Novel expressions for the average channel capacity (ACC) of single-branch receivers operating in generalized fading channels, namely eta-mu and kappa-mu, are derived. The expressions are written in terms of the well-known Meijer's G-functions, which are easily implemented in the most popular computing softwares. In addition, it is shown that, for any given fading condition, the Nakagami-m ACC defines regions of capacity: it lowerbounds the eta-mu ACC and it upperbounds the kappa-mu ACC. In the same way, it lowerbounds the alpha-mu ACC for alpha < 2 and mu > m, and it upperbounds the alpha-mu ACC for alpha > 2 and mu < m.
