Log-normal shadowing in mobile radio propagation models the received power fluctuation around a mean path loss value using a zero-mean Gaussian random variable with standard deviation σ, derived from measured environmental clutter effects. This concept formalizes the distinction between deterministic large-scale fading (characterized by the distance-dependent path loss exponent n) and stochastic small-scale variations within the domain of wireless communication engineering. The theory relies on statistical methods like linear regression to estimate parameters that determine critical system design metrics such as outage probability and percentage coverage area for cellular networks.
