    IIRC, the original 802.11 was also on 900 MHz and there was even an infrared version.
    At the time 802.11b came out, 10 Mb Ethernet was still fairly common, so 11 Mb actually looked good.
    The 2.4 GHz channel numbers originated with the 1997 version and is why g and n channels 1,6 & 11 are the only non overlapping channels.
    One performance issue is when b is used in the presence of g or better as b does not understand OFDM. This means that if an OFDM device hears a b signal, it has to send a frame of b to let the b devices know how long the channel will be occupied by the faster device. For this reason, if possible, disable b on access points. Otherwise they will beacon b frames, which will slow down everything else. In fact, you should enable only the slowest you need so, for example, if all your devices support n, you don't need to enable b or g on your access point.
