Networking... without wires!
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 peer-to-peer 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.
You may also want to read about [FresnelZone], a phenomenon which occurs with long range(?) wireless links.
