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。

Q简语业余无线电趣谈之三：Q简语的由来和缩略语Q简语是业余无线电用的简码。

Q简语，是ITU规定、颁布的通信用简语。

Q简语最早是1912年在伦敦"Radio telegraph" 无线电通信学会发起的。

国际电讯联盟（ITU）颁布了通信用简语。

每个简语由三个字母组成并代表一个完整的意思，由于第一个字母都是Q，所以称为Q简语。

电报的传送具有数字信号的优点：抗干扰能力强，能用较小的功率，传送较远的距离，但它的缺点是占用时间较长，也就是原来用话说的语句，在翻译成摩尔斯电码传送时，花的时间比讲这些话长几至十几倍，严重影响了通信效率，字母多的单词还容易出错。

摩尔斯电码发明后不久，电报通信就被很多领域所采用。

但是，用摩尔斯电码发一些很长而又使用频繁的单词和通信用语，极为不便。

为此，人们在长期的实践中发明并使用各种缩语，就是将通信中频繁使用的单词和语句，缩为一个或几个字母。

并经过一百多年的不断演变、完善，形成了现在国际上通用的缩语。

为了处理日益增多的业务，报务员们开始自编并使用缩语，及将一些长的单词和语句缩略为少数几个甚至一个字母。

到1879年，有个名叫瓦尔特.皮.菲利甫斯的报务员，还编了一本名为《菲利甫斯码》的小册子。

系统地列出了当时一些通用的英文缩语。

当然，这种码现在用的不多了，但在此基础上经过不断的演变，完善，形成了目前国际通用的缩语。

这些缩语中，有些取其单词的字头，如：N-North，GA-Go ahead 等。

有些取读音的谐音，如：U-YOU 等，这样，无论是记忆还是使用都非常方便。

在这些缩语中，还有的是取其读音的谐音字母如 U-YOU（你）；有的是取其单词的字头，如GL-GOOD LUCK（好运）等。

除个别缩语如"73"、"88"、"55"以外，一般只用于报务通信和 QSL卡片。

在通信联络中，Q简语可以作问句，如"QRL？"（你忙吗？）；也可以作答句，如" QRL "（我很忙，请勿打扰）；也可以单独使用，如"QRT"（停止发射，关机）；也可以和其他单词一起使用，如"SRI MUST QRT NW"（对不起，现在我很忙，必须立即关机）。

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。
