Understanding Ultra-Dense Cellular Networks: Multi-slope Path Loss Models and Analysis
Existing cellular network analyses, and even simulations, typically use the standard path loss model where received power decays 1/d^x over a distance d, with a pathloss exponent x. This model leads to tractable analysis of downlink cellular network performance with base stations distributed by a Poisson point process. However, it is widely known that this standard path loss model is quite idealized, and that in most scenarios the path loss exponent x is itself a function of d.
