Most commonly provided by [802.11b], which uses the 2.4GHz microwave band, designated for low-power unlicensed use by the FCC in the USA in 1985 (Reserved because 2.4GHz is the resonant frequency of water, and that's how a microwave oven works -- 2.4GHz waves break bonds in water!).
There are two primary modes an [802.11b] wlan can operate in: AdHoc (or PeerToPeer) mode, or infrastructure mode. Infrastructure mode typically offers better security than AdHoc mode. 802.11b AdHoc networking requires 2 or more computers, each with a wireless interface of some sort - [PCMCIA], [PCI], [ISA] or [USB]. Infrastructure mode also requires a BaseStation, such as an AccessPoint.
-Security is an issue that is
often ignored with WirelessNetwork~s. See WirelessNetworkSecurityNotes.
