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).

Loss-per-meter Model, with recommended parameters
PL(d )= -10log{[c/(4pdfm)]2} + *d,
where:
PL: pathloss, dB;
d: distance between transmitter and receiver;
fm: geometric mean of transmitted frequency band;
: loss-per-meter parameter (0.60dB per meter);
c: velocity of propagation.
