what is wlan

The wireless local area network is also called the WLAN as should not be confused by Wi-Fi. Wireless networks don't require cables, but several special-purpose devices (also possessing their own radios and receiver antennas) are usually used to build them.

The device with higher intent value becomes a group owner and the second device becomes a client. A wireless LAN is a wireless computer network that links two or more devices using wireless communication to form a local area network within a limited area such as a home, school, computer laboratory, campus, or office building. An independent BSS (IBSS) is an An IBSS is a set of STAs configured in ad hoc (peer-to-peer)mode. This method is also known as Autonomous Group Owner (autonomous GO). Wireless LANs have become popular for use in the home, due to their ease of installation and use. In one approach, the user sets up a P2P group owner manually. Every BSS has an identification (ID) called the BSSID, which is the There are two types of BSS: Independent BSS (also referred to as IBSS), and infrastructure BSS.
They are also popular in Wireless LAN hardware initially cost so much that it was only used as an alternative to cabled LAN in places where cabling was difficult or impossible.

Network security remains an important issue for WLANs. A WLAN can contain as few as two devices and as many as one hundred or more. wireless LAN (WLAN or Wireless Local Area Network): A wireless LAN (or WLAN, for wireless local area network, sometimes referred to as LAWN, for local area wireless network) is one in which a mobile user can connect to a local area network ( LAN ) through a wireless (radio) connection.

The concept of a DS can be used to increase network coverage through roaming between cells. Early development included industry-specific solutions and proprietary protocols, but at the end of the 1990s these were replaced by standards, primarily the various versions of IEEE 802.11 (in products using the All components that can connect into a wireless medium in a The basic service set (BSS) is a set of all stations that can communicate with each other at PHY layer. In a Wi-Fi P2P group, the group owner operates as an access point and all other devices are clients. Wi-Fi is just a hotspot that enables one or more devices to access the internet, but the devices are not connected to each other as in the case of a local area network. Throughput in this method is halved for all clients connected wirelessly. Wireless LANs have a great deal of applications.

Stands for "Wireless Local Area Network." Oftentimes these types of public access points require no registration or password to join the network. An MIT graduate who brings years of technical experience to articles on SEO, computers, and wireless networking.

WDS also requires that every base station be configured to forward to others in the system as mentioned above. This gives users the ability to move around within the area and remain connected to the network. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection. Some wireless LANs extend an existing wired network.
In the second method, also called negotiation-based group creation, two devices compete based on the group owner intent value. There are two main methods to establish a group owner in the Wi-Fi Direct group. The WAP usually has a wired network connection and may have permanent wireless connections to other WAPs. They can be configured to different service set identifiers.

This type of WLAN is built by attaching an access point to the edge of the wired network and setting up the AP to work in bridging mode.Clients communicate with the access point through the wireless link and can reach the Ethernet network through the AP bridge connection. However, wireless networks become increasingly difficult to manage as the number of devices increases. Group owner intent value can depend on whether the wireless device performs a cross-connection between an infrastructure WLAN service and a P2P group, remaining power in the wireless device, whether the wireless device is already a group owner in another group or a received signal strength of the first wireless device. Modern implementations of WLANs range from small in-home networks to large, campus-sized ones to completely mobile networks on airplanes and trains. Users can access the Internet from WLAN hotspots in restaurants, hotels, and now with portable devices that connect to 3G or 4G networks. Through a gateway, a WLAN can also provide a connection to the wider Internet.

A wireless local area network (WLAN) provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling. Current wireless distribution systems are mostly based on Since wireless communication uses a more open medium for communication in comparison to wired LANs, the 802.11 designers also included encryption mechanisms: Most Wi-Fi networks are deployed in infrastructure mode. A bridge can be used to connect networks, typically of different types. Some networks will have multiple WAPs, using the same SSID and security arrangement.
