Find the best Cellular Signal.
For Cel-Fi PRO to work correctly, you need to have either a 3G, 4G or LTE signal.
Typically, you will get the best signal upstairs near a window.
Step 1
Place the Coverage Unit (CU).
Place the CU in the location where you need improved coverage.
Step 2b
Place the Network Unit (NU).
Place the NU in the location where you get the best cellular signal.
Step 2a
Optimize Coverage.
For best results, try moving the CU around to a few different spots. Typically, the farther the units are apart,
the better coverage you will have. Although, it is possible to move the units too far apart.
