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!).
-802.11b networking normally requires some [PCMCIA
] cards and a BaseStation (else you
can just use
AdHoc peer-to-peer mode)
, and provides about 11mbit
networking. Someone else flesh this one please
.
+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
.
