Current mobile networks are not able to support this diversity efficiently but are designed for peak-provisioning and typical Internet traffic.The use of very dense, low-power, small-cell networks with very high spatial reuse is a promising way to allow for handling future data rate demands [1], [2]. Small cells exploit two fundamental effects. First, the distance between the RAP and terminals is reduced, which increases the line-of-sight probability and reduces the path loss. Second, the spectrum is used more efficiently because each RAP uses the same spectrum.
