A system and method for determining assigned frequencies for wireless microphone systems (WMSs) at a venue. Each WMS comprises a transmitter and a receiver. Each transmitter may comprise an IoT device connected to the transmitters and a server via a network. A first input for requesting the assigned frequencies is received at a transmitter which sends the request to the server via the network. The server determines intermodulation free frequencies based on chained stages and predefined data describing the WMSs at the venue and transmits the intermodulation free frequencies to one or more transmitters at the venue. Each WMS receives an intermodulation free frequency as an assigned frequency. A second input for requesting validation of an assigned frequency is received at a transmitter which sends the request to the server. The server determines and sends a validation status of the assigned frequency to the transmitter which displays the validation status.
