Every row is a device registration under an ACMA spectrum licence, exported from the Register of Radiocommunications Licences by a 10 km point search. Transmit and receive registrations are listed separately, so one sector antenna usually appears twice.
Spectrum licences are area based. A licensee can hold the band over this location with no registered device inside 10 km, and fixed-wireless cells reach well beyond the search radius. Empty frequency in the strip means no registered transmitter nearby, not unallocated spectrum. The band-plan ribbon shows the general Australian arrangements; confirm boundaries against the current ACMA plan before relying on them.
Coverage edges come from a link budget: the receiver described in the panel (height, antenna gain, noise figure, channel bandwidth, required signal-to-noise ratio, optional clutter margin) must see at least noise floor plus required SNR. Each tower's edge is traced along 360 bearings using the strongest registered sector in that direction, with its registered EIRP, azimuth, tilt and antenna height, the 3GPP TR 38.901 Table 7.3-1 sector pattern, and the path loss chosen: 3GPP TR 38.901 Rural Macro non line of sight (the default, the model's conservative bound), its line of sight variant for a clear open plain, or free space. Beyond the radio horizon, ITU-R P.526 smooth-earth diffraction is added, which is what ultimately bounds reach on flat ground. No terrain, buildings or vegetation are modelled; use the clutter margin for trees and crops. The 38.901 model is specified to 10 km, so edges further out are extrapolations of its slope. The cell range cap is for a known network design limit, not an RF effect. Interference at the study point is judged by I/N, the predicted level of each transmitter at the receiver compared with the receiver's noise floor: above the I/N limit (−6 dB by default, which raises the floor by 1 dB) a channel is marked interference, within 4 dB below the limit it is marginal, and further below it is clear. "Clear" means no registered transmitter is predicted to exceed the limit under the chosen model with no terrain; it is not a measurement. The range discount is an engineering margin applied everywhere at once: a discount of X% evaluates the propagation model as if every path were 1/(1 − X) times longer (earth curvature keeps the true distance), so 50% roughly halves every coverage edge and reduces the predicted levels, I/N and verdicts at the study point by the same margin. It is set to 50% by default; set it to none to see the raw model.
Wedge lengths scale with EIRP and are schematic, not coverage predictions. "Faces point" marks a transmit sector whose azimuth is within 30° of the bearing from its site to the study point.
