什麼是SSID？(wlan中的SSID)

 原文：

Definition: An SSID is the name of a wireless local area network (WLAN). All wireless devices on a WLAN must employ the same SSID in order to communicate with each other.

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.

Also Known As: Service Set Identifier, Network Name

Examples:

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.

 

 

翻譯：

定義： SSID是一個無線局域網的名稱。同一網絡中的所有無線設備必須具有相同的SSID才能實現相互通信。

無線客戶端的SSID可以通過輸入名稱到網絡設置進行手動設置，或者自動設置爲不指定或空。網絡管理員通常使用公開的SSID，那是在接入點設置並廣播給所有在網絡範圍內的無線設備。一些新的無線接入點禁用了SSID自動廣播這個功能以提高網絡的安全性。

SSID是大小寫敏感的字符串。是一串字符或數字的字符(字母或數字)。

SSID最大長度爲32個字符。

別名： Service Set Identifier,Network Name

例子：

網絡驅動掃描那些被無線網絡廣播的SSID，然後設置到那些希望接入此網絡的客戶端。知道了SSID並不一定意味着能進入到這個忘了。這依賴於網絡管理員的設置，特別是WEP安全設置。
