Statistical models are helpful if the type of building can be classified:
Model Name Path Loss Equation [dB]
Retail Store PL (d) = 22 Log(3.28*d) + 20.1
Suburban Office Bldg - Open Floor Plan PL (d) = 24 Log(3.28*d) + 19.1
Suburban Office Bldg - Soft Partitions PL (d) = 28 Log(3.28*d) + 17.0
Suburban Office Bldg - Hard Partitions PL (d) = 30 Log(3.28*d) + 16.0
University PL (d) = 0.6232(d)+ 63
Motorola Cluttered PL (d) = 0.594(d) + 71
Motorola Uncluttered PL (d) = 0.3608(d) + 55
Free Space @ 894 MHz PL (d) =20 Log (3.28*d) + 21

PL: Path loss (dB)
d: Distance from Remote Radio Head to mobile user
