IEEE 802.11 Standards
Nowadays there are three organizations influencing WLAN standards. They are: ITU-R : is responsible for allocation of the RF bands IEEE : specifies how RF is modulated to transfer data Wi-Fi Alliance : improves the interoperability of wireless products among vendors But the most popular type of wireless LAN today is based on the IEEE 802.11 standard, which is known informally as Wi-Fi. * 802.11a: operates in the 5.7 GHz ISM band. Maximum transmission speed is 54Mbps and approximate wireless range is 25-75 feet indoors. * 802.11b: operates in the 2.4 GHz ISM band. Maximum transmission speed is 11Mbps and approximate wireless range is 100-200 feet indoors. * 802/11g: operates in the 2.4 GHz ISM band. Maximum transmission speed is 54Mbps and approximate wireless range is 100-200 feet indoors. * 802.11n: operates in the 2.4 GHz ISM band. Maximum transmission speed is 300Mbps and approximate wireless range is 100-200 feet indoors. IS...
