IEEE 802.11 Standard
The Institute of Electrical and Electronics Engineers developed the 802.11
standard to improve compatibility of products for Wireless Local Area Networks
(WLANs). The standard has similarities with
the 802.3 standard for ethernet wired LANs. The 802.11 series are the most well-known
Wireless LAN standards.
- The first 802.11 standard was later extended
into the 802.11a, b .. g series
- 802.11a is based on OFDM and provides data rates of 6 to 54 Mbit/s in the
5GHZ band. ·
- 802.11b is based on direct sequence CDMA with user data rates of 5.5 to
11 Mbit/s. It is interoperable with an older 802.11 DSSS standard. 802.11g
further extends the bit rates.
- 802.11c sublayer functions for bridging
- 802.11d physical layer requirements
- 801.11e Quality of Service for WLANs
- 802.11f Inter Access Point Protocl
- 802.11g more than 20 Mbit/s in 2.4 GHz
- 802.22h Spectrum Managed 802.11a
- 802.11i MAC enhancements for enhanced security
- 802.11n High Throughput MIMO
