告诉你什么是WIFI

WI-FI解释：

WIFI在掌上设备上应用越来越广泛，而智能手机就是其中一份子。

与早前应用于手机上的蓝牙技术不同，WiFi具有更大的覆盖范围和更高的传输速率，因此WiFi手机成为了目前移动通信业界的时尚潮流。

由于WiFi的频段在世界范围内是无需任何电信运营执照的免费频段，因此WLAN无线设备提供了一个世界范围内可以使用的，费用极其低廉且数据带宽极高的无线空中接口。

用户可以在WiFi覆盖区域内快速浏览网页，随时随地接听拨打电话。而其它一些基于WLAN的宽带数据应用，如流媒体、网络游戏等功能更是值得用户期待。有了WIFI功能我们打长途电话(包括国际长途哦)，浏览网页、收发电子邮件、音乐下载、数码照片传递等，再无需担心速度慢和花费高的问题。

Wi-Fi的全称是Wireless Fidelity，又叫802.11b标准。它的最大优点就是传输速度较高，可以达到11Mbps，另外它的有效距离也很长，同时与已有的各种802.11DSSS设备兼容。伴随着Intel公司提出的笔记本电脑芯片组——“迅驰”被越来越多的人认可，这一技术也逐渐成为了大家关注的话题。不过自2005年底开始，很多手机厂商，特别是以生产智能手机为主的品牌便开始将Wi-Fi引入自己的产品当中

目前已经有很多手机自带WIFI功能，但是国家信息产业部明文规定不允许带 WIFI功能的手机在国内上市，因此在国内上市的手机都不带WIFI功能。很多相同的机型在国内不能使用此功能，但在国外就可以应用!不过像586W，577W等型号手机繁体版的在国内是可以使用的WIFI功能的。

现在WIFI翻盖范围在国内越来越广泛了，高级宾馆，豪华住宅区，飞机场以及咖啡厅之类的区域都有WIFI接口。当我们去旅游，办公时，就可以在这些场所使用我们的掌上设备尽情网上冲浪了!
