What Is A SSID?

One often must deal with the word while dealing with wireless networking because it is employed for identification purposes. To be exact, the SSID or even the Service Set Identifier is the alphanumeric key that may consist of up to 32 characters (maximum) and serves to uniquely identify an invisible LAN. The idea behind the SSID identification is usually to prevent unwanted wireless users from accessing the Local Area Network setup. All devices have to be configured with similar SSID for the crooks to communicate in just a particular network. In other words, SSID is the name presented to a WLAN.

The SSID on all wireless clients normally can be set either automatically or manually. In order to the choice is yours automatically, all one needs to do is maintain the specified space blank and it ought to be create automatically. If the Service Set Identifier must however be set manually, one could must enter in the specific name into the client network settings. Automatic SSID broadcasting will not be enabled in case of certain wireless access points on account of security concerns. A network administrator would most likely work with a public SSID on the access point while broadcasting towards the wireless devices within its range.

Security

One should note that all SSIDs are case sensitive, so it will be best to be note it down somewhere in the same exact method in which it really is entered; or if the first is performing it manually, advisable to type it in mere the upper-case or even the lower-case. Naturally, the most common rules of selecting your password apply here. If the administrator disables the broadcasting of SSID in the router settings, then a SSID of the device is going to be invisible on the site survey of other devices in range. In that case, the SSID has got to be entered manually so that you can activate intercommunication. One should note that this alone is not a measure that's secure enough and so has to be used and also other forms of security measures like WEP or WPA.

Types

There are two kinds of SSIDs used now and they are the Extended Service Set Identification (ESSID) and the Basic Service Set Identification (BSSID). The BSSID is utilized in an Ad-hoc wireless network system without access points, even though the ESSID is utilized by infrastructure wireless network systems having an access point. The BSSID is really the MAC address from the Wi-Fi chipset, whilst the ESSID is only the "Network Name".
