Definition:
The IEEE 802.11 wireless LAN standard is usually referred to as Wi-Fi-Wireless Fidelity or RLAN-Radio Local Area Network. The 802.11 standard has evolved into a number of sub-standards 802.11a/b/g/n. Each sub-standard operates in a different GHz-Giga Hertz (billions) range such as 2.4 and 5.7 GHz - the same as cordless telephones and other devices which can also cause interference with computers connected with WiFi. Each sub-standard offers a different data speed from 10-54 MBPS-Mega (millions) Bits Per Second and range of use which is generally up to 300 feet. WiFi operates in an unlicensed frequency regulated by the FCC-Federal Communications Commission (www.fcc.gov). The FCC limits transmission power to one Watt which limits the distance of use.
