802.11g

The 802.11g standard offers data transfer speeds equivalent to 802.11a-up to 54 Mbps- and the wider 300-foot range of 802.11b. More importantly, 802.11g is backwardly compatible with 802.11b, so the same 802.11g WAP can service both 802.11b and 802.11g wireless nodes.

If an 802.11g network only has 802.11g devices connected, the network runs in native mode-at up to 54 Mbps-whereas when 802.11b devices connect, the network drops down to mixed mode-all communication runs only up to 11 Mbps. Table below gives you the 802.11g summary.
