How it works

1. Find the best cellular signal
2. Place the Network Unit
3. Place the Coverage Unit
4. Use app to optimize setup

Sample Layouts

  1. Use your phone to find the best cellular signal. Typically you will get the best signal near a window.
  2. Place the Network Unit (NU) in the location where you get the best cellular signal.
  3. Place the Coverage Unit (CU) in the location where you need improved coverage.
  4. Using the CEL-FI WAVE app, finish setup and activation.
Move the CU further away from the NU to maximize coverage. The total coverage area equals twice the distance between the NU and the CU. The maximum distance is up to 100 dB path loss.
