Yes! Cel-Fi adheres to the same basic regulatory rules for device coexistence as Wi-Fi in the 5GHz band. We recommend at least 1 meter separation between devices.
What to do if you think your Wi-Fi Access Points and Cel-Fi are using the same channels:
If your Wi-Fi Access Point(s) are 5 GHz devices and in Auto channel selection mode, we recommend re-enabling your Access Points once the Cel-Fi system has been installed and is running. In Auto mode the Access Points should see the channels used by Cel-Fi and avoid them. Or alternatively if channel selection is Manual and not Auto, try selecting low channel numbers.
