Millimetre Coverage Is Blockage
The claim
Millimetre-wave coverage is set by blockage density rather than by path loss, so a dense low-rise area can outperform an open area with few reflectors.
01The mechanism
Coverage depends on the probability of a clear line of sight or a usable reflection; density sets both, in opposite directions.
02Predictions
- P1Coverage should track blockage density non-monotonically.
- P2Open areas should underperform at intermediate density.
03Refutation
Coverage tracking path loss alone would remove the blockage term.
