手机专业术语
一、与运营商相关的术语1、GSMGSM是全球移动通信系统（GLOBAL SYSTEM OF MOBILE）的缩写，它是由欧洲电信标准化协会（ETST）制定的一种数字移动电话系统标准。
手机铃声免费下载/2、CDMACDMA是Code Division Multiple Access的缩写，即码分多址。
它是根据美国标准（IS－95）设计的频率在900－1800MHZ范围的数字移动电话系统。
CDMA系统抗干扰能力强、系统容量大、接通率高、噪声小、发射功率小的新型数字网，能实现移动电话的各种智能业务。
3、SIM卡SIM卡是Subscriber Identity Modle（用户识别模块）的简写，它是存储用户的签约信息的，PIN是SIM卡的密码。
4、PINPIN是Personal Identity Number的缩写，意为个人用户识别码，是为防止手机被盗用而设定的密码，有4位数组成，初始值是1234，用户可以按照手机说明书操作更改。
如果连续三次输入错误的PIN码，SIM卡将被锁住。
PIN码有PIN1和PIN2码两种，PIN1就是SIM卡的个人识别密码。
PIN2是设定手机计费时使用的。
如果输入三次错误，需要用PUK2码解锁。
PIN2、PUK2这两种密码与网络计费及SIM卡内部资料的修改有关，所以不会公开，而且即便PIN2密码锁死，也不会影响手机的正常使用。
因此，PIN2码和PUK2码不必去刻意理会。
搞笑铃声/gaoxiao/5、PUK解锁码（PUK）是SIM卡的解锁码。
从技术上将，当用户的SIM卡被锁住后，用户应输入SIM卡解锁码（PUK码），输入正确，SIM卡的锁才能打开。
如果输入10次错误的PUK码，SIM卡将自动报废。
如果用户不慎把SIM卡锁住了，有两种方法解决：1）立即关掉手机电源，不再对手机做任何操作，然后带手机与SIM卡以及购机凭证到运营商的营业厅去请技术人员解锁。
2）致电运营商的服务热线，在经过简单的用户资料核对后，即可获取PUK码，解开手机锁。

通信专业词汇
通信专业词汇通信专业是一个与信息传输和交流有关的学科领域，涉及到许多专有的词汇和术语。
了解和掌握这些词汇对于学习和研究通信专业至关重要。
本文将介绍一些通信专业常用的词汇，帮助读者更好地理解和应用这些概念。
一、基础通信概念1. 信号（Signal）信号是指携带信息的物理量或波形。
在通信中，信号负责传递和表示信息。
常见的信号类型包括模拟信号和数字信号。
2. 噪声（Noise）噪声是指在信号传输过程中产生的干扰信号。
在通信系统中，噪声是不可避免的，它会降低信号的质量和可靠性。
3. 带宽（Bandwidth）带宽是指系统传输信号的频率范围。
它表示信号能够传输的最高频率。
带宽越大，传输的数据量越大。
4. 调制（Modulation）调制是指利用调制信号将信息传输到载波上的过程。
常见的调制方式包括调幅、调频和调相。
5. 解调（Demodulation）解调是指从调制信号中恢复出原始信息的过程。
二、通信网络1. 信道（Channel）信道是指信号传输的媒介，可以是电缆、光纤或无线传输介质等。
不同的信道具有不同的传输特性和带宽。
2. 网络拓扑（Network Topology）网络拓扑是指多个节点（设备）之间的连接方式。
常见的网络拓扑包括星型、环形、总线型和网状型等。
3. 路由（Routing）路由是指在网络中选择最佳路径将数据从源节点传输到目标节点的过程。
路由选择的准则包括距离、带宽和拥塞情况等。
4. 协议（Protocol）协议是指在通信中规定数据交换标准和规则的规范。
不同的通信协议适用于不同的通信场景和需求。
5. 互联网（Internet）互联网是全球范围内的公共网络，通过TCP/IP协议进行数据传输和交换。
它由各种物理网络和路由器组成。
三、无线通信1. 扩频（Spread Spectrum）扩频是一种通过使用更宽的带宽来传输数据的技术。
它提高了信号的抗噪声能力和抗干扰能力。
2. 多路复用（Multiplexing）多路复用是指在同一信道上同时传输多个信号的技术。
