什么是SSID？(wlan中的SSID)

SSID是Service Set Identifier的缩写，
意思是：服务集标识。
SSID技术可以将一个无线局域网分为几个需要不同身份验证的子网络，每一个子网络都需要独立的身份验证，只有通过身份验证的用户才可以进入相应的子网络，防止未被授权的用户进入本网络。

The SSID on wireless clients can be set either manually, by entering the SSID into the client network settings, or automatically, by leaving the SSID unspecified or blank. A network administrator often uses a public SSID, that is set on the access point and broadcast to all wireless devices in range. Some newer wireless access points disable the automatic SSID broadcast feature in an attempt to improve network security.SSIDs are case sensitive text strings. The SSID is a sequence of alphanumeric characters (letters or numbers). SSIDs have a maximum length of 32 characters.See also - What is a Network Name?Also Known As: Service Set Identifier, Network NameExamples: Wardrivers sometimes scan for the SSIDs being broadcast by wireless LANs, then set that SSID on their client to attempt to join that WLAN. Knowing the SSID name does not necessarily mean that rogue clients will be able to join the network. It depends on how the network administrator has configured their WLAN, particularly WEP security. 翻译：定义： SSID是一个无线局域网的名称。同一网络中的所有无线设备必须具有相同的SSID才能实现相互通信。无线客户端的SSID可以通过输入名称到网络设置进行手动设置，或者自动设置为不指定或空。网络管理员通常使用公开的SSID，那是在接入点设置并广播给所有在网络范围内的无线设备。一些新的无线接入点禁用了SSID自动广播这个功能以提高网络的安全性。SSID是大小写敏感的字符串。是一串字符或数字的字符(字母或数字)。SSID最大长度为32个字符。另见：什么事网络名称？别名： Service Set Identifier,Network Name例子：网络驱动扫描那些被无线网络广播的SSID，然后设置到那些希望接入此网络的客户端。知道了SSID并不一定意味着能进入到这个忘了。
