 The [upstream planner](https://github.com/meshtastic/meshtastic-site-planner) runs single-tower, single-terrain simulations. LoRa Map builds on that foundation with multi-tower network planning, real-world terrain modeling, and a visitor-facing coverage portal.
 
-- **Multi-source terrain** — Go beyond flat bare-earth SRTM. Simulate against Copernicus DSM (buildings + tree canopy), ESA WorldCover LULC clutter, or a weighted aggregate that blends all three for a realistic "expected coverage" estimate.
+- **Multi-source terrain** — Go beyond flat bare-earth SRTM. Simulate against Copernicus DSM (buildings + tree canopy), ESA WorldCover LULC clutter, a weighted aggregate blend, or worst-case (max obstacle height from all models with antenna at ground level).
 - **Batch simulation matrix** — Pre-compute coverage for every combination of client hardware, antenna, and terrain model. Visitors instantly switch scenarios — no simulation wait, no admin involvement.
 - **Deadzone remediation** — Automatically find coverage gaps across your network, rank them by priority, and suggest where to place new towers with estimated coverage gain.
 - **Mesh path analysis** — Pairwise SPLAT! point-to-point between all towers. See line-of-sight status, path loss, and link quality as color-coded polylines — understand your mesh backbone at a glance.
 - **Overlap visualization** — Per-tower color-coded layers with signal-strength transparency. Multi-coverage areas render as cross-hatched patterns so you can distinguish each tower's contribution.
+- **Window mode** — Simulate a receiver behind a window. Configure FOV, glass type (single/double/triple pane), and wall material (drywall/brick/metal) for directional attenuation. A draggable cone overlay on the map lets you aim the window visually.
 - **Hardware-aware presets** — Heltec V3/V4 profiles, region-locked frequencies (CA/US/EU/AU/AS), curated antennas with automatic SWR mismatch loss calculated and deducted.
 - **Visitor portal** — Community members pick their client device and antenna from dropdowns and see personalized coverage maps. No login, no configuration, instant results.
 - **One container** — Single Podman image, one port, one volume mount. Deploys behind your existing reverse proxy in minutes.
