Unmask the mystery of SSIDs! This guide dives deep into wireless network names, exploring their purpose, creation, and security implications for businesses.
Key Takeaways:
- SSIDs are unique identifiers for wireless networks, allowing for multiple networks within a single location.
- They can be up to 32 characters long and are broadcasted by access points for device connection.
- Hiding SSIDs enhances security but requires manual network selection on devices.
Q: What are SSIDs and how are they used?
A: SSIDs are unique names that identify wireless networks, enabling businesses to create and manage multiple networks within a single location. They are broadcasted by access points to allow devices to find and connect to the desired network. SSIDs can be hidden for improved security, but this requires manual network selection on devices.
The abbreviation SSID stands for Service Set Identifier. This is the unique name that identifies a wireless network. It is in the packet header when a data packet is transmitted. The devices on the Wi-Fi network use this identifier for communications via the network. The name is up to 32 alphanumeric characters in length and is case sensitive. A company in one physical location may have several WLANs, and that means the business will also have wireless access points using different SSIDs.
Beaconing or SSID Broadcasting
A wireless network access point will broadcast its availability using its service set identifier. This SSID broadcast displays the Wi-Fi network name, though access to the network can be limited through security measures. The broadcasting of an SSID may also be called beaconing. Password-protected wireless networks broadcast the SSID but require the correct password for network access. SSID broadcasting can also be disabled when required.
A Service Set Identifier Is the WLAN Name
The wireless network name, the Service Set Identifier, is the reason that data is delivered to the proper destination. The SSID differs from a router name. When looking for a wireless network, users will usually see the router or station name, which should not be confused with the 32-character SSID. Every packet that moves over a WLAN has the network service set identifier. Without this identification, data delivery might not reach the correct destination when multiple wireless networks are operating in one area.
