IEEE 802.11 is a set of standards defined for wireless networking. 802.11 was the original standard, which came into existence in 1997. Wireless client and Base station are two different wireless stations that communicate through an interface defined by 802.11. This standard has a typical data transmission rate of 1 Mbps to 2 Mbps over the 2.4 GHz bandwidth. Data can be transmitted by any of the spread spectrum types, including Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS). The 802.11 standard uses the same Ethernet protocol as used by wired network, such as CSMA/CD, for detecting the network collisions. The security standards used in IEEE 802.11 are Wired Equivalent Privacy (WEP) and WI-FI Protected Access (WPA).
