Not true at all. 802.11a works at various frequencies around 5 GHz, at 54 Mbps. *Consumer* access points and "WiFi routers" all used 802.11b/g radios, with some rare exceptions, such as the Linksys WRT54AG and the Buffalo AirStation WHR-HP-AG108, which had two independent radios and supported two SSIDs. I'm a happy user of the latter and had to look for quite a while before I found one for sale. I had to leave the 2.4 GHz band as it got too crowded with WiFi and crap like TV extenders. Sadly, Apple did not do dual-radio for the latest AirPort Extreme, even though the cheapest AirPort is already more expensive than that AirStation. “Earlier versions of the WiFi specification all used the 2.4GHz radio spectrum.”

Confusing but true. Try it out. Remember: Signal as stated in the chart inside Airport Utility is actually stronger when you get closer to zero. Confusing but true. Try it out.
