    The wavelength for 2.4GHz is 4.92 inches
    The wavelength for 5 GHz is 2.3616 inches

    The higher the frequency number the shorter the wavelength. The shorter the
    wavelength the shorter the distance the signal will travel and the more
    signal loss from obstacles. This is why say am radios can reach across the
    state, where as microwaves are strictly line of site.

    The wavelength of a 2.4Ghz band transmitter is smaller then that
    of say a 5Ghz. Basically the lower you go the smaller 'footprint' your
    signal has. So the 2.4Ghz signal can pass through more things then the
    5.0Ghz signal. We proved this true when using our two wireless internet
    broadband products at the ISP I worked for. Basically, you should always
    watch where you place your AP and know how your signal will propagate.
