LTE各种英文缩写解释

<1>RAN 无线接入网<2>RNC 无线网络控制器负责对基站进行整体管理, 包括对无线资源、本地移动用户和接入情况进行管理和控制, 并对传输情况进行优化; RNC的主要功能为无线资源管理, 网络相关功能、无线资源控制(RRC)的维护和运行, 网管系统的接口等。

RNC的主要缺点为与空中接口相关的许多功能都在RNC中, 导致资源分配和业务不能适配信道, 协议结构过于复杂, 不利于系统优化。

<3>HSDPA 高速下行链路分组接入,是一种移动通信协议,亦称为3.5G(3&frac12;G)。

该协议在WCDMA下行链路中提供分组数据业务,在一个5MHz载波上的传输速率可达8-10 Mbit/s(如采用MIMO技术,则可达20 Mbit/s)。

在具体实现中,采用了自适应调制和编码(AMC)、多输入多输出(MIMO)、混合自动重传请求(HARQ)、快速调度、快速小区选择等技术。

<4>SGSN 服务支持节点负责管理分组交换数据流量的控制和管理。

<5>GGSN 网关支持节点负责与核心网的连接。

GGSN 是本地网与外部分组交换网之间的网关, 因此也被称为GPRS路由器<6>ACGW 核心接入网关AGW 接入网关<7>RRC 无线资源控制子层<8>RLC 无线链路控制<9> PDU 协议数据单元<10>ACK 确认应答<11>FEC 前向纠错<12>ACK命令正确应答<13>OFDMA 正交频分多址<14>OFDM 正交频分复用实际上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。

正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰ICI 。

lte各种英文缩写解释

lte各种英文缩写解释

<1>RAN 无线接入网<2>RNC 无线网络控制器负责对基站进行整体管理, 包括对无线资源、本地移动用户和接入情况进行管理和控制, 并对传输情况进行优化; RNC的主要功能为无线资源管理, 网络相关功能、无线资源控制(RRC)的维护和运行, 网管系统的接口等。

RNC的主要缺点为与空中接口相关的许多功能都在RNC中, 导致资源分配和业务不能适配信道, 协议结构过于复杂, 不利于系统优化。

<3>HSDPA 高速下行链路分组接入,是一种移动通信协议,亦称为(3&frac12;G)。

该协议在WCDMA下行链路中提供分组数据业务,在一个5MHz载波上的传输速率可达8-10 Mbit/s(如采用MIMO技术,则可达20 Mbit/s)。

在具体实现中,采用了自适应调制和编码(AMC)、多输入多输出(MIMO)、混合自动重传请求(HARQ)、快速调度、快速小区选择等技术。

<4>SGSN 服务支持节点负责管理分组交换数据流量的控制和管理。

<5>GGSN 网关支持节点负责与核心网的连接。

GGSN 是本地网与外部分组交换网之间的网关, 因此也被称为GPRS路由器<6>ACGW 核心接入网关AGW 接入网关<7>RRC 无线资源控制子层<8>RLC 无线链路控制<9> PDU 协议数据单元<10>ACK 确认应答<11>FEC 前向纠错<12>ACK命令正确应答<13>OFDMA 正交频分多址<14>OFDM 正交频分复用实际上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。

正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰ICI 。

3 无线通信常用形式

3 无线通信常用形式3.1 Wi-fi3.1 ,1Wi-Fi技术简介Wi-Fi(Wireless Fidelity,无线保真技术)是IEEE 802.11的简称,是一种可支持数据,图像,语音和多媒体且输出速率高达54Mb/s的短程无线传输技术,在几百米的范围内可让互联网接入者接收到无线电信号。

外语缩写WI-FI,关于"Wi-Fi”这个缩写词的发音,根据英文标准韦伯斯特词典的读音注释,标准发音为/ˈwaɪ.faɪ/因为Wi-Fi这个单词是两个单词组成的,所以书写形式最好为WI-FI。

由澳洲政府的研究机构CSIRO在90年代发明并于1996年在美国成功申请了无线网技术专利,是IEEE定义的无线网链接技术。

Wi-Fi是一种可以将个人电脑、手持设备(如pad、手机)等终端以无线方式互相连接的技术,事实上它是一个高频无线电信号。

可以简单的理解为无线上网,几乎所有智能手机、平板电脑和笔记本电脑都支持无线保真上网,是当今使用最广的一种无线网络传输技术。

Wi-Fi的形态图描述了一个Wi-Fi能量场的大小,以及信号的传播方式Wi-Fi是一种以波的形式传输的能量场。

信号波具有一定高度,彼此间存在距离,以一定的速度传输。

Wi-Fi信号波之间的距离介于无线电波短和微波之间,使得Wi-Fi具有特殊的传输频带,可以免受其他信号干扰。

Wi-Fi波波长约3至5英寸。

波峰代表1,波谷代表0。

用0和1两个数码来表示的二进制数据生成网站、邮件和其他网络内容上的字母,数字和代码。

典型的Wi-Fi波从波源向外传输时振幅逐渐减弱,所以图中右边部分信号波大于左边部分。

可以想象出波源在图片右侧。

此图片显示出在一个频带上传输的理想化Wi-Fi数据,该频带分为不同的子信道,呈现出红色、黄色、绿色和其他不同颜色。

Wi-Fi波以编码了数据的快速脉冲或者波的形式传输。

图中定格的脉冲显示彼此间距离约为6英寸。

Wi-Fi路由器可以同时以多个频率发送数据。

无线通信技术相关术语

无线通信技术相关术语

无线技术相关术语解释GSM/2GGSM(全球移动通信:GlobalSystemForMobileCommunication)是1992年欧洲规范化委员会统一推出的规范,它采用数字通信技术、统一的网络规范,使通信质量得以保证,并可以开发出更多的新业务供用户使用。

GSM移动通信网的传输速度为9.6K/s。

目前,全球的GSM移动用户已经超过5亿,覆盖了1/12的人口,GSM技术在世界数字移动电话领域所占的比例已经超过70%。

由于GSM 相对模拟移动通讯技术是第二代移动通信技术,所以简称2G。

目前,我国拥有8000万以上的GSM用户,成为世界第一大运营网络。

GPRSGPRS(通用无线分组业务:GeneralPacketRadioService)是一种基于GSM系统的无线分组交换技术,提供端到端的、广域的无线IP连接。

简单的说,GPRS是一项高速数据处理的技术,其方法是以“分组”的形式传送数据。

网络容量只在所需时分配,不要时就释放,这种发送方式称为统计复用。

目前,GPRS移动通信网的传输速度可达115k/s。

GPRS是在GSM基础上发展起来的技术,是介于第二代数字通信和第三代分组型移动业务之间的一种技术,所以通常称为2.5G。

WAPWAP(无线应用通讯协议:WirelessApplicationProtocol)是移动通信与互联网结合的第一阶段性产物。

这项技术让使用者可以用手机之类的无线装置上网,透过小型屏幕遨游在各个网站之间。

而这些网站也必须以WML(无线标记语言)编写,相当于国际互联网上的HTML(超文件标记语言)。

打个比喻,GPRS和GSM都是马路,而WAP是在马路上的汽车。

中国移动开通GPRS之后,WAP就行驶在GSM和GPRS两条马路上,而行驶在GPRS的马路上可以提高数据传输速度。

因此,现有WAP上的内容一样可以通过GPRS进行浏览和应用。

WAP是2.5G的协议。

2.5G其它2.5G技术。

2.5G移动通信技术是从2G迈向3G的衔接性技术,目前出现的 2.5G衔接技术还包括:HSCSD、EDGE、EPOC 等。

通信英文缩写

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-InputSingle-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。

通信英文缩写

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。
