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 3

Place the Network Unit (NU).

Place the NU in the location where you get the best cellular signal.

Step 2

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.
