Sensitivity of cellular wireless network performance to system & propagation parameters at carrier frequencies greater than 2 GHz

This article changes the way we see models of cellular wireless networks (mobile communications systems). The existing models of radio propagation suggest that cellular network capacity should be increased by increasing/splitting the number of cells (base stations) in cellular systems. The existing approach (of cell splitting) could not explain paradox well confirmed by observation in industry that there is NO capacity increase if the cell sizes are reduced beyond several hundreds of meters. This paper explains why there is no capacity increase, what was missing in existing models and what fundamental policies change should be followed in designing future cellular networks.
