What kind of performance can I expect with 802.11g ?
In a 802.11g-only environment, throughput is usually 4-5 times that of a 802.11b network. The maximum throughput can exceed 24 Mbps.
In a mixed 802.11g/b environment, throughput is about double that of 802.11b networks. The maximum throughput can exceed 10 Mbps.
Users can get even better erformance by using equipment with some of the 802.11g performance-enhancing technologies, such as Prism Nitro™, 125 High Speed Mode, or Broadcom's Xpress.
