The capacity of mobile communication systems can be increased by exploiting quiet periods of the voice. AT&T investigated this fact in the late 1960s. Still, the founded capacity gain holds only for a large number of users. In this article an analytical estimation is derived for the case that a certain number of subscribers are active. This is done by estimating the probability for a certain difference in terms of the theoretical gain.
