3G是英文3rdGeneration的缩写
W—CDMA 即 WidebandCDMA，也称为 CDMADirectSpread，意 为宽频分码多重存取，其支持者主要是以 GSM 系统为 主的欧洲厂商，日本公司也或多或少参与其中，包括欧 美的爱立信、阿尔卡特、诺基亚、朗讯、北电，以及日 本的 NTT、富士通、夏普等厂商。这套系统能够架设 在现有的 GSM 网络上，对于系统提供商而言可以较轻 易地过渡，而 GSM 系统相当普及的亚洲对这套新技术 的接受度预料会相当高。因此 W—CDMA 具有先天的 市场优势。 CDMA2000 CDMA2000 也称为 CDMAMulti—Carrier，由美国高通 北美公司为主导提出，摩托罗拉、Lucent 和后来加入 的韩国三星都有参与，韩国现在成为该标准的主导者。 这套系统是从窄频 CDMAOne 数字标准衍生出来的， 可以从原有的 CDMAOne 结构直接升级到 3G，建设成 本低廉。但目前使用 CDMA 的地区只有日、韩和北 美，所以 CDMA2000 的支持者不如 W—CDMA 多。不 过 CDMA2000 的研发技术却是目前各标准中进度最快 的，许多 3G 手机已经率先面世。
3G 手机完全是通信业和计算机工业相融合的产物，和 此前的手机相比差别实在是太大了，因此越来越多的人 开始称呼这类新的移动通信产品为“个人通信终端”。即 使是对通信业最外行的人也可从外形上轻易地判断出一 台手机是否是“第三代”：第三代手机都有一个超大的彩 色显示屏，往往还是触摸式的。3G 手机除了能完成高 质量的日常通信外，还能进行多媒体通信。用户可以在 3G 手机的触摸显示屏上直接写字、绘图，并将其传送 给另一台手机，而所需时间可能不到一秒。当然，也可 以将这些信息传送给一台电脑，或从电脑中下载某些信 息；用户可以用 3G 手机直接上网，查看电子邮件或浏 览网页；将有不少型号的 3G 手机自带摄像头，这将使 用户可以利用手机进行电脑会议，甚至使数字相机成为 一种“多余”。 3G 通信是移 动通信市场经历了第一代模拟技术的移 动 通信业务的引入，在第二代数字移动通信市场的蓬勃发 展中被引入日程的。在当今 Internet 数据业务不断升温 中，在固定接入速率(HDSL、ADSL、VDSL)不断提升 的背景下， 3G 移 动通信系统也看到了市场的曙光，益 发为电信运营商、通信设备制造商和普通用户所关注。

8.WAP：上网所谓WAP（Wireless Application Protocol)即无线应用协议，是一项全球性的网络通信协议。WAP使移动Internet 有了一个通行的标准，其目标是将Internet的丰富信息及先进的业务引入到移动电话等无线终端之中。WAP定义可通用的平台，把目前Internet 网上HTML语言的信息转换成用WML（Wireless Markup Language)描述的信息，显示在移动电话的显示屏上。WAP只要求移动电话和WAP代理服务器的支持，而不要求现有的移动通信网络协议做任何的改动，因而可以广泛的运用于GSM、CDMA、TDMA、3G等多种网络。
9.Java：是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台的总称。用Java实现的HotJava浏览器（支持Java applet）显示了Java的魅力：跨平台、动态的Web、Internet计算。从此，Java被广泛接受并推动了Web的迅速发展，常用的浏览器现在均支持Java applet。
3.OTA：（Over－the－Air Technology）空中下载技术。是通过移动通信（GSM或CDMA）的空中接口对SIM卡数据及应用进行远程管理的技术。空中接口可以采用WAP、GPRS、CDMA1X及短消息技术。OTA技术的应用，使得移动通信不仅可以提供语音和数据服务，而且还能提供新业务下载。
用户凭借具备gpsOne定位功能的CDMA终端，注册所需的定位服务，即可享受高精度位置服 务。
