What are(Wireless LAN) IEEE 802.11 Networks in Computer Network?

Wireless LAN is one of the fastest-growing technologies. IEEE 802.11 refers to the set of standards that define communication for wireless LANs (wireless local area networks, or WLANs). The technology behind 802.11 is branded to consumers as Wi-Fi.

Wireless LAN can be found on college campuses, in office buildings, in hospitals, stock exchanges and in many public areas. It has become popular due to the ease of installation and location freedom with the gaining popularity of laptops.

Wi-Fi is now one of the major forms of communication for many devices, and with home automation increasing, even more, devices are using it. Home Wi-Fi is a big area of usage of technology, with most homes that use broadband connections to the Internet using WiFi access as a key means of communication.

The core of any Wi-Fi system is known as the Access Point, AP. The Wi-Fi access point is essentially the base station that communicates with the Wi-Fi enabled devices - data can then be routed onto a local area network, normally via Ethernet and typically links onto the Internet.

Advantages

There are various advantages of WLAN, which are as follows −

Fast Installation and Simplicity

Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cables through walls, floor, and ceilings.

Increased productivity for the mobile employee

The mobile user whose primary computer is a portable computer can change location and always remain connected to the network. This enables the mobile user to travel to various places, let it be meeting rooms, hallways, lobbies, cafeterias, classrooms, and so forth.

Reduced Cost

The initial investment required for wireless LAN hardware is higher than the cost of wired LAN hardware. However, the overall installation expenses and life cycle costs are significantly lower. Long-term cost benefits are greatest in dynamic environments, requiring frequent moves and changes.

Mobility and collaboration

It can stay connected while moving throughout your worksite. Access up-to-the-minute communications and all documents and apps on the network, anywhere, anytime.

Accessibility

It can provide network access across your organization, even in areas that have been challenging to reach with the wired network, so your entire team can stay in touch.

Expandability

It is used to grow your network efficiently, adding new users and locations without needing to run cables and wires.

Guest access

It can offer secure network access to guest users, including customers and business partners while keeping your network resources protected.
