Wireless Standards
Wireless technologies work as per the standards accepted
worldwide and offer different levels of security. The important aspect of
wireless standards is that, devices of different manufacturers should be able to
operate with each other and no manufacturer will use his own standard for its
device. The different wireless standards that are used for wireless networking
are IEEE 80211, Bluetooth, HomeRF and IrDA.
IEEE 802.11
802.11 is a standard created by Institute of Electrical and
Electronic Engineers (IEEE) for defining all aspects of Radio Frequency Wireless
networking. The wireless network technology uses the 802.11 standard that deals
with radio frequencies and data transmission 802.11 define the air interface
between a wireless client and a base station or between two wireless clients.
The most widely used adapted wireless network type is Wireless Fidelity (Wi-Fi). The different standard certified by Wi-Fi are 802.11, 802.11a, 802.11b, 802.11g and 802.11n.
The different IEEE 802.11 standards used for wireless networking are following
