Frequency is one of the important considerations when we buy a wireless microphone. Different countries have different frequency requirements. Only when the right frequency is Selected, the microphone can be used normally!
 
UHF (400 MHz and up) has been the standard for many years now and typically gives the strongest and best performance. In recent years, the FCC has placed restrictions on the frequencies of operation for wireless microphones.As on June 12, 2010, according to FCC documents, all wireless microphone devices that use the 700MHz band are prohibited from being sold. Equipment operating in this frequency band is required to stop using the equipment or modify this frequency band. The FCC mentioned that the reason for the cleanup of the 700Mhz equipment is that the original 700Mhz wireless microphone and loudspeaker products have occupied the frequency used for equipment in the public safety field.But wireless frequencies can still vary. The best combination of long transmission distance and clear frequencies is in the 470 to 548Mhz bands.You can also find a number of wireless microphone systems that operate in the 2.4GHz band. Be aware that the 2.4GHz frequency band is the same as your computer Wi-Fi and is potentially subject to interference from microwave ovens. Their operating range is also much shorter. Use 2.4GHz wireless microphones only in smaller rooms with no obstructions between the transmitter and receiver antennas.

Now, in 2023, the law of the United States is clear: "The manufacture, import, sale, lease, offer for sale or lease, the manufacture, import, sale, lease, offer for sale or lease, or shipment of wireless microphones or similar devices intended for use in the United States that operate on the 600 MHz  service band frequencies (617-652 MHz and 663-698 MHz) is now prohibited. See FCC 15-100, FCC 15-99, FCC 17-95,  DA 17-709."
