Advantages of WLAN over LAN:
- Mobility: Users can move around within the range of the wireless network without losing connectivity.
- Ease of Installation: Setting up a WLAN is generally easier than running cables for a LAN.
- Aesthetics: Eliminates the need for unsightly cables.
Disadvantages of WLAN over LAN:
- Security: WLANs are more vulnerable to security breaches than LANs if not properly secured. Wireless signals can be intercepted.
- Speed: WLANs are often slower than LANs, especially with older Wi-Fi standards. Interference can also affect speed.
- Reliability: Wireless signals can be affected by walls, obstacles, and interference from other devices.
Security Considerations for WLANs: WPA2/WPA3 encryption is crucial for securing a WLAN. Strong passwords should be used, and the SSID (network name) should be hidden. MAC address filtering can also add a layer of security.
