This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
An Ethernet port on a laptop computer connected to a twisted pair cable with an 8P8C modular connector Symbol used by Apple and Google on some devices to denote an Ethernet connection. Ethernet (/ ˈ iː θ ər n ɛ t / EE-thər-net) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan ...
Ethernet is the name of the IEEE 802.3 standard for physical LAN communication [40] and Wi-Fi is a trade name for a wireless local area network (WLAN) that uses one of the IEEE 802.11 standards. [41] Ethernet cables are interconnected via switches & routers. Wi-Fi networks are built using one or more wireless antenna called access points.
Wi-Fi client devices typically connect to the access point that can provide the strongest signal within that service set. [109] Increasing the number of Wi-Fi access points for a network provides redundancy, better range, support for fast handover, and increased overall network capacity by using more channels or by defining smaller cells.
In computer networking, a wireless access point (WAP) (also just access point (AP)) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a switch or router , but in a wireless router it can also be an integral ...
Wi-Fi Direct is a Wi-Fi standard for wireless connections [1] that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than multi-hop communication like wireless ad hoc networks. The Wi-Fi Direct standard was ...
For wider area communications, wireless local area network (WLAN) is used. WLANs are often known by their commercial product name Wi-Fi. These systems are used to provide wireless access to other systems on the local network such as other computers, shared printers, and other such devices or even the internet.
