The IEEE 802.11b standard applies to wireless LAN networks that use radio waves as the transmission medium. These networks each have a separate media access control mechanism, known as Carrier Sense Multiple Access with Collision Avoidance (CSMS/CA), that works like the CSMA/CD mechanism used by the Ethernet. The difference is that in this protocol, when a computer sends its signals, the receiving computer performs a cyclical redundancy check and sends an acknowledgement message to the sending computer if no error is detected.
The IEEE 802.11b networks run at the transmission speed of 11 Mbps with a fallback to 5.5, 2, and 1 Mbps in the 2.4 GHz bandwidth. The radio transmission medium used by these networks is called Direct Sequence Spread Spectrum (DSSS).
