DiReM v1: Directional Real-deployment Multiband Radio Maps

DiReM is a radio-map dataset built from real Canadian base-station deployments. Transmitter locations, carriers, powers and sector orientations come from ISED spectrum-licence site data; the coverage is simulated with ATDI HTZ Communications using four directional antenna patterns and three transmit-power settings.

v1 is the frozen release used in the paper: 122,021 single-transmitter maps from 5,440 transmitter configurations, with inputs, targets, colour-mapped targets, metadata, the paper's train / validation / test split, and the per-configuration coverage and EMF maps.
