What it rests on
Every number here rests on one of six kinds of thing: a published price or datasheet, a measurement, a standard or regulation, a calculation from sourced figures, a design choice, or an assumption written down.
Standards and data
- ITU-R P.526-15 §4.5.2, delta Bullington diffraction.
- ITU-R P.452 and P.1812: how the signal weakens on its way.
- 3GPP TR 38.901 Table 7.4.1-1: shadowing widths.
- Copernicus DEM 30 m: ground heights.
- OpenStreetMap and Overture: buildings, and the masts, signs and boards along the road.
- Semtech SX1280, EBYTE E28-2G4M20S and E28-2G4M12S, Qorvo DWM3000 datasheets, and the SX1280 long range test.
- Tier prices from DigiKey, LCSC, JLCPCB, Mouser, Gainta and other sellers, 25 to 28 September 2026. Exchange rates of 4 September 2026, 48,44 TL a dollar and 1,1622 dollars a euro.
- The rows of the comparison table that are not ours come from the bibliography below. Every note under the table links to the entry it rests on.
