Features

Designed for designers who actually finish the drawing.

DASCAD is built around the things you do every day on an in-building DAS or WiFi job — not the dozen things you almost never touch.

Floorplan & layout

Floorplan calibration

Import a PDF or image. Set a known dimension. Every component lands at real-world scale.

Multi-floor projects

Stack floors. Add risers between them. Cable lengths roll up automatically.

Walls with real losses

Concrete, gypsum, glass, custom — each wall material has its own RF loss. Used by the coverage prediction.

Floorplan image cleaning

Optional pass via Google Gemini that strips clutter and high-contrasts walls without changing your scale.

Components & cables

Drag-and-drop component library

Antennas, repeaters, splitters, couplers, taps, BDAs, attenuators, terminators. Pre-loaded with common manufacturer parts.

Custom parts library

Add your own components with full RF characteristics. Per-account; never overwrites the built-ins.

Cable types

LMR-400, Heliax, custom — define your own with loss-per-band curves. Connectors and tails as separate library items.

Auto cable length

Cables route in straight or orthogonal paths. Length reads off the floorplan scale.

Analysis & output

Link budget per band

6 cellular bands (700–3700 MHz) plus 2.4 / 5 / 6 GHz WiFi out of the box. Add custom bands as needed.

RF coverage prediction

Toggle the heatmap; antennas project realistic patterns through your defined walls.

One-click BoM

Excel, PPTX, and PDF outputs. Cables itemised with lengths, components grouped by manufacturer + model.

Title block + cover pages

PDF/PPTX reports include configurable cover pages and title blocks for client delivery.

Collaboration

Real-time co-editing

Multiple designers can be in the same project; changes sync over WebSocket.

Per-user libraries

Your custom parts stay yours. Shared projects can use a sender's parts without polluting the recipient's library.

Project sharing

Invite by email. View-only or edit access.

Single active session

Logging in elsewhere kicks the old session. One login, one design seat — predictable for the customer and us.
