3 Wireless and local area network
Using wireless devices
Wireless technology transfers data across radio waves instead of wires. Your computer may be equipped with one or more of the following wireless devices:
●Wireless local area network (WLAN)
●Bluetooth®
Computers with WLAN devices support one or more of the following IEEE industry standards:
●802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a frequency of 2.4 GHz.
●802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g WLAN device is backward compatible with 802.11b devices, so they can operate on the same network.
●802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.
NOTE: 802.11a is not compatible with 802.11b and 802.11g.
●802.11n supports data rates of up to 450 Mbps and may operate at 2.4 GHz or 5 GHz, making it backward compatible with 802.11a, b, and g.
