Too many standards spoil wireless LAN soup: “Buyers have been looking for Wi-Fi logos on hardware boxes to assure compatibility. Wi-Fi5 is 802.11a, not 802.11h. But, adding to the confusion, 802.11h is likely to replace 802.11a and become Wi-Fi5” - This is a total mess, and if it does not get resolved (which presumably means going to 802.11h in the US) by the time 802.11g arrives, it will probably be irrelvant, since the latest 802.11g spec provides a/h’s bandwidth but with 802.11b compatibility.
