SSID (Service Set IDentifier) can be described as wireless local area network (WLAN). All the wireless devices on a WLAN should use the same SSID so they can facilitate interaction with each other. SSID is also labeled: Network Name Service, Set Identifier and ESSID (Extended Service Set IDentifier).

There are usually two ways of setting SSID on wireless clients; the manual method and the automatic method. While using the manual method the SSID is placed within the settins for the client's network. With the automatic method the SSID is allowed to remain automatic or blank. A public SSID that is set on the access point is normally used by network administrator. This approach creates a chance for the transmitting of data and support to all systems within range. In a bid to improve network security a number of the more recent wireless access points will turn off the automated SSID broadcast feature.
SSIDs are are case sensittive text strings. It is actually one particular string of characters and numbers adhering to a maximum length of 32 characters.

How a SSID PerformsAn SSID identifies a 802.11(Wi-Fi) network. The SSID is actually a secret key designed by the wireless network administrator. Users are required to know the SSID in order to connect with an 802.11 wireless network. The SSID however could possibly be found through network scanning. The SSID is displayed by default as a part of the header for each individual packet forwarded by way of the WLAN.

Radio signals are perpetually broadcast by SSID access points. In cases where client machines are empowered, these radio signals will be collected by the systems. The client connection to the access point is facilitated because of the automatic or manual configuration. Although an SSID is typically 32 items long, it is presented for the benefit of the user using human readable ASCII format. Several access points may may utilize the same SSID if they are connected to the same wireless network. Because several wireless access points allow broadcasting of quite a few SSIDs encourages the making of Virtual Access Points. These Virtual Access Points seperate a solitary physical access point into quite a few logical access points. Each one of these created logical access points feature a special set of security and network settings.

SSID Safety Challenges
The network administrators tend to discover a severe management issue is caused by the fact thatthe SSID really is a secret key and not a public key. It means that each individual individual who is using the network must configure the SSID into their system. As a result the network administrator needs to alter the SSID of the network to be able to refuse an individual right of entry. Consequently the SSID on each and every network node must be reconfigured. On the plus side some 802.11 NICs encourage the configuration of several SSIDs in a single action.

Default SSID's
Access point vendors for 802.11 typically allow for the use of ??~any??T .This permits an 802.11 NIC to connect to any network. Wireless equipment from Buffalo Technologies, D-Link, Cisco, Proxim, Intermec and Enterasays tend to facilitate this.The SSID is communicated in plain text format on each occasion that the client engages in a connection with wireless network.
