The IEEE is working on a new WLAN standard that will support 100 Mbps: The idea behind the new standard, 802.11n, is to match the WLAN to the wired LAN in enterprises. It won't be just faster, but also more efficient, increasing throughput, or the net resulting bandwidth after network overhead is removed. (80211.a/g are 54 Mbps raw, but more like under 25 Mbps net.)
