成部分，从而确立了身份认证在整个网络安全系统中的地位与作用。
AUIAUI:Attachment Unit Interface 连接单元接口AUI 端口是用来与粗同轴电缆连接的接口，它是一种"D"型15针接口，这在令牌环网或总线型网络中是一种比较常见的端口之一。
路由器可通过粗同轴电缆收发器实现与10Base-5网络的连接，但更多的是借助于外接的收发转发器（AUI-to-RJ-45），实现与10Base-T以太网络的连接。
当然也可借助于其他类型的收发转发器实现与细同轴电缆（10Base-2）或光缆（10Base-F）的连接。
这里所讲的路由器AUI接口主要是用粗同轴电缆作为传输介质的网络进行连接用的，AUI接口示意图如图所示。
BNCBNC接头，是一种用于同轴电缆的连接器，全称是Bayonet Nut Connector（刺刀螺母连接器，这个名称形象地描述了这种接头外形），又称为British Naval Connector（英国海军连接器，可能是英国海军最早使用这种接头）或Bayonet Neill Conselman（Neill Conselman刺刀，这种接头是一个名叫Neill Conselman的人发明的）。
BNC接口即常说的细同轴电缆接口。
BNC接头可没有被淘汰，因为同轴电缆是一种屏蔽电缆，有传送距离长、信号稳定的优点。
目前它还被大量用于通信系统中，如网络设备中的E1接口就是用两根BNC接头的同轴电缆来连接的，在高档的监视器、音响设备中也经常用来传送音频、视频信号。
BRASBRAS (Broadband Remote Access Server)宽带接入服务器（Broadband Remote Access Server,简称BRAS）是面向宽带网络应用的新型接入网关，它位于骨干网的边缘层，可以完成用户带宽的IP/ATM网的数据接入（目前接入手段主要基于xDSL/Cable Modem/高速以太网技术（LAN）/无线宽带数据接入(WLAN)等），实现商业楼宇及小区住户的宽带上网、基于IPSec（IP Security Protocol）的IP VPN 服务、构建企业内部Intranet、支持ISP向用户批发业务等应用。

通信英文缩写
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:系统是一项运用于的核心技术。
是IEEE继\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。
