Two-breakpoint Model, with recommended parameters
PL(d )= 10log{[c/(4dfm)]2 [exp((dt1 /d))][1-exp((dt2/d)2- 1]},
where:PL: pathloss, dB;d: distance between transmitter and receiver;
fm: geometric mean of transmitted frequency band;propagation constant after first breakpoint (3.7);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/(4dfm)]2} + *d,
where:PL: pathloss, dB;d: distance between transmitter and receiver;
fm: geometric mean of transmitted frequency band;loss-per-meter parameter (0.56dB per meter);c: velocity of propagation.
