Area-to-area Lee model
radio propagation model
The Lee model for area-to-area mode is a radio propagation model used to predict a path loss over flat terrain.
The model provides a modified power law with correction factors for antenna heights and frequency.
Applicable to/under conditions
This model is suitable for using in data collected. The model predicts the behaviour of all links that has ends in specific areas.
Coverage
Originally developed for use at 900 MHz, the model includes an adjustment factor to increase the frequency range.
Mathematical formulation
The model
The Lee model is formally expressed as:
L
=
L
0
+
γ
log
d
−
10
log
F
A
{\displaystyle L\;=\;L_{0}\;+\;\gamma \log d\;-10\log {F_{A}}}
where,
L = The median path loss. Unit: decibel (dB)
L0 = The reference path loss along 1 km. Unit: decibel (dB)
γ
{\displaystyle \gamma \;}
= The slope of the path loss curve. Unit: decibels per decade
d = The distance on which the path loss is to be calculated.
FA = Adjustment factor.
“Area-to-area Lee model” enters the record as radio propagation model. Crown Archives preserves that source wording while asking what Area-to-area, model and radio can confirm, complicate or overturn.
Why this record matters
“Area-to-area Lee model” is worth following because a concise public description often conceals a longer documentary argument. Here, Area-to-area, model and radio provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 28, 2026. The linked authority identifier is Q4788679. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
