WLAN

WLAN (Wireless Local Area Network) is a type of computer local area network (LAN) which uses high-frequency radio signals instead of cables to communicate between devices. WLANs allow multiple devices to connect to each other quickly and securely over a relatively large area, such as a home, office, or university campus.

A key feature of WLANs is that they can use either publicly available infrastructure, such as a Wi-Fi hotspot, or a private network that requires authentication. In either case, the underlying technology remains the same. All devices connected to the network can transmit data over short-range radio waves. This makes WLANs an ideal option for organizations that want to create a wireless network in locations where it is not possible to install cables, such as temporary or outdoor setups.

As with any network, WLANs rely on hardware components such as wireless routers, antennas, and access points to communicate with devices. Each of these components plays an important role in creating secure and reliable WLANs. For example, an access point will act as a bridge between wired networks and wireless devices, providing users with access to the WLAN. Additionally, they act as a base station for sending and receiving data, allowing WLANs to connect multiple users.

In order to secure a WLAN, it is important to use reliable encryption protocols such as WPA2-Personal or WPA3. These protocols provide data encryption to prevent unauthorized users from accessing the network. They also offer other features such as authentication and data integrity to protect users’ data from hackers and malicious attacks.

WLANs are becoming increasingly common in homes, offices, and schools. With advances in technology, they are now becoming more reliable and secure, with higher speeds and better coverage. As a result, WLANs are becoming a vital part of cybersecurity efforts, providing secure wireless access to sensitive data and information.
