Two-breakpoint Model

• PL(d ) -10logc/(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
• g2 propagation constant after second
  breakpoint
• c velocity of propagation
• dt1 first breakpoint distance from
  transmitter
• dt2 second breakpoint distance from
  transmitter

Loss-per-meter Model

• PL(d ) -10logc/(4pdfm)2 ?d,
• Where
• PL pathloss, dB
• d distance between transmitter and receiver
• fm geometric mean of transmitted frequency
  band
• ? loss-per-meter parameter
• c velocity of propagation
