Introduction
SSID stands for Service Set Identifier. A Service Set Identifier is the identification for the service set provided for the tethering of the network. A service set is a device used to provide the network to various surrounding devices; for example, a wireless local area network is a service set. Whenever an individual opens their device to connect to WiFi, the settings show several SSIDs from which a particular Service set identity can be chosen by entering the correct password. The service set identifier not only provides identification to a service set but also secures the network to prevent its privacy.
What is SSID?
SSID stands for the service set identifier, which is most commonly seen on mobile devices or laptops when we are going to connect our devices through a WiFi network. When we open the list of the available WiFi network, we see a list of names that are suggested for connections. This certain name denotation of a WiFi is known as the service set identifier. As the name suggests, a Service Set Identifier identifies the set which is providing the WiFi service. To connect to a WiFi, it is just required to select one of the SSID and then enter the correct password to connect. SSID comes with a default name around 32 characters long and includes alphabets and a numeric combination to make the connection secure.
Changing the SSID:
The SSID is the identity of the service set, which by default have an alphanumeric name. Therefore, a need to change the name comes up. Changing the SSID is a common step in which the generic username can be changed just like anyone changes its password. The changes can be done over the software configuration website of the particular modem that is in use. However, if there are any issues occurring while changing the SSID, the individual can always contact ISB technician support, which will help change the name and password if required.
Types of Service set:
A service set is termed the wireless network devices used for tethering the WiFi to connect. This service set consists of an identification character known as the Service Set Identifier (SSID). Some of the most commonly used Service Sets are:
- Infrastructure: An Infrastructure Service Set is an Access Point device that provides support for the other devices to join and use a particular network. The parameter range for the WiFi can be set with the help of configuring the access point. Basically, the WiFi set that is used in houses or business offices is a common example of an infrastructure Service Set.
- Independent: Independent Services Set can be defined as a device that does not tether WiFi itself but shares it. Basically, an independent service set works as an extender. The most common example is, extending the WiFi network by connecting it to a cellular device and sharing access to other devices.
- Mesh: Mesh service set is a large scale network sharing device that consists of self-sustained mesh networking stations. This Mesh Service Set consists of a Mesh profile to identify the WiFi network.
- Extender Service Set: An extended service set is a device that is constructed by connecting more than one access point. However, this multiple access point works as a unit to provide the network distribution throughout the homes, offices, or even the rooms with a large area. In simple words, an extended service set is the combination of more than one Infrastructure Service Set.
SSID Security:
A Service Set Identifier is quite necessary for securing the network of a Service Set. A network is not secure unless it has an SSID. There are several devices available to invade the privacy of any network; for example, a sniffer device is used to find out the SSID and convert the encryption into simpler words by using Packet switching. Therefore, securing the network is quite necessary for hackers.
Multiples SSID:
By using a multiple SSID, the individual might get the allowances of using different networks with different functions and making the efficiency of these networks quite high. It is quite easy to assign different SSID to a single Access Point. The basic reason for using the multiple SSID is to secure the network if it is being distributed between the two parties so as to prevent the sharing of information from one party to the other, i.e., prevents the invasion of privacy. One of the most common examples of multiple SSIDs is the WiFi provided in the hotels, where a single access point is provided to the guests and the employees. Here one access point has 2 SSID so as to prevent the information leak from the employees to the guests and vice versa.
Interesting Facts about SSID
- These SSIDs can be zero to 32 octets (32 bytes) long
- Under the IEEE 802.11 wireless networking standard, a “service set” refers to a collection of wireless networking devices
- To change the SSID on a network you control, you’ll have to access your router’s settings,
- Don’t create a hidden Wi-Fi network—it’s actually less secure.
- An SSID can be up to 32 characters in length.
- The wireless router or other Wi-Fi base station broadcasts its SSID, allowing nearby devices to display a list of available networks with human-readable names.
Conclusion
A service set identifier is basically the name or identity that is provided to a wireless local area network. These networks can be seen in our homes, offices, restaurants, etc. When anyone tries to connect to the network, a number of SSIDs appear on the screen to choose. SSID is not only there for identification purposes but also for securing the network from the invasion of hackers. For the easement of the Service, there are multiple SSIDs that work over a single access point that is basically used in many schools or universities, where they provide a single access point with different SSID, one for the student, another for the teachers.
