📡 How to Design a DAS Network

🏢 Step 1: Open DAS Design

• Start with your indoor project (walls, doors, and floor already in place).

• On the left sidebar, click DAS (or press D).

• If components exist, they’ll be listed — otherwise, click Add Components.

⚙️ Step 2: Add a Signal Source

1. Select Signal Source as your component type.

2. Choose your vendor.

3. Define:

   • Number of ports

   • Carriers (add multiple carriers with different power levels)

4. The signal source now appears in your component list.

📡 Step 3: Add Remote Units (ROUs)

• Place remote units (e.g., one here, here, and here).

• Click on a remote unit to view:

  • Bands supported

  • Transmission power

🔗 Step 4: Connect with Fiber Optics

• Use fiber optic connections to link your signal source and remote units.

• Example: connect signal source → ROUs.

• Add antennas (e.g., place three) and connect them with fiber optics.

📊 Step 5: View Bands

• At the top, you can see which bands are active.

• Example: If the signal source supports N41, you’ll see it listed in the DAS view.

🔀 Step 6: Daisy-Chain Remote Units

• Connect ROUs in a daisy-chain using fiber optics.

• This extends coverage and signal distribution.

➗ Step 7: Build a Passive Network

1. Add a 1x2 splitter.

2. Connect ports with QAX cables:

   • Connect from splitter → remote units.

   • Ensure correct power flow.

3. As you move cables, the system calculates attenuation and displays the updated signal power.

✅ Your indoor DAS design is now complete with signal sources, ROUs, antennas, and passive components all connected.
