An adaptive power tiered cell includes inner and outer tiers. Each one of a plurality of communication channels for servicing mobile terminals operating within the cell is assigned to either the inner tier or the outer tier. When a switch of one of the channels assigned to serve mobile terminals operating in a first one of the inner and outer tiers to serving mobile terminals operating in the other one of the first and second tiers is detected, the inner at tier is re-sized such that a ratio of the area of the first tier to the area of the cell matches a ratio of the number of channels serving mobile terminals operating in the inner tier to the number of channels serving mobile terminals operating in the cell. To re-size the inner tier such that a ratio of the area of the inner tier to the area of the cell matches a ratio of the number of channels serving mobile terminals operating in the inner tier to the number of channels serving mobile terminals operating in the cell, a power level threshold value which defines an outer peripheral edge of the inner tier is adjusted.
