The important effect on capacity gain of hybrid network for different node functions

It was demonstrated that capacity gain increases with the node function capacity increasing by making some comparisons among three different node functions, for a special node function, to obtain the maximum capacity gain in a unit area, not the more base stations (BSs) are, the bigger capacity gain is, numerically the number of BSs proved to tend to a limited constant. Meanwhile, it was addressed that with the node functions capacity increasing, the average capacity gain keeps almost same regardless of different node functions, but for a definite node function, the average capacity gain asymptotically decreases with number of BSs increasing. In addition, a mismatch output result for maximum capacity versus number of base stations described in Ref. [1] was discovered, which is a bigger deviation from the actual result, and the modified result presented.
