&gt; That said, at 60GHz of course bandwidth is awesome.<p>The carrier frequency doesn&#x27;t tell you much about the information capacity of the channel.  The width of the frequency band used is key, which is why bandwidth is often (incorrectly) used as a synonym for data rate.<p>60GHz is the central frequency, and tells you nothing of the width of the frequency band.  The ratio of the width of the frequency band to your data rate (amongst other factors, including antenna gain and processing gain) tells you your signal-to-noise ratio.
