WLAN equipment that could support a newer standard named 802.11g came onto the scene in 2002-2003.
Its product goal was to attempt to combine the best pros of both 802.11a and 802.11b while simultaneously attempting to do away with as many cons as possible.
802.11g also uses frequencies in an unregulated area of the wireless spectrum (2.4GHz) and likewise is much more susceptible to radio interference from other devices on the network, but it receives an extension of signal range instead.
It also supports a maximum of 54 Mbps. 802.11g network equipment also is backwards compatible with 802.11b network equipment. This means that 802.11g access points will work effectively with 802.11b wireless network adapters.
It also works well the other way around. A potential downside for the consumer is that the costs usually associated with an 802.11g network installation are higher than that of an 802.11b network installation meaning that they are less common in homes.
