Two-breakpoint Model, with recommended parameters September 2004 Two-breakpoint Model, with recommended parameters PL(d )= -10log{[c/(4pdfm)]2 [1-exp(-(dt1 /d)g-2)][1-exp(-(dt2/d)2- 1]}, where: PL: pathloss, dB; d: distance between transmitter and receiver; fm: geometric mean of transmitted frequency band; g1: propagation constant after first breakpoint (3.7); g2: propagation constant after second breakpoint (10.5); c: velocity of propagation; dt1: first breakpoint distance from transmitter (5 meters); dt2: second breakpoint distance from transmitter (30 meters).
