Wireless local area network channels using IEEE 802.11 protocols are sold mostly under the trademark WiFi. The 802.11 workgroup has documented use in five distinct frequency ranges: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz bands. Each range is divided into a multitude of channels. Countries apply their own regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges.
Client/Server and Peer-to-Peer LANs. A client/server LAN, sometimes called a two-tier LAN, is made up of powerful computers, known as servers, given the task of managing disk drives, printers and network traffic. The clients in this type of LAN are the personal computers, or workstations, that run applications. LAN's media characteristic refers to the physical connections of the devices to the network. Typically, devices connect to a LAN through coaxial cables, twisted-pair wire or fiber optic cables. A network's protocols govern the specifications for sending data on the LAN.
