Today’s Wireless LAN Standard_IEEE 802.11g

IEEE 802.11g- describes data transfer rates as fast as IEEE 802.11a using the same technologies as, and boasts backward compatibility to, 802.11b, allowing incremental upgrades. The 802.11g standard was ratified by the IEEE in June, 2003. Wi-Fi certification has been extended to include 802.11g. More details ....

Today’s Wireless LAN Standard_IEEE 802.11a

IEEE 802.11a- specifies much faster data transfer rate than 802.11b,but lacks compatibility with IEEE 802.11b. 802.11a uses the 5 GHz UNII frequency bands. This standard was ratified by IEEE in 1999 as an amendment to the original IEEE 802.11 standard. Wi-Fi product certification has been extended to include 802.11a. More details . . .

Today’s Wireless LAN Standard_IEEE 802.11b

IEEE 802.11b-modifies 802.11 2.4GHz DSSS (Direct sequence spread spectrum) to include faster data transfer rates up to 11Mbps.This standard was the first to be widely promoted as wi-fi Alliance.802.11b was ratified by IEEE in 1999 as an amendment to the original IEEE 802.11 standard.
