Eq. (5.3.2.2.2.11),
2 L" (d) = L(d0) + 2 m" log (d I d0) (for penetration area)
where the path-loss slope 211Lz is 25 dB/ dec when the receiver moves on the fifth floor (n = 2):
2 L" (d) = L(d0) + 2m2 log (d/ d0) = 54 + 25 x log (14/12)
= 54 + . 67 = 55.67 dB

The received signal at a new location (d .R = 14) is 0 dBm - 55.67 dB = -55.67 dBm.
