2) Predict is the more jagged line. average received signal strength for given Tx/Rx separation
where is the more jagged line.
EIRP = PtGt
d = d” then
Γ = −1
and are small
∴ PL (d) = (d / do)nwhere n : path loss exponent or
PL (dB) = PL (do) + 10 n log (d /do)
PL (d) = PL (do) + 10 n log (d / do ) + Xσ
