Only if you insist on carrying the signal on a single carrier.
And, more correctly, it's the bandwidth, not the frequency that
correlates with information content. The 10MHz of bandwidth
between 0 and 10MHz has the same information carrying capacity as
the 10MHz between 1GHz and 1.01GHz. The difference is in the
practicalities of modulation/demodulation and transmission.
