Wi-Fi (short for "wireless fidelity") is the popular term for a high-frequency wireless local area network (WLAN). The Wi-Fi technology is rapidly gaining acceptance in many companies as an alternative to a wired LAN. It can also be installed for a home network. Wi-Fi is specified in the 802.11b specification from the Institute of Electrical and Electronics Engineers (IEEE) and is part of a series of wireless specifications together with 802.11b, 802.11a and 802.11g

Transmission distance: Maximum length 100m
Communication speed: Max 11Mbps
Transmission mode: Direct spread spectrum mode

* IEEE802.11a
Used frequencies: 5.15GHz to 5.25GHz (4 channels)
Transmission distance: Maximum length 100m
