Portal/IDB/logo_portal.png Welcome to Debian Wireless

This page is a portal to various Debian "wireless" technologies. Here are definitions for the various "wireless" technologies followed by a link to the specific Debian Wiki page for that technology.

Wi-Fi - Wireless Local Area Network (WLAN) technology standardized as IEEE 802.11 b/g/a/n. Its primary usage is to connect computers within the same house/enterprise. Note that it is often used to connect to the Internet through a DSL or cable router.
Bluetooth - Personal Area Network (PAN) technology standardized as IEEE 801.15.1. It was designed to handle short-range "low bandwith" personal communications. Typically between your mobile phone, head-set, computer, printer...
Modem/3G - Using a dedicated 3G modem card/mobile phone as a modem (connected through Bluetooth, USB..)
IrDA is a very short range (<1m) infrared optical data exchange protocol. Typical uses include exchanging files between two laptops, sending files between mobile phones and/or computers, etc. Maximum speed is 115kbps or 4mbps (see TLDP Howto,lirc)
WiMax is a Wireless MAN standardized as IEEE 802.16. It is meant to provide wireless broadband access in metropolitan areas.
Satellite Internet - Internet access provided through communications satellites, typically provided to individual users through geostationary satellites that can offer relatively high data speeds. See this Sat-HOWTO
Free Space Optics (FSO) is a telecommunication technology that uses light propagating in free space to transmit data between two points. The optical links usually use infrared laser light, although low-data-rate communication over short distances is possible using LEDs.

Proprietary

Whereas some of the newer wireless keyboards and mice (sometimes inappropriately named "cordless") tend to use Bluetooth to connect to the computer, older ones may use proprietary RF (radio-frequency) protocols. These proprietary devices always had a base or dongle which behaved like a regular PS2/USB keyboard/mouse (from the operating system point of view).
