Abstract
Knife-edge diffraction has been used to estimate the effects of blocking obstacles and terrain for cellular telecommunications. Wedge diffraction is more appropriate in many cases. This paper presents simple formulas that quantify the effects of shadowing caused by rising terrain using wedge diffraction. The shadowing effect is directly related to the typical cellular-telecommunications case, where an inverse fourth-power relationship of received power with distance is characteristic
