As the Mount Kelvin control network (which is based on mesh technology from Wirepas) runs on the 2.4 GHv ISM band used by Bluetooth and Wifi devices, interference with other radio devices cannot be ruled out. To mitigate this issue, the network attempts to find quiet channels in the band to ensure reliability of both the Mount Kelvin network and other radio networks.
